Title: Ralink RT2870 based USB Wireless N adapters (Ubuntu)
Post by: Mark Greaves (PCNetSpec) on April 10, 2010, 01:44:57 pm

BE AWARE
For kernels >= 2.6.35 make sure you read the the EDIT.

If you want to know which kernel you are using, open a terminal and enter:

Code: [Select]

uname -r

(if it's greater than, or equal to 2.6.35, be sure to follow the instructions in the EDIT.

In Ubuntu 9.10 (Karmic), Ubuntu 10.04 (Lucid), and Ubuntu 10.10 (Maverick) there is an issue with USB Wireless N adapters based on the Ralink RT2870 chip.
The issue seems to be that 2 (conflicting?) driver modules are loaded... rt2870sta and rt2800usb... resulting in no wireless access.

The solution is to blacklist the rt2800usb module if it is loaded.

To see if they are both loaded, enter this in a terminal:

Code: [Select]

sudo lsmod | grep rt28

if they are both loaded, blacklist the rt2800usb module by opening the /etc/modprobe.d/blacklist.conf file (as root)

Code: [Select]

sudo gedit /etc/modprobe.d/blacklist.conf

and add the line:

blacklist rt2800usb

then save the file and reboot.

If after rebooting you can now 'see' the network, but it will not accept a WPA key (WEP seems fine)... you need to recompile the driver with WPA support... the driver can be found here:

2010_0709_RT2870_Linux_STA_v2.4.0.1.tar.bz2 (http://eng.ralinktech.com.tw/license_us.php?n=2&p=0&t=U0wyRnpjMlYwY3k4eU1ERXdMekEzTHpBNUwyUnZkMjVzYjJGa05ETTVOalU0TXpVeU5pNWllakk5UFQweU1ERXdYekEzTURsZlVsUXlPRGN3WDB4cGJuVjRYMU5VUVY5Mk1pNDBMakF1TVM1MFlYST1D) (you can enter 'any' name and email)
or
Ralink Linux Driver Page (http://eng.ralinktech.com.tw/en/Products/support.php?sn=501)
(~~HINT~~ - ~~change the files extension to tar.gz before unpacking... for some reason it comes up as an invalid bz2 archive, but unpacks properly as a tar.gz~~)

Before compiling - you are going to need to install build-essential, and linux-headers-generic.

Code: [Select]

sudo apt-get update && sudo apt-get install build-essential linux-headers-generic

If you use WPA/WPA2 encryption, you will have to change the lines
HAS_WPA_SUPPLICANT=n
and
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=n

in:
/os/linux/config.mk
(inside the unpacked driver)

to
HAS_WPA_SUPPLICANT=y
and
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y

Once you have changed these to =y and saved the config.mk file...

[EDIT]
Newer kernels >= 2.6.35 will fail to compile (make) the driver because the driver makes use of the functions usb_buffer_alloc() and usb_buffer_free() which were renamed in kernel 2.6.35 .. so if during the next (make && make install) step it fails with this error:

Quote

make[2]: *** [/home/mark/Desktop/RT2870/os/linux/../../common/cmm_mac_usb.o] Error 1
make[1]: *** [_module_/home/mark/Desktop/RT2870/os/linux] Error 2
make[1]: Leaving directory `/usr/src/linux-headers-2.6.35-27-generic'
make: *** [LINUX] Error 2

or similar.

The fix is to cd to the driver source directory (eg. 2010_0709_RT2870_Linux_STA_v2.4.0.1), and run the following 3 commands which will clean the build directory and replace the old calls with the new ones:

Code: [Select]

make clean
find . -name \*.[ch] -exec grep usb_buffer_alloc "{}" ";" -exec sed -i 's/usb_buffer_alloc/usb_alloc_coherent/g' "{}" ";"
find . -name \*.[ch] -exec grep usb_buffer_free "{}" ";" -exec sed -i 's/usb_buffer_free/usb_free_coherent/g' "{}" ";"

(hitting enter after each line)

Or, I've uploaded a pre-modified version of the driver that WILL compile on kernels >= 2.6.35 here:
2010_0709_RT2870_Linux_STA_v2.4.0.1.tar.bz2 (http://bit.ly/eZHx0J)

Then carry on with the "sudo su" and "make && make install", as per the instructions below.
[END EDIT]

To compile and install, open a terminal and enter:

Code: [Select]

sudo su
make && make install

It is important here not to use "sudo" alone, but "sudo su" because with sudo for some reason the installation script fails to create the necessary files and folders.

Now, while still root modprobe the driver module:

Code: [Select]

modprobe rt2870sta

Give it a minute to create the ra0 device node, and network manager should now be able to display all visible wireless networks in your area, meanwhile you can stop being root.

Code: [Select]

exit

Make sure that ra0 is up and running as it's supposed to:

Code: [Select]

iwconfig

and check for a section similar to:

Quote

ra0 RT2870 Wireless ESSID:"" Nickname:"RT2870STA"
Mode:Managed Frequency=2.412 GHz Access Point:
Bit Rate=54 Mb/s
RTS thr:off Fragment thr:off
Link Quality=100/100 Signal level:-29 dBm Noise level:-71 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

To make sure the module is loaded after a reboot, add it to the /etc/modules file:

Code: [Select]

sudo sh -c 'echo rt2870sta >> /etc/modules'

Your wireless card should now be working (it may require a reboot first)... Use network manager to set your WEP/WPA(2) key, and connect to your network.

Hi Mark

I have been looking for a solution to this problem for ages on and have tried allsorts with my patchy but growing knowledge of linux. I am now running xubuntu 11.04 on an ancinet laptop. The USB wifi unit is recognised in 11.04 without the need for blacklisting and I can see my network but canont login. On your modified driver for later kernals do I need to change thge WPA_Supplicant info or have you done that already? I am going to try this tonight.

I must say this is the clearest linux forum that I have come across.

Thanks

SSID

I've NOW changed the WPA settings to Y in the pre-modified driver :)

Hi Mark,

Thank you very much for the tip on the compilation error, this certainly saved me quite a bit of trouble.

I'm up and running now (on Natty), but I notice that iwconfig is only reporting 54 Mb/s. As I have an "N" speed router & adapter (and is configured as such), shouldn't I be seeing speeds higher than this?

Thanks again...

Are there any slower wireless devices connected to the router ?

AFAIK, a mixed mode b/g/n wireless router (or access point) will default to the slowest protocol depending on what devices are connected wirelessly.
(ie. an 802.11n router that supports b/g/n will scale back to 802.11b if a device with only 802.11b capabilities connects to it... slowing ALL other device connections)

You could try changing the (default) configuration:
WirelessMode=5
line in
/etc/Wireless/RT2870STA/RT2870STA.dat

Code: [Select]

sudo gedit /etc/Wireless/RT2870STA/RT2870STA.dat

to
WirelessMode=6
to force a Wireless "N" connection.
(be aware, if there are any slower devices connected to the router this mode may leave you unable to connect)

Some people say setting it to:
WirelessMode=7
or
WirelessMode=9
helps, in mixed mode... ie.dropping support for 802.11b and/or 802.11a

WirelessModes -

0: legacy 802.11b/g mixed
1: legacy 802.11b only
2: legacy 802.11a only
3: legacy 802.11a/b/g mixed
4: legacy 802.11g only
5: 802.11a/b/g/n mixed
6: 802.11n only
7: 802.11g/n mixed
8: 802.11a/n mixed
9: 802.11b/g/n mixed
10: 802.11a/g/n mixed

Don't forget to save the RT2870STA.dat file, and restart the wireless (or reboot).

It's all in the README_STA file in the driver archive ;)

Hi,

I recently download Ubuntu 11.04 and created a dual-boot system. This is my second experience with Linux in general in about 12 years, and so far, so good. However, I'm trying to get it to connect to the internet and I can't seem to get it to.

I have an AE1000 USB Adapter, and following the step-by-step wizard included with ubuntu for configuring wireless settings got me as far as "Great! Now go to the device drivers page" which just brought me back to the same instruction page I was on. But it did yield the fact that the chipset within my USB Adapter (which it was able to recognize as being plugged in, if not being able to load some sort of driver for initializing it) was an RT2870.

I'm a Windows user; I'm used to the command prompts in MS-DOS and the Terminal system is somewhat familiar to me, but I still can't get it to do much of anything. Is there anyway you could perhaps make it simpler for a complete Noob such as myself to follow your instructions? I got as far as saving that reworked driver you made to my Linux partition, but I just can't get to it through terminal. In windows you can change directories via "cd" much as linux does, but I must be getting some critical element of the syntax wrong, because no matter how I vary the spacing, or use "/" versus "\" or including multiple folder files to provide the exact file path name, it always returns a file not found message. Which is somewhat frustrating.

As soon as I figure out more of the way commands are entered into terminal, I could perhaps piece together the rest of what I need from posts. In fact, I'm about to google that now, so, if I don't have it *solved* by the time I get a reply, at least my need for simpler instructions won't be as---stringent. Thank you in advance!

Can you confirm you can browse to the file using the nautilus file manager, and where it is ?

If you downoaded it with Firefox (with default settings) it is probably in the "Downloads" directory.

If you can't find it, download it again with these commands:

Code: [Select]

cd ~
wget -O 2010_0709_RT2870_Linux_STA_v2.4.0.1.tar.bz2 "http://bit.ly/eZHx0J"

You with then find the 2010_0709_RT2870_Linux_STA_v2.4.0.1.tar.bz2 file in your "Home" directory.

you can unpack it through the GUI, or with:

Code: [Select]

tar -jxvf 2010_0709_RT2870_Linux_STA_v2.4.0.1.tar.bz2

cd into the unpacked directory:

Code: [Select]

cd ~/2010_0709_RT2870_Linux_STA_v2.4.0.1

then carry on from the:

Code: [Select]

sudo su
make && make install

Extra info...

Just prior to posting this, I've updated the pre-modified driver to also include the WPA/WPA2 modification... so it would probably be a good idea to re-download it anyway.

BTW, the ~ in the above paths just means the current users "Home" directory... it saves you having to type /home/username

If you want to get to grips with the Linux command line, some of these free online books might help -
http://linuxforums.org.uk/ubuntu/ubuntu-andor-generic-linux-books-or-text-()/ (http://linuxforums.org.uk/ubuntu/ubuntu-andor-generic-linux-books-or-text-()/)

If you want to know more about a particular command, you can enter "man" in front of it to see the commands man page (manual)... eg.

Code: [Select]

man tar
man make
man modprobe

etc.
To exit the man page, just hit the Q key.

I can confirm I can browse to the file using nautilus manager, and it was in the downloads folder. What was really wrong was the fact I was not including the '~' symbol. Thank you for the heads-up about that one.

I downloaded your revised driver, accessed it using Terminal and it seemed to throw a couple of memory warnings. Went to install it again, and it said directories were already created, so I'm not sure if all went well upon download or not.

However I seem to have run into a snag, in that the 'iwconfig' command still didn't return all of the information that you showed would've been available had all gone well. It is probably pertinent to mention at this point that I did not follow the edits for blacklisting. I will do that now, just to say I tried everything. I was confused, as you mentioned specific versions, and the dimly hopeful feeling in my soul said, "Well, maybe they fixed it in 11.04." My bad on that one.

First, let's confirm your card IS an RT2870 based card... can you post the output from:

Code: [Select]

sudo lshw -C network

entered into a terminal.

I can confirm the driver builds and installs properly on 11.04, so I'm guessing something went wrong on your build... and I'm *guessing* (because of your "directories were already created" comment) that the command wasn't run as root... but we'll get to that once you post the output from the above command ;)

Title: Re: Ralink RT2870 based USB Wireless N adapters (Ubuntu)
Post by: Noobuntu on May 17, 2011, 03:19:05 am

I ran that command and it kicked out:

Description: Ethernet Interface
Product: Netlink BCM 57780 Gigabit Ethernet PCIe
Vendor: Broadcom Corp
Physical ID: 0
Bus Info: . . . . . . and it all goes on. This, as you may have guessed is all information related to my onboard network adapter which I can visually confirm is not what connects me to the Internet. Never has been, never will, and I forgot about it until now.
I have had to use my windows OS to sign onto the internet and talk with you here, and I've been copy/pasting posts/directions inbetween. The reason I didn't go much further is because, as I discovered, the disk I've been using was configured by windows as a pseudo-USB device that will let me read off it---but not write to it, at least with Ubuntu. So I wrote down enough to convey the general impression that this is in fact not my usb device at all.. Since I didn't have another disk.

Ubuntu doesn't even seem to recognize that my USB adapter exists. And I can confirm that I was in root when I ran that program, because it prompts me to enter a password in when I access any sudo commands and will not run until I do.

Do you know of any off-the-shelf internet adapters that do work with Linux right out of the box?

Erm... If you don't have an active internet connection in Ubuntu, this command will have failed:

Code: [Select]

sudo apt-get update && sudo apt-get install build-essential linux-headers-generic

It needs an active internet connection to download/install those files... which would explain why the "make && make install" command also failed.

So connect with a cable, and try again.

If that doesn't work...

Can you unplug your USB wireless adapter... wait 5 seconds... plug it back in, then run:

Code: [Select]

dmesg | tail -n 15

and post the output.

and the FULL output from:

Code: [Select]

sudo lshw -C network

and

Code: [Select]

lsusb

If you can't mount and write to the windows disk/partition... use a cabled connection to your router, or copy the output to a USB stick.

[ 643.711646] usb 2-1.4: new high speed USB device using ehci_hcd and address 6

This tells us that it is detecting a USB device is being attached, but the system isn't recognising it as a wireless adapter.

you missed the:

Code: [Select]

lsusb

command... hopefully this will give us the vendor and device ID string, so we can find out what the adapter is.

There may also be an issue with your sources.list as you shouldn't be getting those Ign lines

Is this a fresh install of natty, or an upgrade ?

Post by: Noobuntu on May 17, 2011, 05:22:27 am

This is a fresh install. I'm utterly new to Linux of any sort; the last thing I tried was Redhat 6.0. :-[

[EDIT] This is also the first time I've ever physically connected to ethernet. The last hardline I ever had connected to my computer was indeed a regular phone line. Once we upgraded to something faster, I automatically switched to wireless. . . It goes a whole lot quicker than wireless does. Think I might just get about 30 feet or so of line and call it good, lol. Seeing as how the adapter that came with the computer works and all. . . .

OK, I've added your cards ID string to the driver, so you're going to have to download it again...

First delete everything (files and folders) in your home folder that has RT2870 in it's name.

Now download the new driver:
http://dl.dropbox.com/u/11876059/Noobuntu.tar.bz2 (http://dl.dropbox.com/u/11876059/Noobuntu.tar.bz2)

and put it in your home folder.

unpack it with:

Code: [Select]

cd ~

then:

Code: [Select]

tar -xjvf Noobuntu.tar.bz2

change to root:

Code: [Select]

sudo su

cd into the unpacked directory:

Code: [Select]

cd /home/username/2010_0709_RT2870_Linux_STA_v2.4.0.1

(be sure to change the username to YOUR username in the above command)
now build the driver:

Code: [Select]

make

now install it with:

Code: [Select]

make install

Then see what:

Code: [Select]

modprobe rt2870sta

then:

Code: [Select]

exit

then:

Code: [Select]

iwconfig

gives you.

If it works, but doesn't survive a reboot... run this:

Code: [Select]

sudo sh -c 'echo rt2870sta >> /etc/modules'

and reboot again.

Post by: Mark Greaves (PCNetSpec) on May 17, 2011, 06:38:32 am

I think I've found the problem... even though your card identifies itself as an RT2870, it needs the RT3572 driver...

did you enter this command ?
sudo sh -c 'echo rt2870sta >> /etc/modules'

if so, run this:

Code: [Select]

sudo gedit /etc/modules

find the line that reads
rt2870sta
and remove it... then SAVE the file and exit.

I'm going to go get the correct driver and modify it... back in a bit with instructions.

I did enter the 'sudo sh -c 'echo rt2870sta >> /etc/modules'' command, but then I rebooted. Then I entered the 'sudo gedit /etc/modules' command and a window opened up with 5 lines that read 'rt2870sta' but the terminal yielded and interesting error:

Mr. Greaves,

i *am* talking to you via a wireless internet connection. It didn't survive the reboot, so I ran that command, rebooted again, whereupon a strange and miraculous thing occurred; it started giving me wireless options in the network manager, and after a quick reboot of my ethernet box sitting atop the router, and a quick unplug of the wireless adapter, and a tense, emotionally-charged wait as it finished detecting my network, it gave me access to the World Wide Web. I am probably gonna sit here and give you several more "applause" clicks over the course of the next couple of days to accurately reflect the number of times you came back to this page and did not give up until it was done. I truly and sincerely appreciate it, thank you.

