Title: Slow download
Post by: Emegra on July 11, 2013, 07:04:19 am
Hi Guys

I recently installed Peppermint 4 on an oldish PC for the missus as hers packed up, anyway this is her first time using Linux and she's very happy with it so far, the internet is working fine and network seems stable but the download speed is painfully slow, downloading from synaptic shows download speeds of less than a kb/s, even downloading a theme into Chromium took about 5 mins (no exageration) something that would normally be done in seconds.

this is an oldish PC we've set up untill we can get her a new one but it was an opportunity to introduce her to Linux as I couldn't be bothered to install Windows on it, it has a 1.2 ghz amd single core processor and 2.2 gb ram, other PC's on the network don't have this problem so it seems the problem is with this PC.

Any help or advice would be much appreciated


Many thanks



Graeme

How is it networked .. wireless ?

Which adapter/driver:
Code: [Select]
sudo lshw -C network
?

is it a USB adapter ?

If wireless, also post the output from:
Code: [Select]
iwconfig
and
Code: [Select]
iwlist scanning

Yes wireless PCI card

For some odd reason it wont list hardware with sudo when I put in the command then password it comes up with PCI (sysfs) then shifts to SCSI and sits there endlessly I tried a few times and left it for a considerable time, as follow

Code: [Select]
[email protected] ~ $ sudo lshw -C network
[sudo] password for pat:
SCSI                     

Without sudo

Have you compared the speed of moving a fixed size file between your pc and nas?
This would test the local network speed. Compare this with other machines on your network.

If it is comparable then your wireless card is working OK except the internet access is questionable.
Title: Re: Slow download

Hi SeZo

Thanks for your input, I'm still at work but will try your suggestion later when I get home




Many thanks

Title: Re: Slow download
Post by: Emegra on July 11, 2013, 09:25:21 pm
Ok I carried out SeZo's suggestion involving 3 PC's Linux 2 (chloe), Linux3 (graeme), Linux4 (pat), Linux 4 is the PC in question

I attempted to copy a music album from the NAS to each PC with a file size of 535mb

Linux2 failed to copy as the network connection constantly drops out, which is an issue I was gonna deal with later

Linux3 copied 8% of the file in 3 minutes with 22 mins reported time remaining

Linux4 copied 3% of the file in 3 minutes with 1hr: 15mins reported time remaining



I also done a internet speed test comparison between Linux3 & Linux4

Linux3

Download:   303 kb/s
Upload:       340.5 kb/s

Linux4

Download: 140.5 kb/s
Upload:     296.6 kb/s

of the 3 machines Linux3 has the highest spec but I'm not sure if that's the reason for the faster download speed or if there is a network issue affecting the other 2 PC's

Many thanks

Graeme

I do not have a solution for you, but number of things seems odd to me:

The folder download from your NAS could be hampered by slow writing disks. It would be better to copy something to the NAS instead.

The internet speed seems odd, Usually the download is faster than upload or is this a Virgin feature?
I get with WifI connection (in the garden):
Bit Rate=54 Mb/s   Tx-Power=20 dBm
http://www.broadbandspeedchecker.co.uk/ (http://www.broadbandspeedchecker.co.uk/)

      Download speed   2246 Kbps
      Upload speed    350 Kbps

On the data you provided previously it shows
Tx excessive retries:2243  Invalid misc:706   Missed beacon:0

contrast that with mine (AA1)
Tx excessive retries:0  Invalid misc:4   Missed beacon:0

According to Iwconfig man page:
Tx excessive retries
    Number of packets that the hardware failed to deliver. Most MAC protocols will retry the packet a number of times before giving up.


Could you please post the contents of /etc/network/interfaces file

Post by: Mark Greaves (PCNetSpec) on July 12, 2013, 01:07:00 am
Those download speeds are atrocious,

As all the PC's seem to have a rubbish download speed, I think the first thing you need to do is take wireless out of the picture and see if it's a problem with the router/filters (if adsl)/line/ISP.

Can you connect a PC to your router with an ethernet cable .. then (preferably with all other kit including NAS switched off) go to SeZo's speedcheck link:
http://www.broadbandspeedchecker.co.uk/ (http://www.broadbandspeedchecker.co.uk/)

and get some figure.

Mine-

Download = 5.73 Mb/s
Upload = 0.832 Mb/s
 
At least this will rule in/out wireless.

Hi Mark
Thanks for you input

I have a laptop I can connect to the router via ethernet and I'll do that as soon as have time

The download & upload figures I posted were from this web app http://speedtest.appsmaster.co/ (http://speedtest.appsmaster.co/) which seem vastly different from the link SeZo posted here's a comparison



Linux2

speedtest. appmaster: Download= 146.0 k/s    Upload=180.2 k/s

broadband speedchecker: Download=0.957 mb/s   Upload=2.72 mb/s


Linux3

speedtest. appmaster: Download= 523.6 k/s    Upload=340 k/s

broadband speedchecker: Download=6.75 mb/s   Upload=2.90 mb/s


Linux4

speedtest. appmaster: Download= 265.6 k/s    Upload=323.0 k/s

broadband speedchecker: Download=1.21 mb/s   Upload=2.06 mb/s

I don't understand why the results from the 2 apps are so vastly different ( unless I'm misinterperating the results) but 2 things are consistent,  one is that Linux3 is much faster than the other 2 PC's and that in all cases the upload speed is faster than the download speed which from what I'm led to believe is unusual

In addition to the slow download speed of Linux 2 & 4, Linux2 (Chloes PC) constantly drops internet connection and as she uses a few web app such as uptoten & istorybook etc, renders her PC pretty much unusable



Confused

Post by: Mark Greaves (PCNetSpec) on July 12, 2013, 12:02:46 pm
Just goes to show that non of the speedtest sites figures should be trusted for anything more than comparison.

