I have Compaq Presario C772TU Notebook PC which has Atheros AR5006X Wireless Network Adapter.
Last Saturday I installed Fedora 8 on my Laptop but WiFi was not working. After searching on the Internet I came to know that Atheros AR5006x has some issues with Linux.
I tried installing NDISwrapper and MadWifi but no Luck. I then mailed Fedora Testing Group and I got some responses from other member and my problem was solved.
Here are the steps.
1. Download this version of MadWifi.
2. Untar the downloaded Package.
3. Enter the extracted directory
4. Install MadWifi
make install
/sbin/modprobe ath_pci
/sbin/modprobe wlan_scan_sta
5. Restart of PC or Network
You should now see available networks in your network manager.