Logan

PS --- I think I have passed the point of no return with Linux startup times and am thoroughly enthralled with the operating system now. I will probably continue to use this operating system for years to come.

The RTL8192SU drivers *only* apply to the HWNUm-300... The HWNU-300 *does* use the RT2870STA driver.

There is a pre-modified version (with the HWNU-300 ID string added) linked to further down the page. (in post #39)
[END EDIT]

You are using the wrong drivers... the Belkin HWNU 300 and HWNUm-300 appear to use the RTL8192SU chipset.

The RTL8192SU drivers can be downloaded here:

http://dl.dropbox.com/u/11876059/Y0a0bon_RT2870_Linux_STA_v2.4.0.1.tar.bz2 (http://dl.dropbox.com/u/11876059/Y0a0bon_RT2870_Linux_STA_v2.4.0.1.tar.bz2)
just in case.

Thank you :) Yes it's working, i did the same thing as you.
Can I quote you in the contributors of the wiki: http://doc.ubuntu-fr.org/| (http://doc.ubuntu-fr.org/|) (the french community ubuntu documentation)?

Great!:) And does your method work on 11.04?

Post by: Mark Greaves (PCNetSpec) on June 01, 2011, 05:39:18 pm

The driver will compile/install in 11.04 (after modification), but I'm not sure if the blacklisting of rt2800usb is still necessary.

Title: Re: Ralink RT2870 based USB Wireless N adapters (Ubuntu)
Post by: Y0a0bon on June 01, 2011, 06:10:03 pm

Ok, i will try with and without blacklisting rt2870usb, thank you :)

Can you let me know if the blacklisting is still required in Natty ?

Hi,
I'm new here. First of all I would like to say you should really change that banner...
Not only this site should be seen by any one using Linux in the UK but it should be seen by anyone in at least Europe.
You're the first site with a recipe that make my wireless USB dongle to display at least some form of life with Ubuntu Maverick.

However it displays not enough of life. If I install the driver like I'm told in this thread. It indeed starts blinking but after that there's trouble.
When typing in a command the server freezes always (except for ls, lsub, lspci and this type of commands). Even typing mc in order to start Midnight Commander results in a freeze.

Fortunately my old 2.6.31 Karmic kernel is still working...

I assume you probably also know an answer for my problem so I'll give you as much details as possible.

System: Ubuntu 10.10
Kernel: 2.6.38-9
Wireless: USB dongle Logilink WL-0049a. According to some fora it requires the RT 3070 driver but on the 2.6.31 kernel it takes RT2870.

I'll attach a dmesg output of one failed run.

Title: Re: Ralink RT2870 based USB Wireless N adapters (Ubuntu)
Post by: Mark Greaves (PCNetSpec) on July 02, 2011, 08:54:12 pm

The site is "primarily" aimed at UK users, but everyone is welcome as long as they don't spam :)

With the card plugged in, can you post the output from:

Code: [Select]

lsusb

and

Code: [Select]

sudo lshw -C network

and

Code: [Select]

iwconfig

If the lsusb reports the Device ID as ID 148f:3070 Ralink Technology, Corp .. Then you DO need the RT3070 driver... you can download a pre-modified version here:
http://dl.dropbox.com/u/11876059/2011_0107_RT3070_RT3370_Linux_STA_v2.5.0.1_DPO.tar.bz2 (http://dl.dropbox.com/u/11876059/2011_0107_RT3070_RT3370_Linux_STA_v2.5.0.1_DPO.tar.bz2)
(pre-modified = WPA(2) enabled) the above driver should compile properly in 2.6.38, as long as you have the headers and build-essential installed

If you need help compiling and installing, just ask :)

BTW, Have you installed a later kernel ? .. I wasn't aware Maverick was on 2.6.38, I thought it was on 2.6.35.... Natty is on 2.6.38

also, make sure rt2870sta is NOT blacklisted.

But you *may* have to blacklist rt2800usb

Post by: q7icmfm1x0h609c6xiok on July 02, 2011, 10:24:14 pm

Sure, I saw the org.uk extension so I guessed that the site was aimed at UK users. But it works for Dutchmen too ;)
Thanks for replying this soon.

lsusb indeed reports the stick to be a 148f:3070 so apparently it needs the RT 3070 driver but then I don't know why it seems to use the RT 2870 driver in the Karmic kernel according to the lsmod command.
So knowing this, being in possession of a RT 3070 based dongle, I guess my issue is a little bit inappropriate in this thread. But since I started it here it is probably best to leave it here.
In the meantime I've downloaded the driver you've provided. I hope I can test it tomorrow and I will report the results back to you.

You say RT2870 should not be blacklisted. Since I've now installed your version of that driver will it also work if I leave it that way or do I need to revert to the "original" driver?

Concerning the 2.6.38 kernel: Since it's there I apparently have installed it though I can't recall why I did so and when I did that. I'm trying to get that dongle working ever since Lucid so I've tried suggestions from several sites. Recently I've tried an experimental 2.6.39 kernel either but again with no results.

At this moment I can't provide you with the results of sudo lshw -C network and iwconfig because both commands currently result in a system freeze. I can do it in the old Karmic kernel but I guess that doesn't make much sense.

Hi, I have also recently brought a RT2870USB adapter but am having difficulty installing under ubuntu 11.4. I have tried making the driver based on the contents of the supplied cd, but am getting the following output:

After completing your instructions, I had no success. I assumed this was related to the warnings in the output. I tried the alternative download you provided and received a slightly different set of warnings:

Are these warnings going to stop the driver from working in there own right, or am I missing something else. As requested on previous posts here are some additional details

@ q7icmfm1x0h609c6xiok

No you don't have to revert to the original rt2870sta... and I don't *suppose* it will hurt to blacklist rt2870sta if it get loaded automatically at boot and interferes with the rt3070sta driver... but I doubt if it will.

You *may* have to modprobe rt3070sta, and add it to /etc/modules if it doesn't survive a reboot.

Earlier drivers rolled rt3070 based cards into the rt2870sta or rt2800usb drivers... there were no specific rt3070sta drivers at the time... so an 'early' rt2870 driver would *probably* work with your card if you could get it to compile.

@ jamesrl

You too are using the wrong driver... you need this one:
http://dl.dropbox.com/u/11876059/2011_0407_RT3070_RT3370_RT5370_RT5372_Linux_STA_V2.5.0.2_DPO.tar.bz2 (http://dl.dropbox.com/u/11876059/2011_0407_RT3070_RT3370_RT5370_RT5372_Linux_STA_V2.5.0.2_DPO.tar.bz2)

You'll have to modify the commands accordingly, and modprobe rt5370sta

and if necessary add rt5370sta to /etc/modules

The warnings should be nothing to worry about.

and
crc_ccitt 12595 1 rt2870sta
just means crc_ccitt depends on the rt2870 module being loaded

this error in the drivers you first tried:

Quote

WARNING: modpost: missing MODULE_LICENSE() in /home/user/2011_0225_RT5370_RT5372_Linux_STA_V2.5.0.1_DPO/os/linux/rt5370sta.o
see include/linux/module.h for more information

was probably caused by a missing:
MODULE_LICENSE("GPL");
line in usb_main_dev.c ... which leads to the "Unknown symbol" errors you were getting in dmesg... it *should* be fixed in the driver I linked to.

I can't test that it's been fixed though, so you'll have to install the driver and tell me if you're still getting those errors in dmesg, or you get this error when modprobe(ing) rt5370sta:

FATAL: Error inserting rt5370sta (/lib/modules/<your kernel version>/kernel/drivers/net/wireless/rt5370sta.ko): Unknown symbol in module, or unknown parameter (see dmesg)

let me know and I'll add the line and upload the driver for you.

If the lsusb reports the Device ID as ID 148f:3070 Ralink Technology, Corp .. Then you DO need the RT3070 driver... you can download a pre-modified version here:
http://dl.dropbox.com/u/11876059/2011_0107_RT3070_RT3370_Linux_STA_v2.5.0.1_DPO.tar.bz2 ([url]http://http://dl.dropbox.com/u/11876059/2011_0107_RT3070_RT3370_Linux_STA_v2.5.0.1_DPO.tar.bz2[/url])
(pre-modified = WPA(2) enabled) the above driver should compile properly in 2.6.38, as long as you have the headers and build-essential installed

also, make sure rt2870sta is NOT blacklisted.

But you *may* have to blacklist rt2800usb

Well, I've tested this and unfortunately it doesn't work out.
- The driver you've provided shows the license warning, but I don't think that 's a problem.
- Make install overwrites the contents of /etc/Wireless/RT2870STA/RT2870STA.dat, while I thought it should operate on /etc/Wireless/RT3070STA/
- According to dmesg (attached) the driver from the staging folder is loaded, but I think that's not the one generated by this package. So I need a more sophisticated method to make the computer ignore that staging folder without deleting it, because I need it as long I can't get the wireless stick to work in a different kernel than 2.6.31.
- Modprobe rt2870sta causes things not to work
- Modprobe rt3070sta results in a message that it couldn't find the module (or driver; I can't remember exactly).

Once again I forgot to perform: sudo lshw -C network and this time I did iwconfig, but that doesn't detect any wireless network.

Thanks for your quick response.

I have downloaded the driver you supplied, but when I modprobe I received either the following messages

after install
FATAL: Error inserting rt5370sta (/lib/modules/2.6.38-8-generic/kernel/drivers/net/wireless/rt5370sta.ko): Device or resource busy

after restarting pc

I have had a scan through of the output from make and cant see any of the problems you mentioned.

The following is the output received with new driver. Thanks again for all your help.

OK try this... install the latest drivers:
http://dl.dropbox.com/u/11876059/2011_0407_RT3070_RT3370_RT5370_RT5372_Linux_STA_V2.5.0.2_DPO.tar.bz2 (http://dl.dropbox.com/u/11876059/2011_0407_RT3070_RT3370_RT5370_RT5372_Linux_STA_V2.5.0.2_DPO.tar.bz2)
(get them from the above link, not the ralink page)

make and install them

and make sure NONE of the following are blacklisted

rt2x00lib
rt2800usb
rt2x00usb

BTW, AFAIK, 2.6.38 and 2.6.39 don't contain rt3070sta.ko they use rt2870sta.ko for rt3070 based cards .. so if it IS on your system, it might be a good idea to blacklist rt3070.sta, and modprobe rt2780sta

make && make install again... but MAKE SURE you run make with root privileges

Code: [Select]

sudo su
make && make install

then reboot.

If you wireless doesn't work,, can you send the output from

@Mark Greaves:
To whom are you talking now (meaning the 09:58:53 pm post) ? To me (q7icmfm1x0h609c6xiok) or to jamesrl?
Our issues look more or less similar and the drivers you've supplied are more or less identical judging by the filename?
(All right I've noted the edit that post is directed to me...)

B.T.W.: Because of your remark about kernel 2.6.38 being not standard for Maverick I did this test with the current 2.6.35 kernel.
Because jamesrl is using the non standard 2.6.38 kernel (according to the posted output) I guess maybe it would be easy for the conversation if I continue with that one too instead of the standard kernel?

The drivers ARE the same ones... I want you to try those ones (newer), but make sure

rt2x00lib
rt2800usb
rt2x00usb

AREN'T blacklisted.

and modprobe rt2870sta

if that doesn't work... remove/blacklist rt3070sta (if it is loaded), and try modprobing rt2870sta again.

Did you upgrade to 10.10, or was it a fresh install ?

BTW, jamesrl IS using the default kernel... he's running 11.04 :)

I didn't realise there was a limit on name length in chat :( .. you learn something every day ;)

You've clearly a lot of expertise in Linux on the other hand I'm good in website programming (that's how I make money). Therefore I know that the 16 character is not exactly a limit in the chat but that limit is imposed by the login screen. The code defining the username box says:
<input type="text" name="user" id="userNameField" maxlength="16"/>
If you change the number in maxlength="16" in something different or if you delete that part all together then the limit is set to the new number resp. there's no limit anymore.
Note: I can see it is a PHP page so if you look into the PHP source you´ll probably see something that differs a bit from what I've pasted.

Anyway, back on topic:
- The new version of the driver didn't work. Instead in dmesg there are even more warnings issued. The relevant part is:

[ 22.875013] usbcore: registered new interface driver rt2870
[ 22.880899] rt3070sta: Unknown symbol usb_register_driver (err 0)

So it seems to register first rt2870 and somewhat later rt2800usb and then it renames the interface name which already was the wrong one?!

That sequence of warnings led me to a new thought. Your driver contains a readme file that file talks about changing certain values in the rt2870.dat file, like setting the SSID and so on. Is it necessary to do that because you didn't mention it anywhere in this thread.

B.T.W.: I've finally performed the actions you've asked for:

lsmod | grep rt2 gives:

rt2800lib 30847 1 rt2800usb

lshw -C network gives as relevant part:

And for no particular reason I've tried /etc/init.d/networking restart
That command replied something about not being able to start wpa_supplicant.

and from iwconfig I can't find the file with the output but it talks about wlan1 not being associated too.

My 10.10 is an upgrade, not a fresh install. In the past I've started with Ubuntu 9.04.

I take it the wpasupplicant package is installed ? .. do you use WPA/WPA2 encryption ?

can you send the contents of /etc/network/interfaces

and the output from

Code: [Select]

sudo rfkill list

Maybe a stupid question, but I also take it networking IS enabled in network manager ?

@Mark Greaves

Sadly no connection. Below is the information you requested. I looked at my black listed drivers but could not see anything similar to the rtlink drivers. Also I ensured I was using the latest driver you supplied and with root permissions
sudo su
make && make install

Post by: q7icmfm1x0h609c6xiok on July 04, 2011, 10:53:36 pm

I'm sorry to hear that on jamesrl's computer things are still not working either. There's apparently a lot of work to do by the Ubuntu community to support wireless dongle decently.

In the meantime I've done an experiment on my own. Apart from the Ubuntu Server I own a laptop the runs on Ubuntu 11.04 (kernel 2.6.38-10) and I've a second WLAN usb stick that also identifies to be a 148f:3070. So I decided to find out what happened if the internal WLAN card was disabled and instead the WLAN usb stick inserted. Result: it connected immediately to the wireless network. So we can conclude that kernel 2.6.38 supports WLAN usb sticks that identify as 148f:3070. I noticed a few interesting things:
- According to lsmod it does not use RT2870 or RT 3070 drivers at all but it takes RT2x00:
rt2870sta 450556 0
rt2800usb 18235 0
rt2800lib 45181 1 rt2800usb
crc_ccitt 12667 2 rt2870sta,rt2800lib
rt2x00usb 20330 1 rt2800usb
rt2x00lib 49235 3 rt2800usb,rt2800lib,rt2x00usb
mac80211 294370 3 rt2800lib,rt2x00usb,rt2x00lib
parport_pc 36959 0
cfg80211 178528 3 rt2x00lib,mac80211,r8192se_pci
parport 46458 3 parport_pc,ppdev,lp

- Even more interesting: it appears that the name has changed. It is not ra0 any longer but it seems to be wlan0 or wlan1 whatever is available. See this:

wlan1 IEEE 802.11bgn ESSID:"p2zFsepJ6jmue_MLehec2jVahWCW-jJE"
Mode:Managed Frequency:2.462 GHz Access Point: 00:04:0E:D0:8C:55

Encryption key:off
Power Management:on
Link Quality=33/70 Signal level=-77 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:2 Missed beacon:0

And this is confirmed by the output of lshw -C network:

*-network

physical id: 4
bus info: [email protected]:2.3
logical name: wlan1

configuration: broadcast=yes driver=rt2800usb driverversion=2.6.38-10-generic firmware=0.29 ip=10.0.0.12 link=yes multicast=yes wireless=IEEE 802.11bgn

So I've redefined my target. From the experiment I know that it should be definitely possible to get that adapter active in the new Ubuntu kernel and now I don't longer care about how to achieve this. If there's a nice driver package to do it that would be nice, but if I have to copy certain files between my laptop and my server I'll take that too as a viable option. Right now I'm interested in if we can identify why it does work in Ubuntu Desktop version but not in Ubuntu Server version.

