Linux Mint 14 / Ubuntu 12.10 Slow Wifi with Ath9k Drivers + Solution

I upgrade my laptop to the latest release of Linux Mint 14 MATE edition. Everything is working beautifully apart from the wireless which, whilst functional, was cripplingly slow.

After a load of searching and testing, the solution that worked for me was:

sudo -s

iwconfig wlan0 rate 54M

echo "options ath9k nohwcrypt=1" > /etc/modprobe.d/ath9k.conf


If you copy and paste the above into a terminal it will force the wifi speed to 54M and will make sure hardware crypt is disabled and finally reboot your machine.

I did this and my wifi speed is now perfectly fast, I’m a happy bunny :)
