Comment 15 for bug 535222

Actually #8 worked just for the system to create the interface ath0, but wireless network performance is quite bad, slow and unstable. Rather I came back to the new ath9k driver and installed wicd on slackware 13.1.
Now, ath9k is loaded on boot time, wlan0 is then created and wireless network is working properly and fast, just like it used to be on windows.
I am even able to connect through command line (wpa_supplicant and dhcpcd wlan0), using, wifi-radar or wicd, all these methods work very well.

Slackware 13.1 linux 2.6.33.4, atheros ar9285
SOLUTION: ath9k driver

have fun
