Bug#493832: ath5k disconnects regularly and has poor performance
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.
