Ubuntu 11.10: non funziona wireless scheda di rete Broadcom BCM 4311
#1
Sono nuovo di Ubuntu e lo sto provando (con soddisfazione) in modalità cd live sia sul pc fisso di casa che sul portatile. Nel primo caso tutto ok, mentre nel secondo ho un problema con la scheda di rete wireless come da titolo: andando nelle impostazioni della connessione in alto a destra si legge "Wireless network (Broadcom BCM 4311 802.11b/g WLAN): device not ready (firmware missing). Ho provato molte possibili soluzioni trovate su internet per installare il firmware ma non ci riesco proprio... Potete aiutarmi per favore?

Tenete conto che se uso invece un adattatore usb wireless (quello fornito con il mio router, un Linksys WAG200G) la connessione wireless funziona perfettamente, dunque il problema è proprio soltanto della scheda di rete, che invece in Windows funziona bene.

Posto un po' di risultati da terminale, al limite ditemi voi se avete bisogno di altro:

Nessun aiuto? CoolHuh

Ciao, delle due wlan che si vedono con ifconfig -a una è quella dell'adattatore vero? E' configurata con un IP valido, quindi suppongo che la wlan0 sia quella "incriminata" e che risulta disabilitata.

Hai provato ad attivarla tramite il comando

sudo ifconfig wlan0 up

Ogni fallimento avvicina sempre più alla meta... Arrendersi subito equivale a non provare affatto.

Ma sbaglio o sono sparite alcune risposte in questa discussione? C'è stato qualche problema nel forum? Huh

Si, un problema con il database. Puoi riassumere fino a che punto eravamo arrivati?

Vado a memoria, dovrei aver risposto il giorno che c'è stato il problema e il forum è stato ripristinato al giorno prima.
Consigliavo questa pagina https://help.ubuntu.com/community/WifiDo...er/bcm43xx e in particolare mi sembrava calzante questo punto:
Step 1.
To install b43-fwcutter issue the following command in a terminal (under the desktop menu Applications > Accessories > Terminal) and follow the prompts:
~$ sudo apt-get install b43-fwcutter
Since Ubuntu 11.04 Natty Narwhal additional installation of the package firmware-b43-installer can be helpful and/or necessary, respectively:
~$ sudo apt-get install b43-fwcutter firmware-b43-installer
or, if you need a legacy driver, use:
~$ sudo apt-get install firmware-b43legacy-installer

Poi ho fatto lo step 2:
Step 2.

Under the desktop menu System > Administration > Hardware/Additional Drivers, the STA drivers can be activated for use.

Note: In Ubuntu 11.04, if the driver fails to load, you may need to reinstall the bcmwl-kernel-source package. This can be done from Synaptic -> Mark for Reinstallation.

Note: A computer restart may be required before using the wifi card.


E poi lo step 3, essendo su Liveusb:

Step 3.

Instead of a computer restart, in a terminal issue the following commands:

~$ sudo modprobe -r b43 ssb wl
~$ sudo modprobe wl


Ma a questo punto il terminale non dà nessun risultato, e se disconnetto l'adattatore usb wireless esterno che sto usando al posto della scheda di rete interna sono senza rete. Davvero non so più cosa fare, l'adattatore usb esterno funziona ma è scomodo... Big GrinBig GrinBig Grin

Prova a scaricarlo da qui

P.S. Ma in "Driver Aggiuntivi" non ti compare la scheda?