And we've few open questions:

You asked if networking is enabled in network manager. Well that question is not relevant because there's no network manager. My server runs (of course) the Ubuntu Server version which has no desktop.
You asked if I was back on 2.6.35. It depends on how you see it. Currently there are multiple kernels on my server because I was hoping to find one in which the USB stick would work. I supposed the standard Maverick 2.6.35 kernel would be better so I did the tests on that one. But since that dongle on my laptop appears to work in 2.6.38 I'll rather like to continue with that kernel now.
You asked for /etc/network/interfaces. I can give you that:

auto ra0
iface ra0 inet static
address 10.0.0.19
netmask 255.255.255.0
gateway 10.0.0.140
wpa-driver wext
wpa-ssid <my ssid is normally here>
wpa-ap-scan 2
wpa-proto WPA RSN
wpa-pairwise TKIP CCMP
wpa-group TKIP CCMP
wpa-key-mgmt WPA-PSK
wpa-psk <I'd rather not publish the key online>

May be those ra0 items pose a problem now the interface name appears to be different?

A few supplemental observations:
My network is wpa/wpa2 mixed and it does not broadcast the ssid. Some fora state that will lead to problems. But in the old kernel 2.6.31 I can connect nevertheless.

You asked if wpasupplicant was installed. apt reports it's installed and it is the newest version, so that's a yes.

Sorry I didn't realise we were working on a server ::)

jamesrl's problem is different because his card doesn't seem to be being recognised at all... probably a device ID issue... need to think on that one a bit.

@Mark:
Sorry, but it didn't work.
For some weird reason in 2.6.35-30 the logical name has changed again and now it is once again ra0, so it should work but it doesn't.
On 2.6.35-28 the logical name is now wlan0 while a few days ago starting the 2.6.35-28 kernel resulted in a freeze.
Well, I can live with whatever name the interface has but now I can bring up wlan0 but it won't associate. May be something is wrong with my /etc/network/interfaces.
In this kernel and in a 2.6.38 kernel the led on the stick starts blinking like crazy but the stick can't associate.
My modemrouter registers in its log that it sees the connection attempts of the server but it refuses them (it does not log why). Is it possible that the encoded wpa-psk key in /etc/network/interfaces has to be adjusted according to the new situation and that the modemrouter refuses it because it is wrong? In the old 2.6.31 I still have network connectivity so in that case the wpa-psk key is not wrong.

I think I've messed up somehow certain things with blacklisting or whatever. I'm completely lost now and I think we need to repeat some steps.
Even better would be to completely remove the obsolete kernels including the drivers you've provided and then reinstall one current kernel and work with that. I know that before I discovered this website I've done things with backports but I don't know how to get rid of it.

@ q7icmfm1x0h609c6xiok

You can show a list of installed packages with:
dpkg --get-selections | less

or export them t a file in your home directory with:

Code: [Select]

cd ~
dpkg --get-selections >> paackag_list

or search for "backports" in the output with:

Code: [Select]

dpkg --get-selections | grep backports

are you still getting the wpa_supplicant error ?

It's entirely possible the WPA key is wrong, but only you would know that ;)

So lets find out if it *IS* just a WPA encryption problem... will it associate with an unsecured wireless access point ?
(ie. turn off wireless security in your modem/router for a test connection)

Nice, that it works for jamesrl!

@mark:
I've tried dpkg --get-selections and it detected 3 different backports. So like I said I've messed up things.
Furthermore there are several packages indicated as deinstalled (but the configuration files are seemingly still present). So currently I'm in the process of cleaning up things.

I'm still not convinced about that wpa_supplicant thingy. I've found an interesting webpage which describes that the security settings in /etc/network/interfaces can be included in /etc/wpa/wpa_supplicant.conf.
I'll try it and if it works with my currently working 2.6.31 kernel we'll know for sure that wpa_supplicant is working.
And I've found an article claiming that Ralink wireless usb adapters simply do work with stock drivers but this article follows an approach using udev rules.
I'll report back to you soon.

Title: Re: Ralink RT2870 based USB Wireless N adapters (Ubuntu)
Post by: q7icmfm1x0h609c6xiok on July 06, 2011, 09:56:29 pm

All right, I'm back again.

With the 2.6.31 kernel (with connectivity) the result of ps -A | grep wpa_supplicant is:
3332 ? 00:00:00 wpa_supplicant
So wpa_supplicant seems to be running.

I've made a new version of /etc/network/interfaces and now it's like this:

auto ra0
iface ra0 inet static
address 10.0.0.19
netmask 255.255.255.0
gateway 10.0.0.140
wpa-conf /etc/wpa_supplicant.conf
wpa-ap-scan 2

and my /etc/wpa_supplicant.conf looks like:

ctrl_interface=/var/run/wpa_supplicant
network={
ssid=<here the ssid>
psk=<here the key>
key_mgmt=WPA-PSK
proto=RSN WPA
pairwise=CCMP TKIP
group=CCMP TKIP

I was too lazy to reboot ;-)
so I did sudo /etc/init.d/networking restart
and I got the message:
wpa_supplicant: /sbin/wpa_supplicant daemon failed to start
run-parts: /etc/network/if-pre-up.d/wpasupplicant exited with returncode 1

So it seems that there's indeed something wrong with wpasupplicant.

B.T.W.: if I remove RSN from the proto statement in the original 2.6.31 network interfaces configuration in order to force a WPA2 connection the network connectivity breaks. If I put it back everything works.

What is the verbose (-v) output from ifdown and ifup ?

Code: [Select]

sudo ifdown -v ra0

and

Code: [Select]

sudo ifup -v ra0

Hopefully this will give us an idea where WPA is failing.

Post by: q7icmfm1x0h609c6xiok on July 08, 2011, 01:58:37 am

Those commands did not produce any useful results but in the daemon log I noticed wpa_supplicant parsing errors.
In the end I discovered that wpa_supplicant wants my SSID in between quotes. So my old 2.6.31`kernel is now running with wpa_supplicant.
After that success I decided to proceed but that resulted in disaster. I lost all network connectivity including the 2.6.31 kernel. I took me about 3 hours to repair the damage.
It seems that after a series of many changes the USB stick gets somehow confused, locks up and ignores all changes as instructed by the driver. The only way to make it work again is unplug it and replug after 1 minute.

During the session I noticed that the driver tries to read the contents of the file /etc/Wireless/RT2870STA/RT2870STA.dat and it ignores what wpa_supplicant instructs. The only way to make the driver to ignore that file is to remove or rename it.
Furthermore I found that kernel 2.6.38-9 still hangs so that one won't work I guess.
Kernel 2.6.35-30 and the experimental kernel 2.6.38-02063808 produces these two errors:
- WPA: unsupported CCMP Group Cipher key length 32 (32).
- RSN: failed to configure GTK.
Kernel 2.6.35-28 is not able to connect and times out each attempt.

And in the logs I've found an error that I can't link to a specific kernel right now. It says: Failed to disable WPA in the driver.

Post by: Mark Greaves (PCNetSpec) on July 08, 2011, 02:41:38 am

With all this swapping of kernels, are you recompiling the driver each time ?

I think your last idea of picking a kernel and then trying to get it to work would probably be the better idea... the default kernel is probably the one you should go with unless there is a specific reason not to... AFAIK these drivers should work with any (recent) kernel they are compiled for.

My suggestion would be to go back to the default kernel (whatever that is, I've forgotten which Ubuntu version you are running), recompile/install the drivers, then try to sort out the configs.

Swapping kernels seems fairly pointless, the drivers are loaded as a module, so are not part of the kernel.

Post by: q7icmfm1x0h609c6xiok on July 09, 2011, 01:38:58 am

Recompiling each time? Well, actually no I didn't. I assumed that compiling it once for each kernel was good enough. Besides as far as I know the RT3070 driver is used by none of the tested kernels they all go for RT2870.
Currently I use Ubuntu Server Maverick so the default kernel would be 2.6.35-30, so I´ll continue with that one.
I think this weekend I don't have much time for testing purposes so I probably won't do anything until monday.

Post by: q7icmfm1x0h609c6xiok on July 13, 2011, 01:26:32 am

Well, I've resumed testing again. In the process I've caused a major connectivity breakdown. No kernel could establish a connection not even the so far always working 2.6.31 kernel.
It took me 6 hours to repair things. So far I've found out that:

- rt2800lib and rt2800usb need to be blacklisted otherwise no connection will be established in any circumstances.
- It does not matter if rt2x00lib and rt2x00usb are not blacklisted.
And there's something that was not necessary before: I need to blacklist rt3070sta otherwise the connection will not come up automatically (however it can be brought up by ifup, but I want it to come up automatically).
I expect to do some further testing with kernel 2.6.35 in order to make that one work.
May be something has changed so I would like to ask you again which driver do you recommend?
Do we have a working mode that involves NO touching of /etc/network/interfaces and the wpa_supplicant stuff? Wpa_supplicant is working in the old kernel so I like to keep it that way.
I´m a bit worried about the /etc/Wireless/RT2870STA/RT2870STA.dat file. For some reason I have to remove it otherwise no connection will be established. I've tried to fill it in with appropriate values but these are probably not appropriate enough because it's not working. Removing that file obviously causes messages in the log that the file can't be opened so it seems that it should be used somehow.

Title: Re: Ralink RT2870 based USB Wireless N adapters (Ubuntu)
Post by: Mark Greaves (PCNetSpec) on July 13, 2011, 02:36:59 am

can you attach these 4 files:
/etc/Wireless/RT2870STA/RT2870STA.dat
/etc/network/interfaces
/etc/wpa_supplicant.conf
/etc/resolv.conf

The driver I'd go with is:
http://dl.dropbox.com/u/11876059/2011_0407_RT3070_RT3370_RT5370_RT5372_Linux_STA_V2.5.0.2_DPO.tar.bz2 (http://dl.dropbox.com/u/11876059/2011_0407_RT3070_RT3370_RT5370_RT5372_Linux_STA_V2.5.0.2_DPO.tar.bz2)
which is the latest driver that is *supposed* to support your card (148f:3070)

Writing a small script to bring the connection up automatically at starttup will be fairly easy.
or just adding
ifdown ra0
ifup ra0
to /etc/rc.local
should also run those 2 commands at startup
but let's just get it working first.

You also NEED to test it with an unsecured network as well, to check if it is JUST a WPA issue.

What does:

Code: [Select]

wpa_supplicant -Dwext -ira0 -c /etc/wpa_supplicant.conf -dd

output ?

Have you tested the connection WITHOUT security yet ? .. we need to know if it is a driver issue, or a wpa_supplicant issue.

[EDIT]

IF this is just a wpa_supplicant issue... which you can only be 100% sure of by trying it with an unsecured AP...

After reading on a few sites that people seemed to be having more luck with -
HAS_WPA_SUPPLICANT=y
and
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=n
set in config.mk before compiling and installing... you might want to give that a try.

then test the wpa_supplicant with:

Code: [Select]

wpa_supplicant -Dralink -ira0 -c /etc/wpa_supplicant.conf -dd

I'm sorry but this approach is not going to work for me.
Apparently one almost needs a university degree in network management before a simple wireless connection can be established.
All I know is that in Ubuntu Desktop version there's absolute no problem to establish a wireless WPA2 secured connection with that exact same wireless USB stick.

A few years ago I managed to create the wireless connection in Karmic Server version based upon an example and I'm still working with it. But in newer kernels it's definitely not working.
It must be somehow that wpa_supplicant stuff.

I've tried to test the connection against a non protected network like you've asked.
It's embarrassing to say but I failed. I even don't know how to adjust the relevant files in order to be able to connect to an insecure network. The network is detected but there's no association so I guess there must be something wrong with my configuration files.

I can only draw the conclusion that currently my knowledge about networks is absolute not sufficient to be able to do this and I don't have time to read more about it.
Can you provide me with configuration files, please?

Title: Re: Ralink RT2870 based USB Wireless N adapters (Ubuntu)
Post by: Mark Greaves (PCNetSpec) on July 14, 2011, 07:06:17 pm

Try these...

Run:

Code: [Select]

wpa_passphrase NetworkEssid your_passphrase

The output will be similar to -

Quote

network={
   ssid="NetworkEssid"
   #psk="your_passphrase"
   psk=559cb7c92c036b711ccdb40514c57b33c58372e7df912fc5f36a9f05a04d98ab

Obviously you need to replace NetworkEssid and your_passphrase

Now for the configs...

/etc/network/interfaces

Quote

auto ra0
iface ra0 inet static
address 10.0.0.19
netmask 255.255.255.0
gateway 10.0.0.140

}

Obviously you need to replace the bits in red with what you got from - wpa_passphrase NetworkEssid your_passphrase

/etc/resolv.conf

nameserver 10.0.0.19
nameserver 208.67.222.222
nameserver 208.67.220.220

Now try:
sudo ifdown ra0
then
sudo ifup ra0

If that doesn't work... post the output from:

Which might explain the system becoming unstable... can you attach another dmesg from the kernel and driver you are now using.

If I'm reading this correctly (but I may not be) it *may* suggest some sort of conflict between the wireless device/wpa_supplicant and the sound card... maybe in virtual memory... I'm trying to find out what "MainVirtualIF is ???

Post by: q7icmfm1x0h609c6xiok on July 16, 2011, 01:10:46 am

Thanks for investigating the problem so far. I really appreciate all the effort you make for this.

I've compared my configs with the ones in your post of July 14, 2011, 07:06:17 pm. There were some minor differences which I guess are not that important but nevertheless I corrected them:
* In my configs access point scanning mode set to 2 was still in etc/network/interfaces not in wpa_supplicant.conf.
* Proto in my wpa_supplicant.conf was set to RSN WPA instead of WPA2 WPA.

These modifications don't make any difference. Kernel 2.6.31 still works and kernel 2.6.35 does not.
In kernel 2.6.35 the interfaces name is not ra0 but wlan0 so I did: wpa_supplicant -Dwext -iwlan0 -c /etc/wpa_supplicant.conf -dd. Initially this didn't work (message about wpa_supplicant already active) but after issuing ifdown it did work.
The command seems to finish never so I stopped it with CTRL+C after some time. You can read the output in the attachment. If I read it correctly I understand from it that the driver does recognize the wireless network but that it fails when it comes to the security key.

Besides I've decided to get rid of all failed attempts and so I've removed all kernel images and kernel headers except for 2.6.31 which I do need as long as this matter is not solved. After that I've installed the latest kernel image and header of 2.6.35.
So the above test was performed on a pristine kernel without any additional drivers not even the one you've provided. We can probably try additional drivers in a subsequent step.

The observation you've posted in your post of July 15, 2011, 03:20:24 pm is quite interesting. Unfortunately I can't provide you with another dmesg output because I've removed that kernel earlier this week because of persisting crashes. So far 2.6.35 does not produce errors concerning paging errors.

Post by: Mark Greaves (PCNetSpec) on July 16, 2011, 02:12:56 am

From your wpa_supplicant output, it seems like it's an issue with the group cipher key length... maybe the key that you generated with wpa_passphrase is invalid.

Does your "passphrase" contain any strange characters such as a tilde (~) etc.

you might (just as a test) want to try entering the passphrase as a plain text key... so make /etc/wpa_supplicant.conf read:

Quote

ctrl_interface=/var/run/wpa_supplicant
ap_scan=2
#eapol_version=1
#fast_reauth=1

network={
ssid="NetworkEssid"
proto=WPA2 WPA
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
group=CCMP TKIP
psk="your_passphrase_in_plain_text_here"
}

be sure to include the "" quotation marks.

and now see what:

Code: [Select]

wpa_supplicant -Dwext -iwlan0 -c /etc/wpa_supplicant.conf -d

returns, and whether it connects.

let's use just one -d in the last command this time, to turn down the verbosity level... the last output was a bit longer than I expected and probably unnecessary ;)

Just as a matter of interest, what is the make/model of your router/access point ?

what is the output from:

Code: [Select]

iwlist wlan0 scanning

and do you NEED WPA2... I know your router/AP is mixed mode, but can't you just connect to it with WPA ? .. or am I misunderstanding your network layout ?

What I'm getting at is... couldn't you just drop WPA2 and CCMP altogether and just connect with WPA/TKIP ?

This seems to be the important part:

Quote

State: 4WAY_HANDSHAKE -> GROUP_HANDSHAKE
RSN: received GTK in pairwise handshake - hexdump(len=34): [REMOVED]
WPA: Unsupported CCMP Group Cipher key length 32 (32).
RSN: Failed to install GTK
RSN: Failed to configure GTK
wpa_driver_wext_deauthenticate

I'm reading up on the 4way handshake and GTK (group temporal key) now :o .. I'll post if I find anything.

Post by: q7icmfm1x0h609c6xiok on July 16, 2011, 06:27:33 pm

Just a quick reply for now.
Concerning WPA2: No, I do not insist on using WPA2 although it is safer. I have a rather old PC running Windows XP. Windows XP is supposed to handle WPA2 but it can't so that one connects with WPA too.
And that is merely the reason that my modem router is in mixed mode.
I can probably try what happens if I switch it to WPA or WPA2 only. I've found several claims that mixed mode means trouble with Ralink based adapters so it may be worth the effort to try it.