OK, I suspect the issue on Linux 2 and 4 are driver related (or possibly house position), they appear to be having issues receiving/understanding the signal from the router .. but the router is understanding them just fine.

So unless Linux 2 and 4 are further away from the router than Linux 3.....

So let's look into drivers.

Let's do this one at a time so things don't get confused .. above you posted the output from "lshw", so let's stick with this machine first.

That box is using the open source rt2800pci drivers, so let's try the one from staging instead .. from that machine can you post the output from:
Code: [Select]
lspci -vnn | grep -i net

[EDIT]

Be sure to do this on the one you posted the lshw output from above

Actually there's something you  can try on that machine before we look into the staging drivers .. disable hardware encryption in the rt2800pci driver.

run:
Code: [Select]
sudo modprobe -r rt2800pci
then
Code: [Select]
sudo modprobe rt2800pci nohwcrypt=1
and see if the speeds improve .. also check the "TX excessive retries" goes down when you run:
Code: [Select]
iwconfig
after having used it for a while.

ok I ran it for a while and tried the speed test from the same sites as before and it's now way slower so much so that I had to stop speedtest.appmaster as it didn't look like it would finish the test, with broadband speedchecker the download speed is down to .486.0 mb/s from 265.6 mb/s, I also tried running a you tube video because i was having trouble with stuttering but now it just freezes completely

I ran with the usb adaptor for a while and to begin with it seemed faster then it began to slow down then started dropping connection, so I've reverted back to the pci and it's pretty much like it was at the beginning, anyway I've had the day from hell and I'm off to bed to put this day to rest, I'll follow any instructions you may care to give in the morning

There's something weird going on here.

Was it like this with your old router .. or has this only started since you got the superhub ?

Have you tried restarting the superhub ?

Was it like this with your old router .. or has this only started since you got the superhub ?

Difficult question to answer because the problem began when the wifes Windows PC packed up and I set up an account on Chloes PC (Linux2) for her as a temporary measure until we could get her another PC,

Linux2 and the Windows PC worked through a KVM box so they shared the same keyboard mouse & monitor, Linux2 always had a solid network connection and was relatively fast so she was happy with that meantime.

 then after a week or so for some unknown reason the network on Linux2 suddenly became painfully slow to the point where it became unusable, so I had an old PC in the attic that I was going to build another NAS with when I had the time,  so I decided to set up that machine for her and installed Peppermint 4 (Linux4),

To solve the sudden slow connection problem with Linux2 I wiped the drive and installed Peppermint 4, although that  sorted the slow connection speed it created the new problem of the connection constantly dropping out, I didn't report that problem on here because at that time I knew the Virgin Superhub would be arriving soon and I wanted to see if that would sort the problem first, which as it turned out didn't.

The Superhub arrived a few days later and although I only noticed the slow download speed of Linux4 after that, it doesn't mean it wasn't there before it because the problem isn't instantly noticeable, general browsing and communication with the NAS was OK although perhaps a bit sluggish.

So answering your question is difficult because so many different events occurred around the same time making it difficult to nail the problem down to any one particular thing, but I'd be reluctant to blame the problem on the Superhub because throughout all this the connection on my PC (Linux3) has been solid and lightening fast, before and after the new Superhub was installed

I'm sorry for the long winded post, I've probably given you a lot of pointless information you didn't really need to know, but I just wanted to give you as clear and complete a picture of the situation as I could



Many thanks

Well the thing I find odd is that even using another wireless adapter, it starts off quick, then progressively slows down.

So I'm wondering if the superhub is just rubbish at handling multiple wireless connections.

I'm wondering if we should try using your old router as the wireless access point, and connecting that to the superhub by an ethernet cable .. thereby only giving the superhub a single (non wireless) connection to worry about.

You game for experimenting ?

Are you in a built up area .. I mean are there a lot of other overlapping wireless access points all using the same channel ?

What's the output from:
Code: [Select]
iwlist scanning

If you have the time

I might have another option which is a while back I bought a Virgin Wireless modem/router (not a superhub) at a boot sale, I've never tried it but it's there as an option if you want, but I'll go with whatever you think best, prior to getting the Superhub I was using an old Motorola Surfboard modem + my own wireless router which actually worked fine but I can't go back to that now because they took away the Surfboard Modem

I live in a city but not in a particularly built up area, about 5 or 6 networks show up under "available networks" which are just my immediate neighbours. but I don't know what channel they're using

I'm still at work at the moment but I'll send the output from iwlist when I get home

Let's find out then ;)

this *may* just turn out to be interference from the other networks, or maybe not, but worth a shot as it's an easy solution if it works and an easy test.

Nearly all ISP's standard kit comes pre-configured to use channel 6 or 11 .. so this can happen.
(personally I always scan the available networks, then pick a channel as far away from what everyone else is using as possible)

If you got loads of networks in your area you could just filter the output:

sudo iwlist scan | grep Channel

Most are either on Channel 7 or 12 in my area.
Title: Re: Slow download
Post by: Mark Greaves (PCNetSpec) on July 13, 2013, 03:44:39 pm
I'd rather Emegra doesn't filter the output .. I also wanted to see the signal strength of all the overlapping networks and the encryption type.

