Is it better that I format the MicroSD?
OK one step at a time…
What’s the output from:
cd ~/kernel-headers
then
sudo dpkg -i linux-headers-4.1.10-v7+_4.1.10-v7+-2_armhf.deb
I formatted the MicroSD and I restarted with

before
sudo dpkg -i linux-headers-4.1.10-v7+_4.1.10-v7+-2_armhf.deb
So you’ve done a fresh install ?
If so we’ll have to start from the beginning again … what’s the output from:
uname -a
I’ve done everything!!!
How could I see if everything works correctly?
But, when I boot the Raspberry it’s possible to read [ 5.575058] Error: Driver ‘r8188eu’ is already registered, aborting…
run:
echo "blacklist r8188eu" | sudo tee -a /etc/modprobe.d/blacklist.conf
then REBOOT.
Do you still get that message ?
After the above, what’s the output from:
lsmod

Do you still get the error message ?
does wireless now work ?
Yes,
everything works well.
Good job!
Hi,
I followed the instructions on the first post of this thread in attempt to get my old 32bit linuxcnc machine (debian wheezy based, 3.4.9-rtai kernel) connected to my wifi hub which is a BT Home Hub 2 I believe. The driver compiled, installed and gets loaded just fine but no matter what I try I cannot get the machine to authenticate with the hub. It sees the network but cannot connect. I tries but then just asks for the password over and over again. I’ve tried everything I can with the network settings and checked the password several times but no avail.
Strangely enough I can connect to my Raspberry Pi which I’ve set up as a WiFi access point for other purposes.
Any help would be appreciated.
Ta,
Kari
Try setting a static IP for your IPv4 profile in network manager.
Thanks for the quick answer. Unfortunately the result remains the same. The syslog below indicates some kind of timeout during authentication. Not sure what this means…
Just for sake of testing I plugged in the mini wifi usb dongle (rtl8192cu based) from my Raspberry Pi into this machine and it worked. However I’d rather get this D-Link GO-USB-N150 to work with it instead as it’s bigger and not really suitable for Raspberry Pi because of that.
Here’s the syslog. Hope it tells you something:

Appreciate your help!
will it connect if you temporarily (just as a test) disable wireless security in your router ?
and can you post the output from:
modinfo 8188eu
and
ls -l /lib/firmware/rtlwifi/rtl8188eufw.bin
and
sudo lshw -C network
[EDIT]
Bit Rates:130 Mb/s
There’s normally a list of possible connection speeds here…
Can you check if wireless in your router is set to wireless “N” only … if it is, try setting it to “B/G/N”
Ok. Getting some progress now. I was able to connect when I changed the security from wpa/wpa2 personal to none. The router was already set to 802.11 b/g/n so I didn’t change it. In the router’s settings page it also says “Actual data transfer speed 65 Mbps”. Not sure where the 130 came from…
Anyway here are the outputs you asked for:

What happens if you run:
sudo rmmod r8188eu
then
sudo modprobe 8188eu
are you then able to connect ?
if not, can you post the output from:
lsmod
Thanks for trying. My system does not have a module named r8188eu so the result of lsmod is identical to my reply #95.
I found a few other hits online regarding WPA/WPA2 authentication problems with Realtek chips in Linux. Few of them turned out to be a bug in the driver so I’ve raised an issue at GitHub. I will reply here if I get a solution to this.