B.T.W.: Why doesn't it try WPA if WPA2 fails? if I am correct the config allows both types and the AP accepts both types.

Furthermore I still don't understand why the wireless USB adapter has no problems at all connecting to my network when I plug it into a laptop computer running the same Ubuntu version except it is the desktop version and besides with the 2.6.31 kernel on the server it also connects without problems. My guess is that there's nothing wrong with my wireless network, it is just a kernel/driver issue.
B.T.W.: I've brought the problem to the attention of the Ubuntu developers and their answer was that I should file a bugreport on Launchpad. Well, in Launchpad there are about 20 similar problems and virtually none of them has drawn the attention of the developers or is even triaged so I did not file a report after all.
The reality is simply that no one seems to know exactly what is happening with this type of adapters.

My passphrase does not contain strange characters. It is in hexadecimal form so it can't contain strange characters and the plaintext form is a mix of numbers and capitals.
And I know for sure it is correct because that old 2.6.31 kernel uses the same wpa_supplicant settings too and is still connecting without problems. The SSID does contain certain unusual characters but even that's not a problem for the 2.6.31 kernel.

My modem router is a FRITZ!Box Fon WLAN 7140 Annex A.

I didn't do any tests today. Probably tomorrow.

Title: Re: Ralink RT2870 based USB Wireless N adapters (Ubuntu)
Post by: Mark Greaves (PCNetSpec) on July 16, 2011, 09:05:01 pm

I agree... I would have expected it to fall back on WPA if WPA2 failed to connect, but it just appears to go into a loop of retrying WPA2.

I'm also as baffled as you as to why it works in the desktop edition but not the server edition... I do realise -
a) the kernels are slightly different... but wouldn't have expected the drivers (which are modules) to be any different.
b) NetworkManager handles the network connections slightly differently, but I'm unsure of the exact differences in the way the keys are generated, but I *do* know... after creating a WPA2 connection in NetworkManager and checking its settings in /etc/NetworkManager/system-connections .. NetworkManager appears to store the psk= as a plain text string of the passphrase, and NOT a long passkey hash. (but sets read/write permissions for owner root only [-rw------- 600])

I also know NetworkManager doesn't use the /etc/wpa_supplicant.conf or /etc/network/interfaces config files .. but it *does* use the wpa_supplicant service, and will start it even if it is disabled... NetworkManager gets its settings from /etc/NetworkManager/system-connections/<connection name>

So I would *guess* that it isn't a kernel issue, or a driver issue, and probably isn't a wpa_supplicant issue either... but more an issue of the way the network is brought up, and the way the passkey (psk=) is handed to the wpa_supplicant service.

Have you tried regenerating the long passkey hash from your passphrase, or are you just reusing the passkey hash that you previously had ?

It's a weird one this for sure.

I don't know whether you want to trust me with your passphrase and the passkey hash you are using so I can try them myself... if you are OK with that, send them to me either by email:
[email protected]
or in a Personal Message here.

As I suggested in my last post... I'd still suggest you try entering the psk= as a plain text string in /etc/wpa_supplicant.conf and see what happens.

I read on another forum that when using NetworkManager for a WPA/WPA2 connection, it asks for your passphrase, but after the first time you connect, the passphrase has changed to a passkey hash .. I'll look into this tonight and see if that's correct... if it is, maybe you can connect with a desktop edition, then copy the passkey hash NetworkManager generates to your servers wpa_supplicant.conf .. just an idea ;)

Hello,
I'm also having trouble getting my USB adapter (Sitecom WL-346) to work. I believe (I'm not absolutely sure) the appropriate driver for it is rt2870.
The problem is that the output of iwconfig only shows my loopback device.
By the way, I am using Ubuntu 11.04.

The output of lsusb:
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 002: ID 0df6:0051 Sitecom Europe B.V.
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Also the output of lsmod does not show a module with substring 'rt'.

When I unplug the adapter and replug it, and output the last lines of dmesg:
USB disconnect, address 2
new full speed USB device using uhci_hcd and address 3

I hope you guys can help.

@ Micheal

Hmm... I have a funny feeling your adapter may be loading as a ZeroCD device... can you post the full dmesg.

Code: [Select]

cd ~
dmesg >> dmesg.txt
zip dmesg.zip dmesg.txt

the attach the dmesg.zip file that you'll find in your home directory to your next post.

The reason... your mention of this line in dmesg:

Quote

new full speed USB device using uhci_hcd and address 3

and what I'm reading about another Sitecom device (Sitecom 300N Wireless WL-324) here:
http://ubuntuforums.org/showthread.php?t=1627423&page=2 (http://ubuntuforums.org/showthread.php?t=1627423&page=2)
in particular post #15 onwards.

So *maybe* this adapter also requires usb-modeswitch :o

I'm also wondering if the button changes it from ZeroCD to Wireless mode ??

run:

Code: [Select]

lsusb

press the button, and run it again... and see if the:
Bus 001 Device 002: ID 0df6:0051 Sitecom Europe B.V.
line has changed.

BTW, I'm guessing when you say "Sitecom WL-346" that's a typo... the Sitecom WL-346 is a router... the Sitecom WL-364 is a USB wireless adapter ;)

http://www.sitecom.com/wireless-network-usb-micro-adapter-300n/wl-364/p/788 (http://www.sitecom.com/wireless-network-usb-micro-adapter-300n/wl-364/p/788)

[EDIT]

Further info...

I've just unpacked the Windows drivers from the Sitecom website, and the HWID.ini file reads

(click to show/hide)

(look for the device ID string in red in the above spoiler... it's in the RT3070 section)

So it would *seem* as though you need the RT3070 driver... BUT... the latest Linux 3070 driver doesn't contain the device ID string for that adapter.

I can add the device ID string to the latest 3070 driver... then give you a link to the customised driver... then you can try it if you like ?
Up to you.

Hi Mark, thanks for responding.
You're correct about the typo, it is indeed the WL-364. :)

One of the problems was the outdated version of the rt2800usb driver.
In this commit the adapter is added: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-oneiric.git;a=commitdiff;h=87a3b89f34fb20f644b42fa57d579b1f2833fd4d (http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-oneiric.git;a=commitdiff;h=87a3b89f34fb20f644b42fa57d579b1f2833fd4d)

I've downloaded the complete (and most recent) compat source and compiled & installed everything.
At this time, the adapter is recognized (it shows up in iwconfig):

(click to show/hide)

But there are still problems, when I plug the adapter in, NetworkManager shows "device not ready (firmware missing)"
The output of dmesg:

Is the adapter recognised by:

Code: [Select]

sudo lshw -C network

and what driver does it say it's using ?

You could try the latest firmware snapshot from here:
http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git (http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git)

or the debian firmware-ralink_0.32_all.deb package from here (which appears to only be 3 days older):

Post by: Michael on July 18, 2011, 12:11:12 am

The adapter is not recognised if I type the aforesaid command (there is no output).
Installing either the deb file seems a good option. Though when I'm trying to install it, dpkg gives an error: "trying to overwrite /lib/firmware/rt2860.bin, which is also in package linux-firmware 1.52"
I'm looking into that.

Probably the best idea would be to manually backup all the files it's going to replace in /lib/firmware

ie.

Quote

rt73.bin
rt2561.bin
rt2561s.bin
rt2661.bin
rt2860.bin
rt2870.bin
rt3070.bin <--- now replaced by a symlink
rt3071.bin
rt3090.bin <--- symlink

then manually unpack the files from the .deb (using fileroller), and place them in /lib/firmware

Ok, I think it's success this time. There is a LED blinking, more info to be continued. :)

EDIT
I am now connected to my router which is WPA2 secured and IT WORKS! :)

Mark, thank you so much for helping me!! :)

@Mark:

Well, good to hear that it worked for Michael.

I guess I can add another success to this thread although it is not a complete success. The good news is that I managed to establish a connection with kernel 2.6.35.
The not so good news is that it still not works with WPA2. Based on our previous observations I've assumed that the fallback mechanism apparently fails for some reason so I've changed these lines of wpa_supplicant.conf:

proto=WPA2 WPA
pairwise=CCMP TKIP
group=CCMP TKIP

into these:

proto=WPA
pairwise=TKIP
group=TKIP

So now the driver is forced to work with WPA and that seems to work.

If I change it to this:

proto=WPA2
pairwise=CCMP
group=CCMP

thereby forcing WPA2 mode then the connection fails. However in this case scanning detects the AP (it gives the correct MAC-address) but fails to detect the SSID. I've a hunch that this might be due to the AP being hidden.

I've noticed a change in behavior that worries me a bit. In the old kernel the LED on the stick was blinking like mad. Now it blinks a few times and then it dims for several seconds and then blinks again a few times and this all happens in a random pattern. According to the log of the modem router the server does not disconnect so it appears to be a stable connection.

It does not seem to make any difference whether the psk is encrypted or in plain text.

Since we both have invested a lot of time in it already I'm determined to find out why it isn't working in WPA2 mode.

Are you willing to assist further in this process? May be we can achieve more results with the drivers we tried earlier or may be the approach with new firmware which you tried with Michael may work.

Anyway, I'm very happy with this success.

Mark, thank you so much for all the assistance and advice you gave me so far!

Yeh sure... I'm quite happy to keep looking for a WPA2 solution, I too hate being beaten ;)

Oddly enough after going through that with Michael, I was going to suggest a firmware update, and the latest drivers... maybe there is some kind of mismatch going on.

I also wonder if there is a later version of wpa_supplicant than the Maverick version... which version do you have:

Code: [Select]

wpa_supplicant -v

and for the Ubuntu package version:

Code: [Select]

sudo apt-get -v wpa_supplicant

Quote

I've a hunch that this might be due to the AP being hidden.

AFAIK the only way to be sure where the connection is failing would be to run:

Code: [Select]

wpa_supplicant -Dwext -iwlan0 -c /etc/wpa_supplicant.conf -d

and

Code: [Select]

iwlist wlan0 scanning

BTW, I wouldn't worry too much about the lights, I've got a PCMCIA card in an old laptop that flashes both the power and RX/TX lights very oddly in Linux (fine in Windows), but connects perfectly and has done for a year + .. both lights flash twice, then there's a gap, then they flash twice again... rinse and repeat.

I'll have a search for CCMP key length problems/solutions in the morning.

Excellent observation...

You mean a mismatch concerning what exactly?

That gives: v0.6.10

and for the Ubuntu package version:

sudo apt-get -v wpa_supplicant
That's not going to work as expected. Apt only displays information about itself.
According to aptitude the version in the repositories is v0.6.10-2 being the same version as the one installed.
According to the website of wpasupplicant (http://w1.fi/wpa_supplicant ([url]http://http://w1.fi/wpa_supplicant[/url])) there is a new version 0.7.3. but that one hasn't made it into the repository apparently.

So far the connection is still going strong without interruption. I guess this random blinking now represents the real activity while the earlier observed continuous blinking was in fact the odd behavior.
B.T.W.: in the older kernel there used to be frequent messages on the screen (but not in the logs) about a certain IOCTL error. That issue has stopped now either. Probably the connection in the old kernel was not so perfect after all.

I'll have a search for CCMP key length problems/solutions in the morning.

A (possible) mismatch between the newer drivers I was giving you links to, and the older firmware.

Sorry, I was after something like the "Version:" line from:

Code: [Select]

dpkg --status wpasupplicant

but it doesn't matter as there's no "easy" way to upgrade to 0.7.3 anyway... short of moving to Natty.

You suggested you thought it was something to do with the access point being hidden...What I meant by:

Code: [Select]
wpa_supplicant -Dwext -iwlan0 -c /etc/wpa_supplicant.conf -d

was that that it would be impossible AFAIK, to discover exactly what was causing the issue, other than to run that command... which *seems* to suggest that it is more to do with the key than the fact that the AP's SSID is hidden.

Did this result in new information?

Sorry, I've been a bit busy today... I'll post as soon as I find anything useful :)

[EDIT]

I'm finding quite a few references to WMM (Wireless Multimedia aka. Wireless QoS) causing WPA/WPA2 authentication issues... from what I gather this is enabled by default in the Fritz!Box 7140.

It might be worth turning it OFF in the router, and trying with WPA2 again... though this at first glance doesn't explain why it would connect on an earlier kernel... plenty of people were having a similar issue with Atheros wireless cards, they worked on earlier kernels but not on newer kernels... the workaround was to disable WMM (Wireless QoS) in the router.

See post #17 here:
https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/273336 (https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/273336)

OK that's an very old bug report... but FritBox's own website says WMM can cause connection issues:
http://www.avm.de/help/Sets/avme/en/002/hilfe_wlan_allgemein.html (http://www.avm.de/help/Sets/avme/en/002/hilfe_wlan_allgemein.html)
(see "Enable WMM" section towards the bottom)

So worth a try ?

Disabling WMM can affect VoIP. I do have a VoIP telephone connection.
I'll keep it in mind but I'm not going to try it yet. That LaunchPad thread links to another one with several so called solutions. I don't trust the solutions in that thread.
It boils down to "if one tries enough solutions it will somehow work" and the thread is outdated also.

My other laptop can connect using WPA2 to the same modem with the same USB stick so I don't believe it is a WMM related problem.
I want to investigate the firmware for now. Is it possible to find the version number of the firmware in use?

B.T.W.: I've found a message of wpa_supplicant in the daemon log stating:

failed to disable WPA in driver

It only happens when in WPA2 mode not in WPA mode.

Post by: Mark Greaves (PCNetSpec) on July 20, 2011, 06:23:31 pm

Oh, I agree about the thread... but... I take it your other system is using NetworkManager, which "somehow" seems to do the authentication differently.

I still think you should at least "try" it with WMM switched OFF... if it works, it *probably* means there is no other solution other than using WPA, or updating wpa_supplicant.

Title: Re: Ralink RT2870 based USB Wireless N adapters (Ubuntu)
Post by: q7icmfm1x0h609c6xiok on July 21, 2011, 04:06:35 pm

Indeed that other system is a regular desktop using NetworkManager.

Anyway, I did the test with WMM switched off on my server and it didn't make any difference.
Fortunately, I've finally found the factor that did make the difference. Switching the network to WPA2 mode only (so not mixed WPA + WPA2) seems to be the only way to get it working.
Apparently the driver, module or firmware or whatever else can't handle mixed mode and gets stuck. The older 2.6.31 kernel still handles mixed mode correctly.
I've done some tests with deliberately wrong settings. And if I set it to WPA2 + TKIP then I get more or less the same behavior as what the driver tries to do on a mixed mode network.

But there's still something strange with the 2.6.35 kernel. Somehow it insists on loading the RT2870STA module although you've pointed out that it is in fact more likely to use the RT3070STA because the stick identifies itself that way.

Now I've this in /etc/modprobe.d/blacklist.conf:
blacklist rt2800usb
blacklist rt2800lib
blacklist rt2x00usb
blacklist rt2x00lib

blacklist rt2870sta
#blacklist rt3070sta

So those are all the appropriate modules for the usb stick as far as I know and I should expect it to obey this and thus loading rt3070sta but interestingly it still loads rt2870sta.
If I blacklist rt3070sta too, so that all appropriate modules are blacklisted then it also loads rt2870sta.
I can't imagine that this behavior is hardcoded somewhere.

Title: Re: Ralink RT2870 based USB Wireless N adapters (Ubuntu)
Post by: Mark Greaves (PCNetSpec) on July 21, 2011, 04:24:42 pm

If you look in the recent firmware... rt3070 is just a symlink to rt2870, so I'm guessing it's similar with the more recent driver module.

So I guess if you force the loading of rt3070, it still loads rt2870... though I would have expected blacklisting BOTH would have killed the connection :o

So are you sayiing that if you:
blacklist rt2800usb
blacklist rt2800lib
blacklist rt2x00usb
blacklist rt2x00lib
blacklist rt2870sta
blacklist rt3070sta
the connection STILL comes up, and loads rt2870sta ? .. if so, what is the output from

Code: [Select]

lsmod

It may give a clue as to what is loading rt2870sta

Strange, and a little disappointing that the driver/kernel/firmware/wpa_supplicant can't handle a router set to mixed mode ::)

Thanks for letting us know that though... I'm sure someone will benefit from the info ;)

It would be interesting to know if this is specific to the combination of your wireless card and router, or if it is a more general problem with ANY card and ANY router set to mixed mode.

Are you now considering the issue unresolvable, or are you still experimenting ?

on another note...

