problém z wifi na ubuntu 11.04
Zdravím, potrebujem nejaké riešenie tohto bugu: http://www.mail-archive.com/ubuntu-bugs@lists.ubuntu.com/msg2909385.html ktorý spôsobuje že wifi ide strašne pomaly a nestabilne, vypadáva signál atd. Skušal som nainstalovat toto: linux-backports-modules-net-natty-generic ale nepomohlo. Nejaké nápady ? diki

Vyzerá to na problém v jadre 2.6.38,
skús napríklad zakázať "power management" na tej wi-fi karte, čo to porobí ...
Napríklad : http://linuxos.sk/forum/20257/index.html#link_176706
Ešte si skontroluj, či sa ti nespráva systém ako tunaky, ked sa prechádza na baterky:
