How to get ath5k working on Jaunty with Compat-wireless and a self-compiled kernel

I used to have some trouble while setting up my Atheros PCI card on Ubuntu Linux 9.04. It worked natively on Ubuntu 8.04, where it was detected as ath0. I upgraded from 8.04 to 8.10 whereby I noticed my wireless PCI card didn’t work natively anymore. Someone suggested me to upgrade from 8.10 to 9.04 Jaunty, and I did that immediately. After the system upgrade I noticed again that my wireless device was gone in Ubuntu 9.04. When I ran iwconfig I didn’t see wlan0 or ath0 anymore.

Have you tried going to add a wireless driver to the system.
1)GO to Application-Add/Remove
2)Go to System Tools
3)Find/Checked Wireless
4)Load your adaptor driver
Hope this helps.