Did you ever try setting 'HAS_WPA_SUPPLICANT=y' and 'HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=n' in config.mk before compiling... then bringing the network up with:

Code: [Select]

wpa_supplicant -Dralink -ira0 -c wpa_supplicant.conf -d

Code: [Select]

wpa_supplicant -Dralink -iwlan0 -c wpa_supplicant.conf -d

I'm still a bit bothered about why you're wlan0 rather than ra0 as a logical device... as far as I'm aware, the ralink drivers should give you ra0, ra1, etc.

Well, I've found multiple claims on the internet that Ralink adapters and mixed mode means trouble. As far as I can see these claims are quite valid.

You're most welcome.

It would be interesting to know if this is specific to the combination of your wireless card and router, or if it is a more general problem with ANY card and ANY router set to mixed mode.

Are you now considering the issue unresolvable, or are you still experimenting ?

Actually I consider the issue as solved.
When I started participating in this thread the issue was kernel 2.6.31 being able to connect to a WPA2 encrypted wireless network and kernel 2.6.35 not being able to connect at all.
Later we managed to get kernel 2.6.35 to connect to a WPA encrypted wireless network and now I've found that 2.6.35 is able to connect to a WPA2 encrypted network provided that the network is not mixed mode. The only remaining difference is now that kernel 2.6.31 can connect regardless if the network is mixed mode while 2.6.35 needs a WPA2 only network but I can live with that "limitation".

Although my issue has been solved now, we can still work more things out if you like. I know what should be in my configuration so I can always restore that.
Judging by the rocketing number of views of this thread I guess there are certainly people who can benefit from it.
The past weeks at least I did learn a lot about this subject...
This seems to be one of the very few threads that really gives answers about issues with Ralink adapters and I guess we still have some answers to give, so let's try it. ;D

on another note...

or
Code: [Select]
wpa_supplicant -Dralink -iwlan0 -c wpa_supplicant.conf -d
Well, not exactly. As I stated in Reply #83 on: July 16, 2011, 01:10:46 am, I've decided to get rid of all previous attempts so at that time I've reinstalled kernel 2.6.35 without touching kernel 2.6.31.
So the 2.6.35 kernel now works with the standard components that are available in the kernel itself. Currently I don't use any additional drivers or the drivers you've provided and therefore I did not need to compile anything.

I'm still a bit bothered about why you're wlan0 rather than ra0 as a logical device... as far as I'm aware, the ralink drivers should give you ra0, ra1, etc.

Yes, I don't like that part too but it is like it is. The only option I can think of is that I probably did leave something behind that has survived the reinstall of the 2.6.35 kernel and that is responsible for the changed device name, but I can't imagine what it would be.

@ q7icmfm1x0h609c6xiok

I'm going to guess rt2870sta is being loaded in initrd .. so if you updated it (now that rt2870sta is blacklisted in /etc/modprobe.d/blacklist.conf) that would stop it loading.

The problem with this is that there may not actually be a rt3070sta module.

What is the output from:

Code: [Select]

modinfo rt3070sta

Post by: q7icmfm1x0h609c6xiok on July 22, 2011, 04:36:07 pm

rt2870sta being load in initrd? That might be possible although I don't understand why because I did reinstall kernel 2.6.35 and so I rebuild the initrd I guess.
In my notes I read that I did a trick involving udev rules that was proposed on a website. It did it BEFORE the fresh reinstall of the kernel.
It involves this:

Create a new file /etc/udev/rules.d/network_drivers.rules with this line in it:
ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="148f", ATTR{idProduct}=="2870", RUN+="/sbin/modprobe -qba rt2870sta"

Create another new file /etc/modprobe.d/network_drivers.conf with this line in it:
install rt2870sta /sbin/modprobe –ignore-install rt2870sta $CMDLINE_OPTS; /bin/echo “148f 2870″ > /sys/bus/usb/drivers/rt2870/new_id

Then according to that website it should work. In my case it did not so I've removed those two files. I've tried it again and this time using 3070 in stead of 2870 but that didn't work either so I removed that too.

The only uncertainty is that the file /sys/bus/usb/drivers/rt2870/new_id is still present. I can't see its contents not even in superuser mode. I don't know if it is present in a fresh install so I didn't delete it.

modinfo rt3070sta indicates that the module isn't present.

Title: Re: Ralink RT2870 based USB Wireless N adapters (Ubuntu)
Post by: Mark Greaves (PCNetSpec) on July 22, 2011, 05:03:23 pm

Removing those 2 files should have automagically removed the entry from /sys/bus/usb/drivers/rt2870/new_id, as it appears it is "injected" at each boot only if those files are present.

[EDIT]
Hmm... just had an idea... if you've removed those files, is the driver now aware of your device ID string ?, or is rt2870sta somehow getting loaded for an "unknown" device as a default... in which case it would probably be unaware of the correct section of the firmware to load.

I know this is only slightly related:
https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/762987
but it does point out that different sections of the firmware are used for different "devices".

Adding the device ID to one of the installable drivers would be quite easy... and *should* leave you with ra0 rather than wlan0
[END EDIT]

But I'm still baffled where rt2870sta is being loaded, and why blacklisting has no effect... I know blacklist.conf will not stop drivers that are part of the kernel from being loaded, without updating initrd after blacklisting... so I'm afraid it's just a bit of an assumption on my part that the rt2870sta module is being loaded by something contained in initrd .. I'm not saying the module is itself "contained" in initrd, but your lsmod:

Quote

Module Size Used by
rt2870sta 406818 1
crc_ccitt 1351 1 rt2870sta

seems to be saying rt2870sta is being used by one other module.

As far as I can remember, every lsmod I've seen it before read:

Quote

Module Size Used by
rt2870sta 406818 0
crc_ccitt 1351 1 rt2870sta

OK, sometimes the rt2870sta module "size" varies depending on the version... but if I'm reading this correctly, something *appears* to be loading it as a dependency.

There definitely seems to be something rt2870 related in the kernel:

Code: [Select]

grep -i RT28 /boot/config-$(uname -r)*

output on my system (11.04 desktop)=

Quote

CONFIG_RT2800PCI=m
CONFIG_RT2800PCI_RT33XX=y
CONFIG_RT2800PCI_RT35XX=y
# CONFIG_RT2800PCI_RT53XX is not set
CONFIG_RT2800USB=m
CONFIG_RT2800USB_RT33XX=y
# CONFIG_RT2800USB_RT35XX is not set
CONFIG_RT2800USB_UNKNOWN=y <--- This maybe ?
CONFIG_RT2800_LIB=m
CONFIG_RT2860=m
CONFIG_RT2870=m

That said, if there is no rt3070sta module, trying to load it seems somewhat pointess... I'll keep digging ;)
(see the EDIT above - I'm wondering if this is firmware "section" issue... ie. it's using the wrong section)

Did any of that make sense to you, or should I try to re-order my line of thought ?

OK, this is a pure guess but see what you think anyway...

The parameter:
CONFIG_RT2800USB_UNKNOWN=y
says to the kernel, if an unknown RT2800USB device is encountered... load rt2800usb, but as that's blacklisted, rt2870(staging) is loaded instead as it's the most commonly used, and semi-works with most USB ralink devices.

So rt2870sta gets loaded before the blacklist.conf is read.

As it's an "UNKNOWN" device (ie. the device ID is missing), rt2870sta uses the firmware section for RT2870 chipped cards, rather than the RT3070 section... which "semi" works with RT3070 chips

As I said, that it TOTAL speculation on my part... but it *may* explain things

So what I'm thinking is if we add your device ID to the most recent driver from ralink in the RT3070 section, and use the most recent firmware....

It would be nice to know for SURE where rt2870sta is getting loaded, so I'm off to see if I can find a way to discover this ;)

Title: Re: Ralink RT2870 based USB Wireless N adapters (Ubuntu)

Well, I guess that's probably yes because it works in the older 2.6.31 which is the kernel that I did not experiment with and that one works pretty much out of the box.
Those two files don't exist in that older kernel.

I already said before that I mentioned the issue on launchpad and that the developers only suggested to file a bugreport...
In post #33 of that thread you can see that at that moment rt2870 was already loaded by something so it's not just an issue in kernel 2.6.35.

Adding the device ID to one of the installable drivers would be quite easy... and *should* leave you with ra0 rather than wlan0
[END EDIT]

I don't see any advantage in doing so. Post #10 in that launchpad thread reports also the name of interface as wlan0 so it happens more often.

crc_ccitt 1351 1 rt2870sta

OK, sometimes the rt2870sta module "size" varies depending on the version... but if I'm reading this correctly, something *appears* to be loading it as a dependency.

Yes I agree, it is loaded by something. B.T.W.: what does that size number mean? The rt2870sta module does not have that size (measured in bytes).

There definitely seems to be something rt2870 related in the kernel:
Code: [Select]
grep -i RT28 /boot/config-$(uname -r)*
output on my system (11.04 desktop)=
Quote
CONFIG_RT2800PCI=m
CONFIG_RT2800PCI_RT33XX=y
CONFIG_RT2800PCI_RT35XX=y
# CONFIG_RT2800PCI_RT53XX is not set
CONFIG_RT2800USB=m
CONFIG_RT2800USB_RT33XX=y
# CONFIG_RT2800USB_RT35XX is not set
CONFIG_RT2800USB_UNKNOWN=y <--- This maybe ?
CONFIG_RT2800_LIB=m
CONFIG_RT2860=m
CONFIG_RT2870=m

On my Ubuntu Server the output is pretty much identical, the only difference is that RT33 is substituted by RT30 in my output and the lines are in a slightly different order.

That said, if there is no rt3070sta module, trying to load it seems somewhat pointess... I'll keep digging ;)
(see the EDIT above - I'm wondering if this is firmware "section" issue... ie. it's using the wrong section)

Did any of that make sense to you, or should I try to re-order my line of thought ?

I can follow your line of thought. No need to reorder them. However I assume the thoughts are preliminary and that you're going to elaborate anyway. Therefore I've added a few of my observations.
It is an interesting subject, that's for sure.

OK, this is a pure guess but see what you think anyway...

The parameter:
CONFIG_RT2800USB_UNKNOWN=y
says to the kernel, if an unknown RT2800USB device is encountered... load rt2800usb, but as that's blacklisted, rt2870(staging) is loaded instead as it's the most commonly used, and semi-works with most USB ralink devices.

So rt2870sta gets loaded before the blacklist.conf is read.

Sounds about right.
I guess the "m" in some of the above lines stand for "manual" configuration (as opposed to automatic configuration; the "y" option)?

As it's an "UNKNOWN" device (ie. the device ID is missing), rt2870sta uses the firmware section for RT2870 chipped cards, rather than the RT3070 section... which "semi" works with RT3070 chips

As I said, that it TOTAL speculation on my part... but it *may* explain things

So what I'm thinking is if we add your device ID to the most recent driver from ralink in the RT3070 section, and use the most recent firmware....

The device ID (148F:3070) is already in the RT3070 section if I recall it correctly. I did a test with kernel 2.6.35 with the firmware mentioned in the launchpad at that moment and it did not work.

It would be nice to know for SURE where rt2870sta is getting loaded, so I'm off to see if I can find a way to discover this ;)

B.T.W.: the rt2870sta that is loading is indeed the version that belongs to the 2.6.35 kernel according to lsmod (so it's no leftover from the 2.6.31 kernel).

OK, but is that new_id entry always present? Because in my Ubuntu desktop version there isn't a sys/bus/drivers folder at all.

NO... only when the module is loaded... which is why they have to be "injected" every time (or compiled in).

You cannot *directly* add the device ID to the driver (using this method), as the driver isn't loaded yet... so you have to add the device ID to the USB subsystem, so when it's detected by that subsystem, it modprobes the driver... NOW you can add the device ID to the driver.

The first file effectively adds the device ID to the USB subsystem and if the device is then detected, modprobes rt2870sta

The second file then adds the device ID to the drivers "new_id" file (now that it has been created) so the *driver* is aware of the device.

If (on your desktop version) you force rt2870sta to load with:

Code: [Select]

sudo modprobe rt2870sta

(or plug the device in)
you'll see the *drivers* directory has now appeared ;) .. but that doesn't necessarily mean it knows what to do with the *device*.

Two thing have to happen when you plug a USB device in...
1) The USB subsystem has to be aware of the device ID so it knows what to do with the device, and what driver (if any) to load.
2) The driver (after being loaded by the USB subsystem) also has to be aware of the device ID so it know that it is supposed to handle it.

The above is a kind of simplified version... the USB subsystem can often take an educated guess as to the device type if it doesn't recognise the device ID

Non of this will survive a reboot if those files aren't present (or are empty), or unless the device ID has been compiled into the driver and added to the USB subsytem.

BTW, I'm assuming that was a typo... it should be /sys/bus/usb/drivers/rt2870

Quote

I don't see any advantage in doing so. Post #10 in that launchpad thread reports also the name of interface as wlan0 so it happens more often.

I'm not saying that there is an advantage to having the logical name ra0 (that's irrelevant) .. but I was under the impression that the ralink staging drivers used ra0 etc. as the logical name, but rt2800usb used wlan0 etc.

Post #10 in the launchpad thread is using the rt2800usb driver... NOT rt2870sta

So I still have a sneeking suspicion that rt2800usb is coming into play somewhere here... or that rt2870sta hasn't got the device ID string for your card compiled in.

Here's the important bit (if you want to skip the rest)
What I think *may* be happening is the USB subsystem *is* aware of the device ID (from a previous driver compile/install) so is loading rt2870sta... but the driver (because it's now the default version) *isn't* aware of the device ID, or is using the wrong section or wrong version of the firmware.

Quote

B.T.W.: what does that size number mean?

not sure... I'll see if I can find out.

[EDIT]
I haven't got a clue ??? .. but as you said it doesn't seem to have any relationship to the size of rt2870sta.ko, that's for sure... on my system

rt2870sta 450555 0
yet
rt2870sta.ko = 696712 bytes

I'm going to *guess* it's the "loaded" size... but it's a pure guess.
[END EDIT]

The device ID (148F:3070) is already in the RT3070 section if I recall it correctly. I did a test with kernel 2.6.35 with the firmware mentioned in the launchpad at that moment and it did not work.

Yes, but didn't *I* add that device ID to the most recent drivers before you downloaded them from my dropbox ? .. and even if I didn't, they were never tested with the "latest" firmware were they ? (I don't mean the firmware mentioned in that thread, I mean the very latest firmware)

ATM, I'm still trying to discover a way of being SURE where rt2870sta is being loaded...

Can you post the full output from:

Code: [Select]

modinfo rt2870sta

please.

and confirm that:

Code: [Select]

sudo lshw -C network

says the wireless device is using rt2870sta rather than rt2800usb

also, check to see if either of those are included in /etc/initramfs-tools/modules

BTW, I don't know if it was a typo... but those 2 lines you originally added had the wrong ID string anyway:

Quote

Create a new file /etc/udev/rules.d/network_drivers.rules with this line in it:
ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="148f", ATTR{idProduct}=="2870", RUN+="/sbin/modprobe -qba rt2870sta"

Create another new file /etc/modprobe.d/network_drivers.conf with this line in it:
install rt2870sta /sbin/modprobe –ignore-install rt2870sta $CMDLINE_OPTS; /bin/echo “148f 2870″ > /sys/bus/usb/drivers/rt2870/new_id

Isn't your device ID 148f:3070 ?

hi,

i'm on linux 10.04 and got the Intex wireless usb adapter model no: IT-ULC21. I have been trying to follow the instructions but I think I'm missing something..

I can't see the conflict is at the first pointer: here's the output I get when I enter : sudo lsmod | grep rt28

Moving on, I have a wireless icon in the top right corner that's not showing any network at all. In previous tests before doing this fresh install, I added rt2800usb to blacklist which resulted in no wireless network AT ALL.

Hi coolmac, welcome to the forum :)

Your device *should* be included in rt2800usb... can you post the output from these commands to confirm:

Code: [Select]

modinfo rt2800usb | grep 2070

also

modinfo rt2870sta | grep 2070

also

But I've also added the device ID (148f:2070) to this staging driver if you'd prefer to use that:

You got the second command wrong... it should have been:

modinfo rt2870sta | grep 2070

But it's unimportant... just try the drivers I gave you a link to.

You'll still have to blacklist rt2800usb

If i'm to go ahead with the instructions as per first post (http://linuxforums.org.uk/hardware-compatibility/ralink-rt2870-based-usb-wireless-n-adapters-(ubuntu)/msg4472/#msg4472) of this topic,

there's mention of installing "build-essential, and linux-headers-generic". How can I do this on a computer that is offline..my thinking is it needs internet?

Am I wrong? -how do I proceed from here?-

Yes, I'm afraid it *does* need an active internet connection to install those packages... can't you connect to the router with an ethernet cable ?

