If you have an Atheros AR9285 wireless card on Ubuntu 9.04 and cannot get it working, this is for you.
Ubuntu did not automatically detect my card (AR9285) and spent many hours trying to figure this out. The purpose of this is to show you how to get your Atheros AR9285 Wireless Network Adapter working without those many hours of finding the wrong answers.
It is very simple.
Download a stable release (I downloaded compat-wireless-2.6.30.tar.bz2) from the following website to your desktop:
http://linuxwireless.org/en/users/Download/stable/
Open up Terminal and type:
(It tells you all this on the website that you download it from.)cd Desktop
tar -xf compat-wireless-2.6.30.tar.bz2
cd compat-wireless-2.6.30
make
sudo make install
sudo make unload
Restart.
Click on the wireless icon in the top right corner of the screen and logon to your wireless network.
Fin!
Edit: Apparently the bleeding edge drivers are faster. I have not tested them though.
