A occhio mi sembra una scheda supportata dal modulo b43, potresti provare a usarlo al posto del modulo broadcom-sta.

Installa i pacchetti necessari:
(come root)

Code: Select all

equo install b43-fwcutter b43-firmware


Rimuovi i driver broadcom-sta:
(come root)

Code: Select all

equo remove --configfiles broadcom-sta


Permetti al kernel di caricare il modulo b43, apri il file /etc/modprobe.d/blacklist.conf, trova la linea:
# make broadcom-sta happy

Cambia quel paragrafo in questo modo:

Code: Select all

# don't use broadcom-sta
blacklist wl
# blacklist ssb
# blacklist bcma
# blacklist brcmsmac
# blacklist b43


Ora riavvia e controlla se la tua scheda di rete funziona.

Ciao.. scusa se rispondo solo ora ma non ho avuto molto tempo in questi giorni..
Ho notato che il pc, una volta che stacco l'altenna esterna, inizia a far funzionare la sua antenna wifi.. il che mi lascia un po' perplesso.. non so cosa possa essere a questo punto.. il driver funziona immagino.. forse non riesce ad avviare il processo da solo e vuole, diciamo, una spinta.. boh.. comunque visto ha ricominciato a funzionare, non ho fatto tutte quelle operazioni che mi hai scritto.. non mi sembrava il caso.. visto che bene o male ora funziona.. comunque grazie mille per l'aiuto.. siete sempre così disponibili..

Riuppo questo topic perchè ho lo stesso problema! Si è piantata la wireless dopo un aggiornamento.... Ho sabayon X con kernel 3.7. Posto i risultati di ifconfig, lsmod e lspci -v:

In questo forum gli "up" non sono considerati troppo educati, a mio avviso sono un pessimo retaggio dei forum di Ubuntu.