[EDIT]

If your 10.04 has never been updated, it may be best to remove the blacklisting of rt2800usb .. connect to a router with an ethernet cable .. run a complete system update .. then check if your wireless "just works", before installing the above mentioned driver ;)

I don't recall that and I assume you didn't because if you did so that would mean that my device ID is not recognized by rt3070sta in its original state.
Why do you think then that rt3070sta is better suitable for my device than rt2870sta?
To be honest I'd rather get rid of those staging drivers and it would be very nice if one of the Ubuntu standard drivers would work. In the earlier mentioned launchpad thread the developers claim that the RaLink drivers are sort of inferior to the standard drivers and that they will never make it out of staging. It seems that in Natty they are removed all together.

and even if I didn't, they were never tested with the "latest" firmware were they ? (I don't mean the firmware mentioned in that thread, I mean the very latest firmware)

I've tested them with firmware 1.53 which was the newest at that time and it didn't work. If there's a newer firmware then that might be better.

ATM, I'm still trying to discover a way of being SURE where rt2870sta is being loaded...

Can you post the full output from:

well, that is a very long list. I'll dump it in an attachment.

Isn't your device ID 148f:3070 ?

Yes, that's the device ID. But I said I've tried both possibilities. So it is not a typo. I just reproduced the lines from the first event because I had this info still available.

First, it's probably best to ignore rt3070sta (as a module), it doesn't really exist anymore (at least not in Natty), 3070 based cards use rt2870sta, but load the rt3070.bin firmware.

Can you confirm this by running:

Code: [Select]

modinfo rt3070sta

I'm expecting -

ERROR: modinfo: could not find module rt3070sta

I'd also go with the staging driver over rt2800usb, which IMHO aren't ready yet... indeed according to here:

maybe left over from an earlier driver installation attempt... which would explain rt2870sta loading even if it's blacklisted.

but I'm still baffled why it's wlan0, which suggests it's using rt2800usb ???

Which driver is being used on the desktop edition ?

Is rt2870sta still blacklisted ?

OK, here's what I'd do (but it's up to you whether you want to mess with a working system)

1) Download these drivers:
http://dl.dropbox.com/u/11876059/q7icmfm%20-2011_0407_RT3070_RT3370_RT5370_RT5372_Linux_STA_V2.5.0.2_DPO.tar.bz2 (http://dl.dropbox.com/u/11876059/q7icmfm%20-2011_0407_RT3070_RT3370_RT5370_RT5372_Linux_STA_V2.5.0.2_DPO.tar.bz2)
unpack them, cd into the direectory, change to root with sudo su, then run make && make install

2) Make sure the ONLY thing that is blacklisted is rt2800usb .. ie. un-blacklist -
rt2800lib
rt2x00usb
rt2x00lib
rt2870sta
rt3070sta

3) Reboot and test the card (or ifdown wlan0 then modprobe -r rt2870sta then modprobe rt2870sta then ifup ra0)

4) if necessary, replace the firmware in /lib/firmware with the ones contained in the latest firmware from one of these Debian mirrors:
http://packages.debian.org/sid/all/firmware-ralink/download (http://packages.debian.org/sid/all/firmware-ralink/download)

Be aware - You cannot install this as you normally would a .deb... it's best to backup the files you are going to replace in /lib/firmware

ie.

Quote

rt73.bin
rt2561.bin
rt2561s.bin
rt2661.bin
rt2860.bin
rt2870.bin
rt3070.bin <--- now replaced by a symlink
rt3071.bin
rt3090.bin <--- symlink

then manually unpack the files from the .deb (using fileroller), and place them in /lib/firmware

Then I would expect

Code: [Select]

iwconfig

to return something like -

Quote

or similar.

If it *does* change to ra0, remember you'll have to change it in /etc/network/interfaces

But as I said, it's up to you if you want to mess with the wireless drivers/firmware, whilst it is (more or less) working ;)

I managed to get an ethernet connection and ran sudo apt-get update..

I followed the instructions...delisted the blacklisted rt2800usb then restarted then ran sudo sh -c 'echo rt2870sta >> /etc/modules'. Still no connection or any wireless connection.

i proceeded to blacklist it and installed the drivers then ran sudo make && make install. Restarted and still nothing shows. I then decided I'd delist the rt2800usb then see what happens. Wireless shows up but it doesn't recognize any networks. which is wrong because the wireless is up and running. I then blacklisted rt2800usb and decided I'd come here again.

I know this will be very long, but can you send the output from:

Code: [Select]

lsusb -v

and

Code: [Select]

lsmod

and

Code: [Select]

modinfo rt2870sta

and

Code: [Select]

modinfo rt3070sta

I know you've already answered some of these, but I'm a bit baffled as to why the device is no longer being discovered at all... it was plugged in wasn't it ?

and you did send the WHOLE output from:

Code: [Select]

sudo lshw -C network

didn't you ?

First, it's probably best to ignore rt3070sta (as a module), it doesn't really exist anymore (at least not in Natty), 3070 based cards use rt2870sta, but load the rt3070.bin firmware.

Can you confirm this by running:
Code: [Select]
modinfo rt3070sta
I'm expecting -
Quote
ERROR: modinfo: could not find module rt3070sta

I've tested this on the desktop edition which is Natty and you're spot on.

I'd also go with the staging driver over rt2800usb, which IMHO aren't ready yet... indeed according to here:

Current problems:

* No TX during first minute after association
* Broken Hardware encryption

Well, I guess I can confirm that broken hardware encryption. Right now on the laptop (Natty desktop version) I have a wireless connection via the second RT3070 usb stick and it uses the rt2800usb driver. Every now and then it looses the connection for a short while...

There is something very strange going on with your drivers... rt2870sta *does* have the device ID...

From modinfo rt2870sta
Quote
alias: usb:v148Fp3070d*dc*dsc*dp*ic*isc*ip*

maybe left over from an earlier driver installation attempt... which would explain rt2870sta loading even if it's blacklisted.

but I'm still baffled why it's wlan0, which suggests it's using rt2800usb ???

Which driver is being used on the desktop edition ?

The desktop uses driver rt2800usb and detects the interface as wlan1 (because wlan0 is taken by the internal wireless network card which is made by Realtek)

Is rt2870sta still blacklisted ?

On the server it is still blacklisted.

OK, here's what I'd do (but it's up to you whether you want to mess with a working system)

1) Download these drivers:
http://dl.dropbox.com/u/11876059/q7icmfm%20-2011_0407_RT3070_RT3370_RT5370_RT5372_Linux_STA_V2.5.0.2_DPO.tar.bz2 ([url]http://http://dl.dropbox.com/u/11876059/q7icmfm%20-2011_0407_RT3070_RT3370_RT5370_RT5372_Linux_STA_V2.5.0.2_DPO.tar.bz2[/url])
unpack them, cd into the direectory, change to root with sudo su, then run make && make install

2) Make sure the ONLY thing that is blacklisted is rt2800usb .. ie. un-blacklist -
rt2800lib
rt2x00usb
rt2x00lib
rt2870sta
rt3070sta

3) Reboot and test the card (or ifdown wlan0 then modprobe -r rt2870sta then modprobe rt2870sta then ifup ra0)

4) if necessary, replace the firmware in /lib/firmware with the ones contained in the latest firmware from one of these Debian mirrors:
http://packages.debian.org/sid/all/firmware-ralink/download ([url]http://http://packages.debian.org/sid/all/firmware-ralink/download[/url])

Be aware - You cannot install this as you normally would a .deb... it's best to backup the files you are going to replace in /lib/firmware

ie.

Quote
rt73.bin
rt2561.bin
rt2561s.bin
rt2661.bin
rt2860.bin
rt2870.bin
rt3070.bin <--- now replaced by a symlink
rt3071.bin
rt3090.bin <--- symlink

then manually unpack the files from the .deb (using fileroller), and place them in /lib/firmware

Then I would expect
Code: [Select]
iwconfig
to return something like -

Quote
ra0 RT2870 Wireless ESSID:"" Nickname:"RT2870STA"
Mode:Managed Frequency=2.412 GHz Access Point:
Bit Rate=54 Mb/s
RTS thr:off Fragment thr:off
Link Quality=100/100 Signal level:-29 dBm Noise level:-71 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

or similar.

If it *does* change to ra0, remember you'll have to change it in /etc/network/interfaces

But as I said, it's up to you if you want to mess with the wireless drivers/firmware, whilst it is (more or less) working ;)

FYI: I've checked it on the desktop version and the files you indicate as symlinks are no symlinks but just plain files.
The only mystery remaining is why it uses an unusual interface name but it seems we can't answer that for now.
Furthermore the wireless connection is WPA2 encrypted and it works on its maximum speed. I guess there's nothing to gain right now by messing with the drivers and/or firmware. I can only loose now by breaking it again so I think it is wise that I'm not going to mess with the files on the server until I need to.
Besides I've new priorities. Based upon this success I've decided to connect all of my peripheral devices to the server. That went very well but I've some issues with a rather old flatbedscanner. So I'm going to search for a thread on this forum to get some clues about that.

I've tested the procedure above with my ubuntu desktop and the second RT3070 usb stick and guess what:
Even with rt2800usb blacklisted and rt2870 modprobed it STILL loads rt2800usb.
Weird...
I now have two separate computers and two different ubuntu versions (Server: Maverick; Desktop: Natty) that both completely seem to ignore that blacklist file. There's something strange going on with either blacklisting or that rt2800 driver.

yet:

If so, I agree, VERY weird ???

Yes, I did say that, but it turns out to be WRONG.
Apparently something had been screwed up. Now it does respect the blacklisting.

However there are other errors. ifup gives an error about wlan1=wlan1 or something like that.
I can't remember it exactly and I don't have the second usb stick available right now.

I am a complete novice at Ubuntu and recently purchased a Linksys AE1000 wireless adapter for my desktop pc.
I have Ubuntu 10.4 I think running under VMware.

Can someone provide me with exact instructions on how to activate this adapter in Ubuntu? Don't assume I know anything.

I would be very grateful for some help.

Hi pevers1, welcome to the forum :)

I'm not 100% sure how VMware handles USB devices... ie. whether it just passes through the hosts connection, or if you need to have the Linux drivers installed... Which OS is hosting VMware ? .. and does the adapter work in the host OS ?

I'll download VMware player lter and check, but for now can you (in Ubuntu) open a terminal and enter:

Code: [Select]

lsusb

hit enter, and post the output.

also post the output from:

Code: [Select]

sudo lshw -C network

Remember, Linux commands ARE case sensitive.

Now I'm absolutely done with that (***) Ubuntu. >:(

I've installed it on a third computer. Exact same install CD as before (ubuntu 10.04), exact same USB wireless dongle (148f:3070).
No go.

So now I've:
- a working laptop (wireless works right out of the box)
- a working server (wireless works after a lot of messing around and absolutely no clue why it works).
- a not working regular desktop. Even trying all solutions mentioned here do not solve the problems.

There are a lot of solutions here but probably the most important one is not mentioned being:

Ubuntu's hardware detection is terrible, especially the wireless department.
Each install is different from another and each new release contains more and more errors.

If one wants to work wireless then better say goodbye to ubuntu.
Ubuntu for humans?! I don't think so. At least not "regular" humans ;)

I'm going to ditch it anyway (the version on the not working desktop). Because of a major bug in grub2 in 11.04 (importance: undecided [ :-\ ] according to the developers) it won't boot anymore.

Post by: BkS on September 05, 2011, 12:34:22 pm

Well I've install Ubuntu on 3 different laptop in the past year, and not once have I had a problem with wireless detection. So I don't see how Ubuntu's hardware detection is so bad.

Title: Re: Ralink RT2870 based USB Wireless N adapters (Ubuntu)
Post by: Mark Greaves (PCNetSpec) on September 05, 2011, 12:48:17 pm

Without more evidence than an obscure USB-->Parallel adapter cable (which you state doesn't work properly in Windows) and a single generic Wireless device, I'm afraid I'm going to have to agree with BkS on this one.

And when you stack the price of a new PCI Parallel port card and a new wireless adapter, against the price of Windows + AV + Office +...... ;)

Sorry if this sounds like I'm "having a go", I'm not... but I've found Ubuntu hardware detection and driver support pretty darn good... though I suppose there *could* be an element of luck involved :)

Title: Re: Ralink RT2870 based USB Wireless N adapters (Ubuntu)
Post by: q7icmfm1x0h609c6xiok on September 05, 2011, 05:49:43 pm

What has the usb parallel adapter issue to do with this? ???
Anyway, the wireless device identifies itself as 148f:3070 so I should think it uses RT3070sta.
Well wrong; that driver does not exist anymore so it goes for RT2870sta on the server computer. But only after a lot messing around.

On my laptop is uses rt2800usb driver and it does not need any editing or whatsoever. it is not even necessary to blacklist drivers.

On my rather old desktop (that might be a problem concerning the type of usb ports), it tries to use rt2870sta en rt2800usb simultaneously, so one needs to be blacklisted.
I chose to use rt2870sta then ubuntu states there are wireless networks. It does not tell which and it can't connect to the correct one.
So again: hardware detection is not exactly that bad but it is inaccurate in relating the device to a suitable driver.

But like I said I ditched Ubuntu on the desktop because it has a grub2 problem, but I'm going to reinstall a somewhat older version.
So the server has nothing not much to do with this.
FYI: I know that suggestion about a PCI parallel port but unfortunately that won't work.
It is a special computer. It has approximately the size of a old 5,25 inch floppy and the height if I may call it like that, is about 1 inch. So it is physically impossible to insert a new card.
But I must say this mini computer works quite good.

I'll go with the observation of Mark. Probably there's an element of luck involved.
I';ve had a few cases where things didn't work on the first few attempts but after some time doing nothing to it things start to work. It might be luck, or new insights or probably new updates. I don't know.
All I know is that a problem is rarely a permanent problem.
And I do like ubuntu better than windows anyway ;D

Post by: Mark Greaves (PCNetSpec) on September 05, 2011, 05:56:17 pm

Can you provide more info on the GRUB2 problem please... I've not heard of it :o .. though the Reinstalling GRUB 1.99 in Ubuntu 11.04 from LiveCD - Command change (http://linuxforums.org.uk/ubuntu/reinstalling-grub-1-99-in-ubuntu-11-04-from-livecd-command-change/) page on this forum does seem to be getting a LOT of hits.
(I've never understood the whole GRUB2/Linux naming convention thing, where 0.x -> 0.99 is version 1, and 1.0 -> 1.99 is version 2, but there you go)

Or do you mean that particular PC doesn't like GRUB2 ? .. any ideas why ? .. is it a fakeRAID issue ?

I'll agree that where *new* hardware is concerned (and still sadly with some wireless devices in particular) Linux sometimes lags behind Windows as far as drivers are concerned, but I see this as the manufacturers that are at fault in not providing current working proprietary drivers, or at least open sourcing them... not that that helps in any way ::)

Sadly, I suppose the moral of this story is that *sometimes* you need to do a little more homework with Linux and device drivers... but as you say they usually catch up, or the issue is solvable... again, not that that's always a help to everyone, or if you already own the hardware.

BTW, the RTXXXXSTA drivers are proprietary closed source drivers from Ralink, so are AFAIK legally un-modifiable, so somewhat of a manufacturer created issue again... they sell the chips to generic card manufacturers, then take forever to add the ID's to their drivers which can be a royal pain for users because the Linux devs (AFAIK) can't add them. ;)
but as you say the open source rt2800usb drivers are coming along in leaps and bounds, and getting better daily, so there's still hope for the near future :)

RT3070STA was "supposed" to have been absorbed into RT2870STA, but again how well that works is down to Ralink.

Do you think it may be worth giving Debian (testing or unstable) a test drive ? .. they flatly refuse to use proprietary drivers, so *may* put more effort into making sure the open source drivers work, and are upstream of Ubuntu anyway.

With rt2800usb Internet was very slow and I got disconnected frequently.

Old rt2800 included with ubuntu 11.04 was working fine except crashing once or twice a week, which make me look for a new driver.

OK, first thing to try... get firmware 1.53 from here:
https://launchpad.net/ubuntu/oneiric/+source/linux-firmware/1.53/+files/linux-firmware_1.53.tar.gz (https://launchpad.net/ubuntu/oneiric/+source/linux-firmware/1.53/+files/linux-firmware_1.53.tar.gz)

and see if that works with rt2870sta

meanwhile, is anything returned for:

Code: [Select]

modinfo rt2800usb

at all ?