But DO use "sudo" as suggested by SeZo (and fixed in my command above)

You can surround the output with "spoiler" tags if you like though :)

3 things spring to mind

a) is there an option in your superhub to switch from "tkip" to "aes" encryption .. or even to drop encryption altogether and switch from WPA2 to WEP ? (even just to test)

and

b) there appear to be 2 networks in range .. remember when you had the issue changing the routers IP and we had to juggle IP addresses because of hidden networks .. I'm wondering if Virgin are doing similar to the BThomehubs, where they actually have 2 (or more) networks, your private one and a public "hotspot" one .. is there an option to disable this in the superhub.

the dual networks on BThomehubs made a lot of machines drop connections .. now whilst I'm not saying this is the problem here .. it's worth investigating.

c) in some cases the signal strength on the "emegra" network appears to be weaker than the "virginmedia5139198" network .. are you miles away from the router (or have thick brick walls in between) ?

What i'm saying is, if you move the PC that gets a good connection to the same palce as the ones that don't, does it suffer too ?

I'm wondering if Virgin are doing similar to the BThomehubs, where they actually have 2 (or more) networks, your private one and a public "hotspot" one .. is there an option to disable this in the superhub.

Yes i remenber but you also asked me later on if I had another network adaptor to try.and as it turned out I had a spare USB adaptor which I plugged in which might explain 2 networks

Code: [Select]
c) in some cases the signal strength on the "emegra" network appears to be weaker than the "virginmedia513 9198" network .. are you miles away from the router (or have thick brick walls in between) ?

The router and NAS are in my attic , however the PC's are located on the upper level of the house, making them no more than 10 feet from the router as the crow flies

NO .. that would explain the 2 wireless adapters (wlan0 and wlan1) butt there are ALSO 2 distinct wireless access points.

I suppose one could be a neighbours .. but it's giving a stronger signal then the "emegra" network, and is called "virginmedia5139198"

Have you still got the old router plugged in somewhere too ?

What's the name of the access point you're currently connected to .. emegra ?

[EDIT]

Is there a setting to turn off the "guest network" ?

if you go to advanced settings>wireless>wireless and set the wireless mode to 54Mbps .. is WEP ungreyed now ?

BTW, I'm beginning to think these superhubs suck  :o

Hi guys

Sorry I've taken a while to get back to you, I've been working in the garden all day and I was knackered

anyway back to business

"Network Emegra"  (the original SSID for my Superhub was virginmedia 8286556)

Quote

There are 2 guest networks (SSID2 & SSID3) both are disabled

WEP becomes available when I switch to 54mbps

I've left the wireless mode set to 54mbps is that ok or should I put it back to where it was ?

it's safe to leave it at 54G if you want .. before changing to WEP, has just changing to 54G improved anything ?

I'm still a little baffled by this second "virginmediaXXXXXXX" network .. can you turn off your superhub, then post the output from:
Code: [Select]
sudo iwlist scanning
then you can turn it back on.

I just want to see if that's a neighbours network .. or emanating from your superhub

Well the only thing showing up there is a BThomehub

So I guess that virginmediaxxxxxxx network MUST be a second network on your superhub.

OK .. is there a setting in your superhub called something like "modem Mode" ?

The links here may help:

DON'T SELECT IT YET .. just see if it's available.

We can use your old router for ethernet and wireless.
(actually we can probably do this anyway)

You'll obviously need a spare ethernet cable too .. have you got one ?

Yes it's there

Quote

Yes I still have my old router and ethernet cable
it seems from your links that I'm not the only one having problems with the Superhub but it's a bad business if we have to do this to get a decent internet connection as the only advantage of the Superhub compared to what I had (seperate modem/router) is it takes away an extra power adaptor and ethernet cable, but if nothing else it will be interesting to see if it works.

Just to update last night I changed the wireless mode in the router wireless settings to    "Up to 300Mbps (best for wireless performance)"  and I ran speedchecks with broadbandspeedchecker.co.uk early this morning and there is a huge speed increase with Linux 2 & 3

Linux2 Download= 6.36mbps                  previously 0.957mbps
              Upload=   2.57mbps                  previously 2.72

Linux3 Download= 22.21mbps                previously 6.75
              Upload=     3.02mbps                previously 2.90

I couldn't run the speedtest on Linux4 as it's now running  too slow to even open the page let alone run the test

these figures are much better than I was getting before (although there's still a vast difference between the two), I'm not 100% sure if the speed increase is due to the changes I made to the wireless mode or because it was early morning I ran the test when there would have been little wireless traffic in my immediate area

further to the problems with Linux4 we now have a red circle with a white strip in the taskbar, clicking on it shows the following  serious error

Okey dokey.

I'm thinking it would be worth testing the original router/modem to see if the dropouts stop and the speedtest results improve.

At least that should tell us if it's the superhub at fault .. Personally I think it is, a LOT of other people say the wireless is rubbish on them (amongst other issues) .. and there must be a reason they put "Modem Mode" in there ;)

[EDIT]

I take it the original setup was a separate cable modem and router ? (2 boxes) ?

Have you got make(s)/model(s) for those ?

Yes it was a Motorola Surfboard Cable Modem and a Belkin Wireless Router I can give you the exact model of the router when I get home but I dont have the modem anymore as the engineer took it away when he installed the Superhub, I also have a Virgin Media Modem/Router (not a Superhub) I bought at a boot sale but I've never tried it, I think it's a Netgear.

Title: Re: Slow download
Post by: Mark Greaves (PCNetSpec) on July 16, 2013, 04:03:24 pm
Well I suppose we could put the Superhub into "Modem Mode" and use that as the modem .. but we'd better make sure we know how to reset it if necessary.

Yeh, models of both Belkin and Netgear kit would be handy .. you never know, someone may have already written a "how to" .. or at the least we can get their respective manuals.

