Until today’s kernel update to 188.8.131.52, the Atheros wifi card was not functioning correctly. Since the update to new kernel, the wifi card can now be used with the ath5k module which can be found in linux-backports-modules.
In order to get the Atheros 5007EG card to work, you first need to disable the built-in hardware driver.
System >> Administration >> Hardware Drivers > Deactivate “Support for Atheros 802.11 cards”
After the card has been deactivated, open the terminal and install the backports modules for Jaunty.
sudo apt-get update && sudo apt-get install linux-backports-modules-jaunty
This adds the ath5k module which supports the Atheros 5007EG card.
The computer needs to be Shutdown and powered back on. Somehow Restarting doesn’t work at times. The card has to be completely powered down for a few seconds and then started during power up.
You should be able to see the available wireless network list by clicking on the network manager icon. Thereon, you all know what to do 🙂