The reason I ask is that your card is listed as working in Debian using rt2800usb, the latest firmware, and a kernel that has the device ID's included in rt2800usb

http://wiki.debian.org/rt2800usb (http://wiki.debian.org/rt2800usb)

Just to be sure I've got the correct ID's can you also post the output from:

Code: [Select]

lsusb

(I know it's on the Ubuntu forum dut I want to be sure)

The device ID's *ARE* included in the kernel I'm running (3.1.0-0301rc4-generic), and whilst you are answering the above, I'll try booting into other kernels to find which one they first appeared in.

BTW, we *may* need to replace the rt2870.bin firmware from the Debian firmware package, which is slightly newer than even Ubuntu's 1.53, but we'll try that later.

Sorry for the mega n00b question but how do I update the firmware once I've downloaded it? It seems like I don't want to go into synaptic and just deinstall the previous stuff. But I can do that.

Here is lsusb:

Code: [Select]

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Everything starting in Transcend Information or Linksys is the same card. If I unplug, all three disappear. Yes, the product and vendor addresses you gave me seem correct. If that Debian package is correct, wouldn't that mean that rt3070 is the correct driver?

I haven't heard of ANYBODY on the web getting AM10 to work in linux. As far as I know, I am #1 (in many ways, not all of them flattering).

OK easiest way...

Code: [Select]

sudo cp -rv /lib/firmware /lib/firmware-old

then

Code: [Select]

sudo cp -rv /usr/share/doc/linux-firmware /usr/share/doc/linux-firmware-old

OK that's the current firmware backed up (just in case)

now download this (even newer 1.54) .deb:
https://launchpad.net/~thomas-creutz/+archive/linux-firmware/+build/2556299/+files/linux-firmware_1.54%7Eppa1_all.deb

and just double-click it to install... when Ubuntu Software Centre opens, just click the Upgrade button.

Sorry, got a bit busy there for a while... I'll go check the earlier kernels now :)

Thanks, I've now updated the firmware. Nothing magical happened with regards to the rt2870 driver magically working when plugged in. But I'll try updating then using rt2800usb tomorrow.

Thanks for the instructions. (I always forget how easy debian packages are - software center's totally got my back - I'm always imagining I'll be pounding something out in the black terminal screen).

Ok, I'm going to try rt2800USB - I doubt I'll have much success.

Also, if I want rt2800usb to have an eye out for 13b1:0031 (FYI I now have all the vendor and product IDs memorized, how scary is that), how do I do that?

When I added 13b1:0031 to rt2870sta I had to take the original - what is that, a binary, is it source code? - anyway, and then I added that to the things it watches out for. I have no idea how to do that for rt2800usb. Forgive the n00b question, but I couldn't find source code for it. It must come off the Ralink site or something - I was googling for half an hour and clearly if it's obvious I missed it.

Also, I was also going to point out that you didn't answer my question above about - how do you know which version of rt.... to use? rt2870, rt2800usb, rt3572, rt3070 - I am not at all sure what the difference is. But I really appreciate the help.

I'll report back if I have any success, but I doubt it. I'll just edit this post so as not to create an even bigger thread.\

OK, it will be interesting to see what happens when you blacklist rt2870sta and modprobe rt2800usb... as rt2800usb on your kernel doesn't have the correct ID's built in.

After trying that, there are a couple of options...

a) try a different STA driver... your adapter seems to be an rt3072
Now though I can find NO info for your particular card online, a few people usin a SWEEX card based on the rt3072 seem to have had luck adding the device ID's to the rt3070 drivers... so may be worth a shot.

b) move to a later kernel... problem with this is that the correct device ID's aren't in the 2.6.39 kernel either, which means moving to kernel >= 3.0 (I only know for sure they are in 3.1), vut this *may* introduce other problems, such as having to reload your graphics drivers... 3.1 works fine for me, but there are NO guarantees it will work (without issue) for you.

That said, you should still be able to boot the old kernel, if 3.1 gives you problems.

OR

You could just wait for Ubuntu 11.10, which will use kernel >=3.0 by default.

AFAIK, you can't... rt2800usb is built into the kernel, so without downloading the kernel source, patching it, and recompiling it, there is no way to add the ID's (at least that I'm aware of).

But you never know your luck... it *may* work anyway, as long as rt2800usb is loaded (and rt2870sta NOT loaded)

As I said Ubuntu 11.10 will use (at least) kernel 3.0 which *may* contain the correct ID's by default... even if it doesn't, upgrading the kernel to 3.1 (which definitely has the ID's) should be less risky in 11.10... so it *may* just be best to wait.

But as ever, the choice of which way you want to go is up to you.

Well, I'm running rt2800usb - I tried it earlier, it officially wasn't working. Unlike before with rt2870, network manager wasn't even picking up that a wireless device had been plugged or unplugged (at least I assume it's network-manager that creates the notifications when you gain and lose internet access. I'm going to try a udev rule to see if I can get that to work.

Do you think it would help to add a line here:

Code: [Select]

gksudo gedit /etc/udev/rules.d/70-persistent-net.rules

Code: [Select]

ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="13b1", ATTR{idProduct}=="0031", RUN+="/sbin/modprobe -qba rt2800usb"

Already my udev rules have:

Code: [Select]

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="68:7f:74:e3:f6:4b", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="ra*", NAME="ra0"

I'm not sure what, if anything this line that is there accomplishing. But maybe I could call a driver.

Let me respond to your previous response a bit more:

OK, it will be interesting to see what happens when you blacklist rt2870sta and modprobe rt2800usb... as rt2800usb on your kernel doesn't have the correct ID's built in.

After trying that, there are a couple of options...

a) try a different STA driver... your adapter seems to be an rt3072
Now though I can find NO info for your particular card online, a few people usin a SWEEX card based on the rt3072 seem to have had luck adding the device ID's to the rt3070 drivers... so may be worth a shot.

b) move to a later kernel... problem with this is that the correct device ID's aren't in the 2.6.39 kernel either, which means moving to kernel >= 3.0 (I only know for sure they are in 3.1), vut this *may* introduce other problems, such as having to reload your graphics drivers... 3.1 works fine for me, but there are NO guarantees it will work (without issue) for you.

That said, you should still be able to boot the old kernel, if 3.1 gives you problems.

OR

You could just wait for Ubuntu 11.10, which will use kernel >=3.0 by default.

When you talk about kernel 2.6.39 - are you talking about of ubuntu? And what is kernel 3.0 - is that the version of Ubuntu that's coming out next month?

I'm going to try rt3572 and after that, rt3070, so we'll see what happens. The old rotating driver trick. Do you think SWEEX is worth a shot? Never heard of it - if you have the link where you're reading, that may be helpful.

Post by: Mark Greaves (PCNetSpec) on September 20, 2011, 06:33:15 pm

OK, try this...

Unplug the device, then run:

Code: [Select]

sudo modrope -r rt2870sta
sudo modprobe rt2800usb
sudo -s
echo 13B1 0031 > /sys/bus/usb/drivers/rt2800usb/new_id
exit

then plug in your device, and see if it works.

If it does, we'll add it permanently.

The reason I used a capital B in 13B1 is that's the way it's listed in rt2800usb from kernel 3.1 .. though I'm fairly sure case doesn't matter.

When you talk about kernel 2.6.39 - are you talking about of ubuntu? And what is kernel 3.0 - is that the version of Ubuntu that's coming out next month?

No... think of the kernel as the core of OS .. at the moment, Ubuntu 11.04 is using kernel 2.6.38 by default, but it is easy to upgrade that to 2.6.39

The kernel devolopers have changed the kernel naming convention after 2.6.39 to 3.0. 3.1 etc.

The next version of Ubuntu (11.10) will use kernel 3.0 (or maybe 3.1)

rt2800usb is part of the kernel (not a separate module like the STA drivers)... so you can't add the ID's before compiling the driver, you'd have to compile the whole kernel .. but there is a way :)

The kernel IS Linux .. Ubuntu is a Linux "Distribution", which consists of the Linux kernel, the GNU tool chain, and a lot of applications, all put together as a "Distribution".

If you want to know more about the kernels job... see here:
http://en.wikipedia.org/wiki/Kernel_%28computing%29 (http://en.wikipedia.org/wiki/Kernel_%28computing%29)
and

Do you think SWEEX is worth a shot?

I think (but i'd have to check) the people who had cards made by SWEEX that used the same chip as yours (rt3072) were using the
2011_0407_RT3070_RT3370_RT5370_RT5372_Linux_STA_V2.5.0.2_DPO
driver, and adding their ID's to the 3070 section.

Lost the damn link though... but I'll see if I can find it again.

Thanks Mark,

I really appreciate the fix you provided which enabled me (once again) to compile a driver for my RT2870 based wireless USB adapter (DWA140) on kernels >= 2.6.35.
I'm running Mepis 11 which has the 2.6.36 kernel.
Of course I searched and searched the net, begged Ralinktech to provide a newer source package that would support kernels >= 2.6.35. No dice..... :-[
In the end I decided to installed the then current Debian 2.6.32 kernel and compiled/checkinstalled a .deb for that kernel. All went well of course...
Pure chance led me here and there it was: renamed usb functions as of 2.6.35 + a fix that enabled successfully compiling for newer kernels.

I'm happy to report that my DWA140 is happily humming along in M11 with its default Mepis kernel 2.6.36....:-)

Once again, thanks,

Ko

@Mark:

On the issue of "somehow rt2870sta loads, despite blacklisting":
Have you considered that (since kernel 2.6.30?) the kernel itself provides a number of experimental ('staging') wireless drivers - including one for rt2870sta?
See the attached screenshot (found 3 instances of rt2870sta,ko -- one in the 'staging' folder. And that one has been proven worthless _to me_ in the past.
Normally I used to either rename it or replace it there with the newer rt2870sta.ko from self-compiling/installing the driver.
Somehow I forgot to do that yesterday, but my wireless still works OK, so it may not be necessary any longer
The relevant output from lsmod shows: 'rt2870sta 448934 1' as module-size.

I also use "checkinstall" instead of "make install" during compilation. That also provides a .deb package...:-)

AFAIK the included staging rt2870sta.ko is a loadable kernel object (module), and not compiled into the kernel itself .. so I would have expected it to be blacklistable .. but I no longer have an rt2870 based adapter to test it on, so who knows.

I'm pretty certain "staging" drivers are NOT merged into the mainline kernel and are stand-alone drivers, but could be wrong :o

Searching for and renaming the .ko may have been a good idea though :)

You're right that the staging drivers are loadable kernel objects.
I didn't imply that is was compiled into the kernel. Just that they're provided at kernel installation and loaded as experimental driver at startup...

Mark, it seems you are very patient to help noobs, well thats me... I need help. I just purchased a Rosewill RNXN600UBE and I need to get the drivers installed on 3 different machines all running Ubuntu 11.10. I noticed the driver for this from Rosewill's website is labeled as the Ralink RT3572, but in the config file it says RT2870 for everything.

I went to Ralink's website and noticed the RT3572 and the RT2870 drivers for download, to me they look like the same thing. maybe this is my problem? I dont know. (maybe they are different because its a dual band adapter?)

I followed all the instructions and everything went fine, I even used your uploaded build for make install. it seems to have installed, except when I do the modprobe command it seems to do nothing, it takes a second then finishes. It does not make an ra0 network device. Iwconfig shows nothing, and lsmod shows the driver there but nothing is happening.

lsusb says this "Bus 002 Device 005: ID 148f:3572 Ralink Technology, Corp. RT3572 Wireless Adapter"
lsmod says this "rt2870sta 570803 0 " this is the only rt28 driver.

Did I fucked up by installing the RT2870 driver compared to the RT3572? Did my installation fail? What do I do? Please help me Mark, I really reallllllly would appreciate it. I Tip my hat to your patience, and Thank You in advance.

OK first of all you'll need the 2011_0427_RT3572_Linux_STA_v2.5.0.0.DPO.bz2 driver from the Ralink website -

Go to this page:
http://www.ralinktech.com/en/04_support/license.php?sn=5017# (http://www.ralinktech.com/en/04_support/license.php?sn=5017#)

and fill in your name and email, then click Accept .. the file will then download
(you can enter ANY name and email .. it's not checked)

Unpack the driver (I needed to do it twice for some reason)

Then compile/install as usual

IIRC the 2.5.0.0 driver compiles OK in 11.10, if it doesn't let me know.

I've checked it and it DOES contain the ID strings for your card (148f:3572).

If you don't know how to compie/install, just ask :)

The unpacked drivers may *look* like rt2870 as they contain files with that name .. but they ARE different.

If you've already compiled and installed (ie. already run the make && sudo make install) ..

Log off, then on again .. then unplug the USB adapter .. wait ten seconds .. replug it .. and send the output from:

[EDIT]

See my next posting first

[END EDIT]

First try

Code: [Select]

sudo modprobe -r rt2870sta

then

Code: [Select]

sudo modprobe rt2870sta

If that doesn't work, try blacklisting rt2870sta .. then rebooting

Did you make the edits to the driver for WPA support before compiling and installing ?

Post by: Mark Greaves (PCNetSpec) on March 02, 2012, 12:27:59 am

OK, looks like you were right, rt2870sta IS conflicting with the rt3572sta module..
(Please see the IMPORTANT note at the bottom first)

You'll need to blacklist the rt2870sta module, so open a terminal and run:

Code: [Select]

sudo gedit /etc/modprobe.d/blacklist.conf

add a new line that reads

blacklist rt2870sta

Save the file and exit.

Now run:

Code: [Select]

sudo modprobe -r rt2870sta

then

Code: [Select]

sudo modprobe rt3572sta

If it works, but doesn't survive a reboot, run:

Code: [Select]

sudo sh -c 'echo rt3572sta >> /etc/modules'

and reboot.

THIS IS IMPORTANT (if you use WPA(2) encryption) ..

If you DIDN'T make the edits to the Ralink driver for WPA(2) support BEFORE compiling and installing.

Download these drivers from my dropbox, they are allready edited to give WPA(2) support:
http://dl.dropbox.com/u/11876059/2011_0427_RT3572_Linux_STA_v2.5.0.0.DPO.tar.bz2 (http://dl.dropbox.com/u/11876059/2011_0427_RT3572_Linux_STA_v2.5.0.0.DPO.tar.bz2)

then compile and install them.

Honestly Mark, You have no idea how grateful I am for your help. I had to go out and I am now back. Ill do everything you said before later, but for now I installed the driver the laptop, except.... It will not connect to my network and consistently tries to reconnect but never gets there. with Airodump-ng it wont pick up any networks even though its in monitor mode. Maybe you can help with that? I do have a WPA network and I did make the WPA config change. The computer recognizesthe card fine and "finds" networks but wont connect and like I said, It doesnt find anything with airodump-ng... here are some things you might ask for.

Firstly can you mind the language please.

Secondly this will get confusing very quickly if we're working on 2 PC's with different setups at the same time .. I mean, I have no idea what has or hasn't been done on the laptop, no idea what distro/version, etc.

Also can we leave and airodump-ng out of it .. I can't help with that, and because (IIRC) it sometimes needs a modification to the wireless cards firmware, which *may* have a bearing on whether the card works or not as a regular Wifi adapter ?

I will try to help you with the drivers to get the card working as a normal Wifi card if you want, but need to know if you've been messing with the firmware ?

@BkS

It is kinda funny as an SSID, but not so much on a public forum that's here to help everyone, including kids and those that may be offended.

Post by: Mark Greaves (PCNetSpec) on March 02, 2012, 09:02:12 pm

Have you tried turning off wireless security in the router .. just to check if it connects .. you can turn it back on afterwards .. I just want to rule out encryption and/or a problem with the wireless key.

Can you also try setting the router to wireless G (54mbps) or mixed mode G/N .. and not N only .. just as a test.

Once we know it's not an issue with wireless security, or speed settings .. we can maybe try some other drivers.

I know this seems obvious, but have you also ruled out it just being a signal strength issue ?

Can you send the output from

Code: [Select]

ifconfig

and

Code: [Select]

iwconfig

and

Code: [Select]

iwlist scanninng

[EDIT]

Also, turn OFF the onboard wireless adapter .. so we're only working with the rt3572 based card.

Is the rt3572 set to get its IP from the routers DHCP server ? or have you given it a static IP ?

Something else I've noticed (from your previous iwconfig output) is that the adapter seems to be in "Auto" mode .. can you go into NetworkManager and set the mode to "infrastructure".

I checked all the settings and they are what you said they should be at. I removed all security and reset the SSID to default "TRENDnet TEW-691GR"

It connected for about 2 minutes then disconnected I was typing this message when it stopped.