I'm sure I saw a reset button on the Superhub but once again I'll confirm that when I get home

I suppose we'd have nothing to lose if we tried the Netgear modem/router if we could get in working

But when I get home I'll post all the relevant information regarding all the hardware and i'll go by whatever you think is best

Ok the wireless router i was using with the Motorola Surfboard is a Belkin F5D7234-4 v3 wireless G

The Modem/Router is a Netgear VMDG280, the default SSID & Passphrase are on the side so it should be a simple matter to set it up (where have I heard that before)

The Superhub has a small reset button it so i assume if things went horribly wrong we could get ourselves back to square 1 again

Let me know how you wish to proceed

Not ignoring this posting .. just been a bit busy and want to do a bit of homework on the Superhub first.

The problem is I want to be 100% sure how to get back to where you are now before saying "switch to modem mode".

Is there an option to export the current settings (to a file) in the superhub (and to import the settings from the file again) ?

Does the Superhub require you to enter account details .. and if so, do you know what they are ?
(don't post them here .. I just want to know if you know them)

Title: Re: Slow download
Post by: Emegra on July 16, 2013, 11:43:59 pm
Just an update, I've been messing about with this all evening, first of all I tried the Netgear Modem/Router but in spite of several attempts of resetting to factory settings it wouldn't accept the passphrase on the side of the box so I gave up on that, all the PC's on the network give very good connection speeds apart from Linux4 which I find odd if the problem is coming form the hub, so eventually I tried running several live discs I had lying around, Zorin connected to the internet no problem and ran well , Bodhi also connected no problem and ran well, but in spite of several attempts I could not get a Peppermint 4 live session to connect to my network at all, so could I have a bad installation disc or could there be something about my hardware that P4 doesn't like, this PC I'm on now (Linux3) is running Peppermint 4 and has no issues at all and getting amazing download speeds

Anyway it's all very confusing it's late and my brain hurts

Goodnight

OK because of your last but one posting, I'm now thinking it's NOT the superhub

On the problem machine (Linux3) can you boot the LiveCD's of Zorin and Bodhi .. and post the output from:
Code: [Select]
uname -a
and
Code: [Select]
sudo lshw -C network

Can you also try a Peppermint 3 LiveCD

If it's OK in Bodhi and Pepeprmint 3 (both based on 12.04 so probably using the 3.2 kernel), I can only assume it's something to do with the rt2800pci wireless driver in the 3.8 kernel .. then we can try some others, 3.9 for instance.

[EDIT]

or possible the firmware .. Whilst you try that and post the output, I'll look into the firmware:

Hi Mark

Below are the outputs you asked for, however I think I may have stumbled upon the problem or at least a part of the problem,

There was 2 network adaptors installed on the machine and internal PCI and a USB,

Before I started booting the live discs to get the outputs you asked for I removed the USB so as not to cause any confusion, Bodhi was first and when it booted into the desktop it showed no available networks, but when I plugged in the USB adaptor it then showed 2 (the USB and the PCI) if I unplugged the USB again both networks disappeared, the same thing happened with Zorin but seemed to sort itself out when i booted into Peppermint 3, so now all live discs will see the network with only the PCI card installed, and connect to the network and the internet except Peppermint 4 live which will connect to the network but not the internet

The installed Peppermint 4 is back to where it was when first installed adequate but not great and broadbandspeedchecker is still showing poor download speed compared to the other machines on the network, unfortunately i cant run broadbandspeedchecker in any live session as it needs a flash plugin to work

You don't (or shouldn't) see 2 NETWORKS because you have 2 adapters fitted .. you should still only see the same networks.

but obviously you'll see 2 adapters.

Anyway .. do all 3 of those PM3/Bodhi/Zorin give acceptable wireless speeds ?

Why can't you run a speedtest in a live session .. no flashplayer ?

Try one of the other (non-flash) speedtesters .. such as:
http://testmy.net/auto (http://testmy.net/auto)
or
http://speedof.me/ (http://speedof.me/)



Or do you just want to go ahead and try the 3.9 kernel, and see if it makes a difference or not ?

I would really need your advice on that Mark what I know about kernels borders on the dangerous, I'm happy to run the non flash speed tests first on each live session if you think would it would help you make a more informed decision

It's probably already in here, but to save me trawling back through a long topic .. is PM4 on Linux4 32bit or 64bit ?

If unsure, send the output from
Code: [Select]
uname -a
and I'll type up instructions for installing the 3.9 kernel.

Speetest results can't hurt .. but I figure, we can just try 3.9 anyway.

cd ~/kernel-3.9
then
Code: [Select]
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9-raring/linux-headers-3.9.0-030900-generic_3.9.0-030900.201304291257_i386.deb

then
Code: [Select]
sudo dpkg -i *.deb
once that's finished and leaves you back at an $ prompt .. REBOOT.

Once rebooted, check you're using the 3.9 kernel with:
Code: [Select]

If so, check how wireless works now.



And remember, if anything goes wrong you can still select an earlier kernel from the GRUB menu.

ok I followed your instructions but the first download seemed to stall at 98% and sat there for over 20 minutes, so I gave up and created the directory on my PC downloaded the files then copied them over to the home directory via a USB drive of the offending PC then installed, then the reboot stalled for about another 10 to 15 minutes do I powered off and on again, once rebooted I checked I was running kernel 3.9 which I was, I was then offered updates mainly to do with open jdk and it's been installing them now for the past half an hour and not quite half way through, so it doesn't look good at the moment but I'll leave it as long as it needs and report back

Nope .. that doesn't sound promising :(

I'm beginning to think this may be better off with PM3 ???

I suppose we could try the firmware package from PM3/Precise .. maybe they screwed up the firmware somewhere along the line.
But I think it's more likely this is something else altogether .. such as screwe interrupts, etc. with later kernels

We could spend forever tracking it down .. or just swap to PM3, and if you want, make PM3 act/look like PM4 ?

could we simply have a faulty network card ??

