My card worked correctly with Madwifi in Etch (stable). Lenny (stable) replaced
it by ath5k and is really bad.
Also it worked bad in other distributions with a kernel more updated. It was a
chaos until I discovered the problem: ath5k.
The speed and response of the ADSL connection are terribly bad with ath5k, nor
approach a modem of 56 KB, although it does not become disconnected. I did not
obtain better results when I deactivated IPv6 in the system and web browser.
Lamentably I must use propietary driver.
Regards.