Here are the outputs from the commands. I am working with the onboard wireless for now, and the receiver is not but 5' away from the router

OK, let's try an older pre-modified driver ..
(this is pre-modified, so no need to change the WPA lines in config.mk)

Just follow these instructions -

Open a terminal and run:

Code: [Select]

cd ~

then

Code: [Select]

wget http://dl.dropbox.com/u/11876059/2010_0709_RT3572_Linux_STA_v2.4.0.1.tar.bz2

then

Code: [Select]

tar -xjvf 2010_0709_RT3572_Linux_STA_v2.4.0.1.tar.bz2

then

Code: [Select]

cd 2010_0709_RT3572_Linux_STA_v2.4.0.1

then

Code: [Select]

make

then

Code: [Select]

sudo make install

then

Code: [Select]

sudo modprobe -r rt3572sta

then

Code: [Select]

sudo modprobe rt3572sta

Then check the version with:

Code: [Select]

modinfo rt3572sta | grep version

if it reads -
version: 2.4.0.0

REBOOT, and test your wireless.

Mark, You amaze me. Thank You so much! It is finally working, and believe it or not, It has a light on it.... i never saw the light on the adapter before. I saved the download for all my other machines.

The only problem now is that airodump-ng doesnt work, it doesnt display any networks... can you help me with that? Do you know anything about aircrack? Should I start a new thread for it?

Title: Re: Ralink RT2870 based USB Wireless N adapters (Ubuntu)
Post by: Mark Greaves (PCNetSpec) on March 03, 2012, 02:10:54 am

As far as I'm aware, I *think* you have to put the adapter into "monitor mode"

But I'm not an aircrack/dump-ng expert .. you'd probably be better off asking on their forum:
http://forum.aircrack-ng.org/index.php (http://forum.aircrack-ng.org/index.php)

Sorry.

[EDIT]

Bit of info (which could be wrong) .. this topic:
http://forum.aircrack-ng.org/index.php?topic=7108.0 (http://forum.aircrack-ng.org/index.php?topic=7108.0)
*seems* to suggest the rt3572sta driver isn't supported by aircrack-ng, but the rt2800usb driver IS supported.

The good news for you is that I'm *fairly* sure your cards ID strings (148f:3572) have been added to rt2800usb in kernel 3.2 .. so you can either wait for Ubuntu 12.04, Switch to Debian, or install the 3.2 kernel in 11.10

It's definitely supported by the rt2800usb thats included in the 3.2 kernel in Debian .. see here:
http://wiki.debian.org/rt2800usb (http://wiki.debian.org/rt2800usb)

Anyway .. Good luck.

Title: Re: Ralink RT2870 based USB Wireless N adapters (Ubuntu)
Post by: fatguy1121 on March 03, 2012, 05:27:18 am

Well, I kinda screwed myself because the whole reason I got this network adapter was so that I could use aircrack-ng. All of my Atheros wireless cards dont have native linux support and I figured that if I found one that did have native linux drivers that I could. Then I went off and bought this card..... So if I update the kernel to 3.2 will I need to reinstall the drivers and crap?

Title: Re: Ralink RT2870 based USB Wireless N adapters (Ubuntu)
Post by: Mark Greaves (PCNetSpec) on March 03, 2012, 11:43:03 am

Hopefully not .. you'd (hopefully) just need to use the rt2800usb driver (which is built into the 3.2 kernel) instead of the rt3572sta staging driver.

If you can wait till tomorrow, I'll test it and get back to you.

Meanwhile it would be a good idea for you to search the aircrack forums for any info on whether the rt3572sta drivers ARE supported .. and if not, how to make it work with the rt2800usb drivers (if we can get them to work)

At the end of the day I may be able to help get the rt2800usb drivers to work with your card .. but I won't be able to give you help with aircrack-ng .. the last thing I want is to get bombarded by requests for hep with aircrack-ng, so have to run off and learn all the ins and outs of it ;) .. that's what *their* forum is for :)

Have you considered asking if you can return the card for another make/model, then asking on the aircrack-ng forum for suggestions on which one to get ?

What makes you think this card has a Ralink chip ? .. your lsmod output seems to be suggesting it's a Realtek chip, my guess is an

product: RTL8188CE 802.11b/g/n WiFi Adapter
vendor: Realtek Semiconductor Co., Ltd.

Can you post the output from:

Code: [Select]

lspci -vnn

So we can get the Vendor:Product ID string, and work out what the card is.

Can you also post the output from

Code: [Select]

sudo lshw -C network

and

Code: [Select]

ifconfig

and

Code: [Select]

iwconfig

and

And preferably a description of what the problem actually is ..

Hi!

Wow, you seem to rock hard!

I just got a Tenda Adapter W311MI and it claims to have a 148F:5370, but I tried the original driver and it did not work, I also tried your 5372 driver and it loads but does not show any devices, I am about to try installing linux 3.3 on Centos 6.2 x86_64 instead.

Any suggestions? I would love a fail safe to be able to use this 5370 card on any linux based distro (at least ubuntu 11.10/12.04) if at all possible, just if it is not too much to ask, could you point me in the right direction?

Your devices vendor:product ID strings are contained in the Ralink
2011_0225_RT5370_RT5372_Linux_STA_V2.5.0.1_DPO.tar.bz2
driver.

Which can be downloaded from here:
http://eng.ralinktech.com.tw/en/Products/support_list.php?sn=5003# (http://eng.ralinktech.com.tw/en/Products/support_list.php?sn=5003#)

You'll have to fill in a name and email, but you can put whatever you like (it's not checked), and click the Accept button.

Name:a
email:[email protected]

will do

DON'T FORGET - be sure to make the edits to /os/linux/config.mk if you want/need WPA(2) support .. and that make && make install MUST be run as root.

and the you have to modprobe rt5370sta not rt2870sta

You *may* also need to blacklist the rt2870sta module if it's being loaded.

Take a look at;

Try adding;

This line:
make: *** /lib/modules/2.6.32-25-generic/build: No such file or directory. Stop.
suggests you don't have the kernel headers for your kernel installed

Run a full system update.

then REBOOT

then make sure you have build-essential and linux-headers-generic installed:

Code: [Select]

sudo apt-get install build-essential linux-headers-generic

any errors from that command, post them here .. if not, carry on below

then try building 2.4.0.1 again without making any edits

Don't know why make failed, but the procedure will be different for a VM.
What is the host CPU & OS? Do you have the guest extensions installed (if applicable - I'm only familar with Virtualbox myself)?

BE AWARE
For kernels >= 2.6.35 make sure you read the the EDIT.

If you want to know which kernel you are using, open a terminal and enter:
Code: [Select]
uname -r
(if it's greater than, or equal to 2.6.35, be sure to follow the instructions in the EDIT.

In Ubuntu 9.10 (Karmic), Ubuntu 10.04 (Lucid), and Ubuntu 10.10 (Maverick) there is an issue with USB Wireless N adapters based on the Ralink RT2870 chip.
The issue seems to be that 2 (conflicting?) driver modules are loaded... rt2870sta and rt2800usb... resulting in no wireless access.

The solution is to blacklist the rt2800usb module if it is loaded.

To see if they are both loaded, enter this in a terminal:
Code: [Select]
sudo lsmod | grep rt28
if they are both loaded, blacklist the rt2800usb module by opening the /etc/modprobe.d/blacklist.conf file (as root)
Code: [Select]
sudo gedit /etc/modprobe.d/blacklist.conf
and add the line:

blacklist rt2800usb

then save the file and reboot.

If after rebooting you can now 'see' the network, but it will not accept a WPA key (WEP seems fine)... you need to recompile the driver with WPA support... the driver can be found here:

2010_0709_RT2870_Linux_STA_v2.4.0.1.tar.bz2 ([url]http://http://eng.ralinktech.com.tw/license_us.php?n=2&p=0&t=U0wyRnpjMlYwY3k4eU1ERXdMekEzTHpBNUwyUnZkMjVzYjJGa05ETTVOalU0TXpVeU5pNWllakk5UFQweU1ERXdYekEzTURsZlVsUXlPRGN3WDB4cGJuVjRYMU5VUVY5Mk1pNDBMakF1TVM1MFlYST1D[/url]) (you can enter 'any' name and email)
or
Ralink Linux Driver Page ([url]http://http://eng.ralinktech.com.tw/en/Products/support.php?sn=501[/url])
(~~HINT~~ - ~~change the files extension to tar.gz before unpacking... for some reason it comes up as an invalid bz2 archive, but unpacks properly as a tar.gz~~)

Before compiling - you are going to need to install build-essential, and linux-headers-generic.
Code: [Select]
sudo apt-get update && sudo apt-get install build-essential linux-headers-generic
If you use WPA/WPA2 encryption, you will have to change the lines
HAS_WPA_SUPPLICANT=n
and
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=n

in:
/os/linux/config.mk
(inside the unpacked driver)

to
HAS_WPA_SUPPLICANT=y
and
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y

Once you have changed these to =y and saved the config.mk file...

[EDIT]
Newer kernels >= 2.6.35 will fail to compile (make) the driver because the driver makes use of the functions usb_buffer_alloc() and usb_buffer_free() which were renamed in kernel 2.6.35 .. so if during the next (make && make install) step it fails with this error:

Quote
make[2]: *** [/home/mark/Desktop/RT2870/os/linux/../../common/cmm_mac_usb.o] Error 1
make[1]: *** [_module_/home/mark/Desktop/RT2870/os/linux] Error 2
make[1]: Leaving directory `/usr/src/linux-headers-2.6.35-27-generic'
make: *** [LINUX] Error 2

or similar.

The fix is to cd to the driver source directory (eg. 2010_0709_RT2870_Linux_STA_v2.4.0.1), and run the following 3 commands which will clean the build directory and replace the old calls with the new ones:

Code: [Select]
make clean
find . -name \*.[ch] -exec grep usb_buffer_alloc "{}" ";" -exec sed -i 's/usb_buffer_alloc/usb_alloc_coherent/g' "{}" ";"
find . -name \*.[ch] -exec grep usb_buffer_free "{}" ";" -exec sed -i 's/usb_buffer_free/usb_free_coherent/g' "{}" ";"
(hitting enter after each line)

Or, I've uploaded a pre-modified version of the driver that WILL compile on kernels >= 2.6.35 here:
2010_0709_RT2870_Linux_STA_v2.4.0.1.tar.bz2 ([url]http://http://bit.ly/eZHx0J[/url])

Then carry on with the "sudo su" and "make && make install", as per the instructions below.
[END EDIT]

To compile and install, open a terminal and enter:
Code: [Select]
sudo su
make && make install
It is important here not to use "sudo" alone, but "sudo su" because with sudo for some reason the installation script fails to create the necessary files and folders.

Now, while still root modprobe the driver module:
Code: [Select]
modprobe rt2870sta
Give it a minute to create the ra0 device node, and network manager should now be able to display all visible wireless networks in your area, meanwhile you can stop being root.
Code: [Select]
exit
Make sure that ra0 is up and running as it's supposed to:
Code: [Select]
iwconfig
and check for a section similar to:
Quote
ra0 RT2870 Wireless ESSID:"" Nickname:"RT2870STA"
Mode:Managed Frequency=2.412 GHz Access Point:
Bit Rate=54 Mb/s
RTS thr:off Fragment thr:off
Link Quality=100/100 Signal level:-29 dBm Noise level:-71 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

To make sure the module is loaded after a reboot, add it to the /etc/modules file:
Code: [Select]
sudo sh -c 'echo rt2870sta >> /etc/modules'
Your wireless card should now be working (it may require a reboot first)... Use network manager to set your WEP/WPA(2) key, and connect to your network.

I have kernel 4.10.0-28-generic.

The results of doing lsusb gives me a bunch of listings. I cant copy it all as its from a computer that has no internet but amongst them there is a MediaTek Inc. item which is the wireless USB device.

(if it's a USB wireless card)

or

Your wireless adapter uses the MT7610U chipset.

Okay you're going to NEED an internet connection to do this, so either connect to your router with an ethernet cable, or borrow a wireless adapter that works OOTB.

At this point I'm assuming you're running Ubuntu or an Ubuntu based distro....

Once connected to the internet, open a terminal and run these commands in sequence:-

Code: [Select]

sudo apt-get update

then

Code: [Select]

sudo apt-get dist-upgrade

Once that has finished, REBOOT <-- IMPORTANT

Once rebooted, connect to the internet again, open a terminal and run these commands in sequence:

Code: [Select]

sudo apt-get install build-essential linux-headers-$(uname -r) git dkms

then

Code: [Select]

mkdir ~/mt7610u-driver

Okay internet is connected through cable

I have immediately bumped into an issue on your very first step. I get the following:
Reading package lists... Done
E: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable)
E: Unable to lock directory /var/lib/apt/lists/

I googled this and people gave plenty of warnings about possible risks of typing in wrong commands to fix this.

This is a fresh out the box Ubuntu with no prior tinkering. And it was booted fresh. No multiple processes running.

EDIT: After trying numerous times, the first step finally worked randomly. So much for Linux "robustness". Will update as I go by

Right after I hit enter of the last step, it seems to execute the command then a GUI prompt comes up: System program problem detected. Do you want to report the problem now? I reported it and then it says sorry, Ubunu 16.04 has experienced an internal error. If you notice further problems, try restarting the computerl. I clicked send error report to help fix this problem. Im going to restart and see if the device is working.

Your wireless adapter uses the MT7610U chipset.

Okay you're going to NEED an internet connection to do this, so either connect to your router with an ethernet cable, or borrow a wireless adapter that works OOTB.

At this point I'm assuming you're running Ubuntu or an Ubuntu based distro....

Okay now I dont mean to be a pain. But.... the device is not connecting anymore. This Ubuntu robustness over Windows is proving to be a myth and is pissing me off to be honest.

Any idea how to make it work again?

I used the device on my windows laptop and it worked. On Ubuntu PC the light doesn't come on.

Furthermore doing a lsusb shows it is indeed plugged in.

Router is also A OK

Any ideas?

Post by: Mark Greaves (PCNetSpec) on September 12, 2017, 01:14:20 pm

They force the dkms version of the drivers to recompile for the current kernel .. I'm guessing you received a kernel update and the driver didn't automatically get recompiled (as it should).

Write those 2 commands down in case it happens again when you get your next kernel update .. theoretically it should be automatic, that's the whole point in dkms, but maybe the dkms function of the drivers was incorrectly written (not really a Linux problem, more that the manufacturers don't supply Linux drivers so it was left to the community to step in).

I found and installed MediaTek's DPO_RT5572_LinuxSTA_2.6.1.3_20121022 version of the drivers which should support this device, but get different errors with it.

I was hoping to grab and use the 2010 drivers you have referenced in the feed, but the drop box location is no longer available and I can't locate the file elsewhere.

Can you freshen up the link so I can grab and try that driver? Or maybe you have some insight for this device that might get me further?

I appreciate the help you have provided for the last 5+ years on this message feed! Thanks!

Hi everybody!
I have an issue with my USB dongle. It's the rt2870 chip from NoNameChinaCorporation )
I've installed Debian 6 Squeeze:

Code: [Select]

Linux debian 2.6.32-5-686

and followed this instruction: https://wiki.samygo.tv/index.php?title=Using_NoN-Samsung_USB_WiFi_dongles_with_TV

but I can't compile before I add

Then I have a new error when I try to modprobe:

Hi Ale-x, and welcome to the forum :)

Here's the premodified version from my dropbox (mentioned in the link you provided), but I'm unsure it'll compile against the 2.6.32 kernel, it was modified for the 2.6.35 kernel

https://www.dropbox.com/s/kn385v8muztotdv/2010_0709_RT2870_Linux_STA_v2.4.0.1.tar.bz2?dl=0 (https://www.dropbox.com/s/kn385v8muztotdv/2010_0709_RT2870_Linux_STA_v2.4.0.1.tar.bz2?dl=0)

If that won't compile (and it probably won't), let me know and we'll see if we can find the unmodified version that may compile against 2.6.32 .. though it might just be easier to update to the 2.6.35 kernel.

Hi Mark, this always used to work for me (your remove command should actually write ...sta/1.0 and not ...sta/1.02).

Now it has stopped working.

When I try the install (the second command) I get a bad exit status of 2. it says the binary package is not found.

Also when I reboot the same prompt comes up as soon as loading up.

Hey guys

Sorry for bringing back the topic but I've searched an answer for 2 days now but still can't figure it out.

I pretty much tried everything in this thread but nothing has worked yet

I just installed Ubuntu 18.04.LTS on one of my laptop. I'm trying to install the driver for my ALFA AWUS036NH but it's a nightmare. The laptop think it's the rt2800 driver, so when I turn off the built-in wifi, the wireless card shut down. I've blacklist the rt2800usb but I can't install the rt2870 driver at all.

It does show up when I type

Let me know what you need from my Terminal!
