Vážení, požívám Kubuntu 8.04 2.6.24-21-generic plně updatován. Instalováno na notebooku HP Compaq nc6320 a mám problém s WiFi kartou Broadcom 4311, kterážto je součástí tohoto notebooku.
Po startu karty vše naběhne jak má. Využije se konfigurace z "/etc/network/interfaces" a "/etc/wpa_supplicant.conf" k nastavení správné sítě a autentifikace. Bohužel po nějaké době (a to se velice různí po jaké) dojde o odregistrování WiFi od AP. V dmesg se to projevuje následovně:
dmesg | grep -e wlan

Po restartu wlan0 (Ifdown wlan0; ifup wlan0) vše zase naběhne jak má ( na nějakou dobu).
Netuší někdo co s tím? Vše ostatní chodí OK, ale stále restarty wlan0 docela degradují práci se systémem.
Použití ndiswrapperu není možné, neboť se vůbec nespojí na WPA. Jediné trochu funkční řešení co jsem našel je to které mám, resp. na jiné jsem zatím nepřišel.
Díky za navedení či radu už se s tím trápím několik dní.
