[gentoo-user] Atheros WLAN loosing link

[Enrico Weigelt]

Hi folks,


my Atheros wlan (builtin, internal intenna) is regularily 
loosing link. Reproducible in various different networks.
At home, my wlan ap is about 2 meter away (within the room),
so link quality (currently 53) shouldnt be the problem.

Does anyone know what could cause the problem ?
