Nefunguje wifi

[Übermensch]

Network Manager mi hlásí, že "bezdrátová síť je zakázána hardwarovým přepínačem", i když to není pravda.
V 10.10 mi to funguje, ale v 11.04 už ne. Čím to je?

Co ukazuje například lspci nebo dmesg?

log dmesg je velmi dlouhý, ale všiml jsem si tohoto:

Na tamtu stránku jsem se koukl, ale nevím, co si mám stáhnout, o ucode15.fw tam nikde není ani zmínka.
