Atheros Wifi - Problem Z Kernelem.

[Juve]

Na ostatnich trzech kernelach mam problem z połączeniem z wifi - czasami wstaje, czasami nie, zależy od humoru:)

Na domowym wifi, wszystko było ok do dzisiaj, a na uczelnianym eduroamie (Politechnika Świętokrzyska) zrywa połączenie od ostatnich trzech kerneli w zależności od humoru, a dziś (żadne aktualizacje nie były robione) nawet z domowym jest problem. Poniżej log z /var/log/messages

Domyślam sie, że chodzi o jakieś wysyłane ze stacji pakiety, ale o co głębiej to NIE MAM POJĘCIA.
