Atheros QCA9565 / AR9565, Ubuntu 12.04

[Liis]

Hello!


So I have similar problem like many others. I update my laptop and after that it won't connect do wifi anymore. I have search forums, try to do different stuff, but still it doesn't work. Ubuntu is new for me so it's kinda difficult to operate by myself. Can somebody help me, please?

Please open a terminal Ctrl+Alt+t and run and post:

lspci -nn | grep 0280
rfkill list all

The pipe symbol | is on the right side of my US keyboard on the same key with \. Thanks.

Deactivate the hardware encryption of the driver:

echo "options ath9k nohwcrypt=1" | sudo tee -a /etc/modprobe.d/ath9k.conf
sudo modprobe -rfv ath9k
sudo modprobe -v ath9k

Hope I did it right.

So, lets check now:

dmesg | grep ath
iwconfig
ifconfig -a
cat /etc/resolv.conf
iwlist chan
sudo iwlist scan

I recommend changing the encryption to pure WPA2-AES (CCMP), check the router manual.
