[RISOLTO] Problema wireless scheda broadcom BCM4318

[franceesco711]

Ciao, sono nuovo di linux, amici mi hanno convinto a provare un alternativa a windows e abbiamo optato per xubuntu 12.04
il mio problema è che non riesco a connettermi wifi ed ha cercare reti presenti nella zona in quanto nella pannello in alto andando a cliccare sull' elenco reti mi è impossibile spuntare l' icona con dicitura "abilita reti senza fili" ed il tasto presente sulla tastiera non da segni di vita, sebbene dal terminale digitando un comando (che non ricordo, kill qualcosa ) noto che premendolo e non premendolo le cose cambiavano e ho scoperto che in impostazioni>driver aggiuntivi è presente un driver broadcom senza fili inattivo che però non al momento dell attivazione mi fa crashare il pc

il modello del pc è un hp pavillion zd8000
grazie in anticipo

Per favore, posta l'output di questi comandi:

Codice: Seleziona tutto

rfkill list all
lspci -vnn
sudo lshw -C network

Se il tuo problema è una scheda Broadcom, sappi che non c'è nulla di difficile, sono solo un po' macchinose da impostare.

Ok, da questo output non è chiaro qual'è il tuo problema perchè hai sicuramente uno, forse due problemi. La prima cosa da fare è:

Codice: Seleziona tutto

sudo rfkill unblock all

e prova a connetterti. Se ci riesci, per favore faccelo sapere perchè ci serve per gestire eventuali casi simili in futuro. Se invece non ci riesci, è perchè hai il driver prorpietario della Broadcomm; in questo caso dovremo installare i drivers Open Source, che sono di gran lunga i migliori.

[franceesco711]

ciao, con il comando che mi hai dato non succede nulla, però ora sebbene non ci sia piu l opzione abilita reti wireless, il tasto che prima usavo per accendere il wifi, si illumina di nuovo...un buon inizio

[MariusMatutiae]

Bene, allora hai due problemi. Ora dai questi comandi, per favore:

Codice: Seleziona tutto

sudo apt-get purge bcmwl-kernel-source
sudo apt-get install firmware-b43-installer
sudo modprobe -r wl

Spegni, riaccendi, e per favore fammi sapere.

[franceesco711]

buona, non ho ben capito se l'ultimo comando è stato eseguito correttamente ma ora funziona tutto ; grazie mille

[giulux]

se non hai più problemi modifica il titolo del primo post premettendovi [Risolto]
ciao

[MariusMatutiae]

Permettimi, Giulux, io vorrei chiedere una diversa modifica del titolo. Io proporrei una cosa del tipo: "RISOLTO" Problema wireless scheda broadcom BCM4318. Questo aiuta la ricerca della soluzione da parte di eventuali altri utenti con problemi simili. Grazie.

non ho seguito la discussione
se il titolo proposto corrisponde al contenuto, va bene

Scusate il ritardo; modifico subito seguendo il suggerimento.
grazie ancora