What speeds do you get with the USB adaptor?
Title: Re: Slow download
Post by: Mark Greaves (PCNetSpec) on July 17, 2013, 09:42:38 pm
It must be a kernel regression if wireless works on all distros with the 3.2 kernel series .. rt2800pci is part of the kernel.

The only other thing is possibly they've updates the firmware for that card, and screwed it up.



What's the speed like with the USB card in PM3 ?

Try physically pulling the PCI card.

Yes that's what I'm saying but it gets even stranger than that

I pulled the PCI card and now I can't get any available networks with just a USB adaptor in either PM3 Live or PM4 Installed and that's trying it with 2 different USB adaptors

before I give you these outputs It seems I have more than one issue here because the PC wont recognise any USB device plugged into the main USB ports at the rear of the machine, the USB adaptors are recognised when I plug them into a USB hub but wont connect (probably lack of power)

So untill I can get a stable USB connection from this machine  I'm wasting your time

I can only appologise but these ports were working earlier
Title: Re: Slow download

Title: Re: Slow download
Post by: Mark Greaves (PCNetSpec) on July 17, 2013, 10:38:15 pm
Here's a thought .. can you BORROW the known good PCI adapter from another PC, and see if the USB card will work in that one ?

Have you simply tried plugging the PCI card into a different slot ?
(some PCI slots share interrupts badly)

I never tried that, but I can do that

What appears to happening is that one of the USB adaptors (Sumvision) seems to be taking out the main USB ports when plugged in so I'm now loading up PM3 Live with the other USB adaptor (Belkin) to see how it fairs

I got the Belkin connected in PM4 but it was very slow if it's slow in PM3, I'll try the PCI in another slot and report back

Sorry for all the confusion

PCI is NOT hot plugable .. attempting to do so could SERIOUSLY damage the card and the motherboard

It's not close to any magnetic field but it is right in front of a metal radiator which I suppose could be bouncing the signal

One last thing I'd like you to do tonight .. run:
Code: [Select]
dmesg > ~/dmesg.txt

you'll now find a file called dmesg.txt in your home folder .. can you attach that to your next posting, and I'll go through it tomorrow and see if I can spot anything

And yeh .. at some point it would be nice to know if switching to WEP (or disabling security altogether) helps

But remember, if you switch to WEP, you'll have to change the key in ALL PC's .. and preferably have a PC that you can connefct to the router by ethernet in cse you can't get any of them to connect with WEP .. though that's unlikely

Sorry Emegra, but I'm going to have to call it a night .. I need to install PM4 64bit on another PC so I can test some updates before releasing them.

Can we pick this up tomorrow ?

I'll go through that output tomorrow.

No problem whenever you're ready I've had enough anyway

sorry I took up so much of your time  :-[

Not a problem .. I wouldn't be here if I didn't want to be .. catch you tomorrow then :)

[EDIT]

This is for my own reference -

try Wicd .. and enable its log for clues.

try disabling IPv6

in light of the DNS issue .. try a static IP

try WEP or no security temporarily

try a KNOWN GOOD adapter from another PC .. there's a chance BOTH adapters are screwy.
Title: Re: Slow download
Post by: Mark Greaves (PCNetSpec) on July 18, 2013, 06:04:17 pm
Because dmesg suggests the adapted is having problems authenticating (so possibly BOTH of them are rubbish) .. I'd like to try -

a) a known working adapter from one of the other systems (if possible)

b) giving wicd a shot instead of networkmanager

c) switching to WEP

Which would you like to try first ?

Well from my way of thinking probably changing to a known good network card would give us good info because I could swap with the PC that works best is that ok ?
Title: Re: Slow download
Post by: Mark Greaves (PCNetSpec) on July 18, 2013, 07:21:26 pm
That's fine .. and makes a lot of sense .. it will rule in/out the adapter :)
Title: Re: Slow download
Post by: Emegra on July 18, 2013, 08:12:06 pm
OK I swapped the network cards between Linux3 (Which had a good connection) and Linux4 (Which has the bad connection) and there seems to be no difference to Linux3 it still returns a good connection speed (18.17mbps Download & 2.99mbps Upload) only the connection is weaker down to 49% from around 68%

at the moment Linux4 has connected to the network but wont connect to the Internet, it's showing connected at 43% but it wont open any webpages, I've tried rebooting but no luck

First of all .. in networkmanager, set

IPv6 "Method" = "Ignore"

Now send the output from:

Title: Re: Slow download

No I get exactly the same results

if it means anything I installed another OS on another drive on that PC and wont connect to the Internet either

This could be a long shot, but worth to try. Switch off all other equipment connecting to your Super Hub Wirelessly.
Try it with just the problem PC. See if you get any better results.

There's only 1 other device connected wirelessly which is this PC (Linux3) everything else is connected by ethernet ie 3 xboxes and a NAS box running freenas

But I'll give it a shot :)
Title: Re: Slow download
Post by: Mark Greaves (PCNetSpec) on July 18, 2013, 10:34:51 pm
I'm also beginning to think this is another hardware issue,, and not wireless at all

Possibly screwy interrupts ?

Another long shot .. Is there a BIOS option to reset the "DMI pool data" or similar

And is the BIOS set to "Plug and Play OS" ?
Title: Re: Slow download

I've been through all the bios menus and I see nothing about plug/play or DMI

sudo modprobe ath9k nohwcrypt=1
any improvement ?

