Ahoj, mám problém zřejmě s drivery síťové karty. Pro wifi připojení mám miniPCI Broadcom BCM43228 802.11a/b/g/n. Po aktualizaci systému Ubuntu mi z nastavení vlastně úplně zmizela záložka wifi a nemohu se bezdrátově připojit. Pár věcí už jsem zkusil, ale zatím nic nepomohlo. Někdo nějaké rady?

nevidím , že by wifina mala natiahnutý "Kernel driver in use: bcma-pci-bridge"
takže ešte výpis :lsmod | grep b43
ls /lib/firmware/b43
ls /etc/modprobe.d

Zkusil jsem bootit systém se starším Grubem a wifi ve starší verzi systému funguje. Takže to tak prozatím nechám. Kdyby cokoliv vložím sem další komentář. Děkuji!

Prosime trochu obsirneji.
Jaky grub byl pred tim a jaky je ted ten funkcni?
Postupoval si preinstalaci baliku grubu nebo si pouzil starsi verzi Ubuntu nebo co mas za OS? V takovem pripade verze OS s kterou to nefungovalo a verze OS s kterou to funguje?
Nahlasil si chybu na bugreport OS?