Hi again guys

I connected up an ethernet cable and I'm definately getting far better download speeds

Download: 3.94 mbps
Upload:     1.37 mbps

You tube videos play much better as well and it's stable so although it's nowhere near as good as Linux3 (which hit 38 mbps download speed this morning) it would be acceptable if only I could get this wirelessly
Title: Re: Slow download

Yeah I know but it may be as good as I can hope for with this old machine, I don't really want to go down the home plug route because this PC was only set up until we can get a new one or newer one and it was also an opportunity to introduce the missus to Linux.

keeping it ethernet isn't really an option or at least not an easy one to implement due to router location etc

So unless I can get a half decent stable wireless connection the PC is really no use but having said that no great loss

Nothing ventured nothing gained :)

No I haven't but I can try I did attempt to install PM3 on another Hard drive but the installer kept crashing so I Installed Zorin 6 ( I can hear you growling from here :) ) would that work or would it be better with a live CD ?
Title: Re: Slow download

I have no idea on the interrupts, so I would leave that for Mark.
You could try Zorin for comparison.

What is preventing you connecting it up via Ethernet permanently.?
Is it lack of network ports on your rooter? Distance or cables being unsightly?
You told us that your NAS is in the attic and wired up, where are the xboxes in relation to this PC?

Well the router and NAS is in the attic and the 3 xboxes are in various rooms in the house , the PC's are in an upstairs room directly below the the router and NAS

The NAS is connected by a short ethernet cable and the xboxes are also connected by ethernet cables that I've spent a lot of time neatly running through trunking etc, so apart from all 4 ports on the router being occupied I dont want to have to run another cable for what is essentially a temporary PC, it is doable because I have a spare ethernet hub I can utilize to give me extra ports but it's a lot of work and I'm essentially lazy :)

Hub

A common connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple interfaces. When a packet arrives at one interface, it is copied to ALL other interfaces so that all segments of the LAN can see all packets.
(the downside is PC's/devices get packets that aren't intended for it, so have to discard them)


Switch

In networks, a device that filters and forwards packets between LAN segments. Switches operate at the data link layer (layer 2) and sometimes the network layer (layer 3) of the OSI Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs.
(Switches only forward packets on the interface they are intended for)

 
Router

A device that forwards data packets along networks. A router is connected to at least two networks, commonly two LANs or WANs or a LAN and its ISP.s network. Routers are located at gateways, the places where two or more networks connect. Routers use headers and forwarding tables to determine the best path for forwarding the packets, and they use protocols such as ICMP to communicate with each other and configure the best route between any two hosts.
(routers are like switches, but they can also bridge different networks .. in most home cases this means the internet and the local LAN)

turn off your PC

Turn ON your PC, and as soon as your BIOS POST screen disappears, press the SHIFT key and hold it, until you are presented with the GRUB menu .. SIMILAR to this:
(you won't have long to hit the shift key, and the timing can be a little awkward, so it may even be easier to hit AND HOLD the Shift key DURING the BIOS POST .. ie. immediately after turning on your PC)

(http://linuxforums.org.uk/MGalleryItem.php?id=1361)

Select the 'default' Ubuntu kernel (usually the top one), and rather than pressing enter, press E to edit.

You will be presented with a screen SIMILAR to this:

(http://linuxforums.org.uk/MGalleryItem.php?id=1152)

Press DOWN ARROW until you get to the line that starts with:

Quote
linux /boot


and press the END key to position the cursor at the end of the that line... it *usually* ends with “quiet splash”.

Now you can enter additional kernel boot options... so add the noapic option instead of nomodeset in the above screenshot .. so it now ends with:

Quote
quiet splash noapic

(doesn't matter if it moves down a line, as long as there is a space between splash and nomdeset)

Now hit Ctrl+X to boot.

Test ethernet and wireless speed.

This will only last for a single boot .. but if it helps, we can add it to GRUB permanently.

This morning I thought I stumbled upon the problem,  I've had problems since installing the Superhub connecting to my network printer so I decided to try and sort it out this morning and in doing so i discovered the reason I couldn't get it connected was because it was assigned the same IP as the problem PC (Linux4), creating a conflict, so I unplugged the printer left it a few minutes then connected it up again and it was re-assigned another IP address then I was able to connect to it, I hoped this would also sort out the download issue with Linux4 but unfortunately it hasn't but it has made it more stable, I'm not sure if this was worth mentioning but it might put a different light on the situation.

Another thing I was wondering was, would something like Wireshark or Backtrack help us nail down the problem, just a thought

Also could the answer lye here http://www.hitxp.com/articles/software/ubuntu-fix-slow-wireless-internet-connection-speed-upgrading-11-04-natty-narwhal/ (http://www.hitxp.com/articles/software/ubuntu-fix-slow-wireless-internet-connection-speed-upgrading-11-04-natty-narwhal/)

Why don't you give everything static IP's ?

I can't see how it would be wireless power management, as the connection through ethernet is still pants.

But can't hurt to try the 2 suggested solutions.

You *should* be able to .. what's the make/model ?

If you can't you'll want to change the range of IP's available to the DHCP server in the superhub.
(actually, do this anyway)

So lets say the router is 192.168.2.1 .. and you're going to give your PC's network interfaces static IP's of say

192.168.2.2
192.168.2.3
192.168.2.4
192.168.2.5
etc.

Set the routers DHCP server address pool to say the range -

192.168.2.100 - 192.168.2.254

So the DHCP server CANNOT hand out IP's that conflict with the static ones.

Also I'd normally set the DNS server to the IP of the router .. but IIRC, this didn't work with BkS's virgin superhub, and he had to do what you're doing.

Up to you -- I'd try the routers IP first.

I haven't set the IP pool in the router yet should I have done that first ?
Title: Re: Slow download
Post by: Mark Greaves (PCNetSpec) on July 20, 2013, 08:31:57 pm
YES, but it can wait for as second .. you obviously have a connection :)

Try this ....

Close the Networkmanager editor.

Open a terminal, and run:
Code: [Select]
gksudo nm-connection-editor

is the Save button still greyed when you enter the virgin DNS's as

192.168.4.100, 192.168.8.100

or even better, the IP of the router .. if it will work

?

That's the settings I'm putting in, I just done the same settings in Linux2 using the router IP for "DNS Server" and it saved it ok

ps What was Linux4 is now Linux 2 I changed the hostnames :)
Title: Re: Slow download
Post by: Mark Greaves (PCNetSpec) on July 20, 2013, 08:41:08 pm
That's not the important part of my last response .. it was the starting nm-connection-editor as root ;)

also, if the editor allows you to save .. try the routers IP as the DNS server
Title: Re: Slow download
Post by: Emegra on July 20, 2013, 08:48:19 pm
Sorry Mark I missed that post, that worked perfectly thank you

can you explain to me why I had to go in via root on this PC when I didn't have to on the other 2 ?

Just curious :)
Title: Re: Slow download
Post by: Mark Greaves (PCNetSpec) on July 20, 2013, 08:51:04 pm
Dunno for sure .. I get that occasionally .. so it must be a bug in networkmanager .. it SHOULD prompt for a password, but sometimes doesn't  :o

Sorry I should have said, yes it accepted router Ip on all 3 PC's

One thing I should do before I set router ip pool, is set printer IP, but I'm not really sure how to do that or is it worth the effort ?
Title: Re: Slow download
Post by: Mark Greaves (PCNetSpec) on July 20, 2013, 09:01:33 pm
Up to you .. I do, that way you always know its IP, and if for some reason DNS fails, you can still access it by IP.

But your call

I have static IP's for everything (all PC's, xboxes, printer, NAS) .. but still have a small DHCP pool for smart phones, etc.

OK as it turned out I had to set each PC's DNS Server to the Virgin DNS addresses and reboot because although I had a network connection I had no internet on any PC now I have a painfully slow internet connection on all PC's (albeit better than no connection at all) except my PC  which will not save in the network connection manager and has decided in it's infinite wisdom not to accept the terminal command  gksudo nm-connection-editor

slowly losing the will to live
Title: Re: Slow download
Post by: SeZo on July 20, 2013, 10:00:16 pm
Try to set the DNS Server to OpenDNS IP adress (instead the router or Virgin nameserver) on the PC with slow connection:
208.67.222.222
or
208.67.220.220

You could manually (as root) edit the stored networkmanager profile

Code: [Select]
sudo gedit /etc/NetworkManager/system-connections/"Network Emegra"

You have to edit it with root permission .. you can't even read it as anyone else

the above command assumes the connection is called Network Emegra .. and will need adjusting if it's called something else ;)

BTW, you REALLY need to get into the habit of not using spaces in names in Linux .. it *can* handle them, but it's easier if you steer clear of them ;)

ok this has got to the stage where I can't even describe the problems I'm having anymore, but to try to sum it up after setting all PC's to static IP address and setting the DNS Server settings to the router IP address left me with no internet, I then had to set the DNS Server to the virgin DNS addresses which give me an incredibly slow internet connection an all PC's except this one which give me no internet connection at all because it wouldn't allow me to change the settings because of a bug that happens to affect this PC and no other even though I used the same installation disc to install all PC's, and in addition to that it has decided it doesn't want to let me access the network editor in root by not accepting the terminal command "gksudo nm-network-editor" , anyway the incredibly slow internet connection rapidly turned into no internet connection at all on any PC or laptop (that hasn't even been touched) suggesting the the router is now screwed up  so I reset the router to factory defaults expecting to to get the default network showing up (as virginmedia8286556)  but instead I get Network Emegra (the connection I created) so explain that if you can, but at least it lets me post this message.

So I've had enough I'm not gonna try to sort this anymore but I would like to thank everyone whose tried to help me with this especially Mark whos perseverance and patience goes beyond the call of duty :)


Many thanks

I haven't much experience with the Superhub .. but normally to do a FULL reset, you need to hold the reset button for about 30 seconds

Some routers even require that you turn OFF the router, hold the reset button .. then turn ON the router whilst still holding the reset button for a few seconds.

But if it's working....

See above for a workaround for the one that won't let you make changes in networkmanager.

Networking remains somewhat of a black/mysterious art (in Windows too) .. even though it shouldn't be  :o

Did you try the openDNS servers ?

Another suggestion may be to try putting all PC's back to how they were .. just try a static IP (with the openDNS server) on the slow one .. as SeZo suggested.

I've had a few beers tonight and i'm just so frustrated with all this I'm going away on a weeks holiday from Monday and spend some quality time with my grand-daughter so it's probably best left till after that, please don't think i'm being ungrateful, I think computers have a habit of bringing out the worst in people and I suppose I'm no exception.

Thank you Mark I intend to

I had another go at setting static IP addresses to the PC's and Laptops this morning and I've finally managed it, I've used the openDNS addresses but then discovered there is no facility to set these addresses in the superhub http://community.virginmedia.com/t5/Other-Queries/Why-do-Virgin-suppress-the-ability-to-set-the-DNS-servers-on-the/td-p/411029 (http://community.virginmedia.com/t5/Other-Queries/Why-do-Virgin-suppress-the-ability-to-set-the-DNS-servers-on-the/td-p/411029)
so the question is, is there any point in me using openDNS am I gaining any benefit or am I just making things worse, I've set the dhcp pool to 100-254 as you suggested but I still don't know how to give the printer a static ip address.



Many thanks

Post by: Mark Greaves (PCNetSpec) on July 21, 2013, 11:25:46 am
Dunno if this is possible somehow in Linux .. but in Windows you use an application called SetIP

see page 34 here:
http://downloadcenter.samsung.com/content/UM/201107/20110722094633890/EN/english.pdf (http://downloadcenter.samsung.com/content/UM/201107/20110722094633890/EN/english.pdf)

But once the IP is set it doesn't matter what OS is used .. so you may have to use a windows PC to set the static IP.

If you haven't got a Windows PC, let us know and we'll see if there's a way to do it within Linux.

On most printers it can be achieved on the printer itself, by use of the configuration buttons .. but samsung seem to have had a brain fart moment where Linux is concerned  ::)

SetIP (for Windows) can be downloaded here:
http://downloadcenter.samsung.com/content/SW/201108/20110811153648878/SetIP_V1.05.03.exe (http://downloadcenter.samsung.com/content/SW/201108/20110811153648878/SetIP_V1.05.03.exe)

Well to get back on track I've set all PC's on my network to static IP and everything is fine except for the offending PC which is still only giving me around 1 mbps download speed, we've covered a lot of ground on this without success so is there any point in pursuing this any further, because I don't want to waste anybodys time

It would be handy (now) to see how a LiveCD/LiveUSB compares.

Here's an idea .. is this system simply at the boundary of it's resources ? .. with the web browser open and running the speed test .. whats the output from:
Code: [Select]
top
hit Ctrl+C to stop top from running, so you can copy/paste the output.

also what's the output from:
Code: [Select]
free -m
Also run whilst doing the speedtest

Also the same outputs whilst downloading something may be informative too

Yeh, it tells me your download speed sucks ;)
(and it aint the browser)

This is an odd one this ..

a) router and external connection must be OK if other PC's aren't slow
b) wireless has been pretty much ruled out if it was slow on ethernet too
c) IP conflicts have been ruled out by using static IP's

So as far as I can see, it MUST be sommat in the OS itself .. which is why I'd like to try PM3 .. maybe the earlier idea (that we never got to test properly, did we?) of turning PM3 into a PM4(alike)

Try a LiveCD of peppermint 3 again, and see what speedtest reports.

Post by: Mark Greaves (PCNetSpec) on July 21, 2013, 08:04:37 pm
I was just more interested in whether another distro with an earlier (substantially different) kernel would have made a difference.

If you've tried Zorin and it's based on the 3.2 kernel, and is still useless (even on an ethernet cable), then I'm gonna have to say this is probably a lost cause :(

I suppose testing from a Live session would rule out the HDD I/O as a factor ???

I'm inclined to agree, some things are just not fixable or explainable and I think this is one of them.to be honest the PC's not worth the effort I bought it for £12 out a boot sale to use as a NAS I only tried to make a PC out of it because the wifes PC packed up and I thought I could make it  do her as a stop gap till we got her something better, the sad thing is in every other respect it's really quite a fast PC and runs well on PM4, far better than her last PC ran on Windows.

But I have her converted I put PM3 on her Lenovo laptop because Windows 7 was driving her insane and she loves it

Lets put this to rest

Many thanks for your efforts

Women can be strange creatures SeZo, but in my case she just couldn't argue with the speed difference her laptop running W7 was a joke and I genuinely tried everything I knew to make it run better, one day she shut it down in disgust and said something like "I'm fed up of this laptop it's like watching paint dry" so i said well I can make it run faster if that's what you want but not with that OS, her reply "do what you have to do I don't care"



So I did and she hasn't looked back

That's the trouble with you smart computer guys, you can fix computers properly so when your missus Windows computer does the Windows thing and run slow and generally screw up you can fix it properly I can't I can only do what I know which is pretty limited and to be honest I don't really know if there was anything wrong with her laptop as such but it was slowish but there's no doubt Linux woke it up

Underpowerred power supply is about the only other thing I can think of as a possibility .. nothing jumped out in dmesg besides the connection seeming to drop out and reconnect a lot.

@Emegra .. did you say earlier that other things you connected to the USB ports also went screwy (such as an external HDD, or USB stick) unless they were connected to a powered hub ?

Yes but I can't remember the exact details but it was when I was transferring terminal outputs using a USB stick the hub went down but it wasn't the hub itself it was the USB card the the hub was plugged into, I had to switch things around so the hub was plugged directly into the main motherboard USB ports, as it stands now there are 2 PCI USB cards but one is redundant

The hub isn't a powered hub although it uses 2 ports I have a Belkin usb adaptor plugged in to it at the moment which is working and seems stable whereas the PCI card works when it likes

Hmm .. could either be power related .. or if you have internal hardware that's playing up like that PCI/USB card it's always best to remove it and see if things improve.

Old power supplies tended to be very weak .. bung an extra 2 PCI card in and things could start to play up.

Here's what I'd do..

If you have a higher rated power supply .. try it

Remove ALL redundant and especially possibly broken hardware such as the PCI/USB adapters that are playing up .. one broken component can effect the entire system .. I've seen plenty of old no longer used PCI modems bring systems down when they've failed quietly.
(plus we're trying to take as much strain off the power supply as we can)

Use the PCI wireless card not USB .. the PCI/USB cards were probably fitted due to a lack of USB2.0 on the motherboard (?)

Ok I'll try that when I get home I'm on holiday and on a public wifi at the moment and my problem internet connection at home seems like lightening by comparison, anyway I dont understand why I didn't remove the  PCI card myself when I realised it was faulty because I once had a faulty USB card before that brought the whole system to a grinding halt so you just might be on to something


Many thanks

Just to close this thread

I removed the suspect USB card and fitted another power supply and it's just the same although it wasn't a new one I can't see 2 power supplies doing the same thing so I think we can safely say we've exhausted every avenue, and put it to rest

Many thanks to Mark and Sezo for you gallant efforts

some things are just not meant to be
