[Risolto] [Wireless] scheda wifi /Wireless 3945ABG [Golan] Network Connection non si attiva

[marilux]

sono proprio agli esordi con linux ,ho installato ubuntu 11.04 su usb 8gb, e la uso su un notebook fujitsu siemens con 3gb ram e windows vista home premium. Tutto sembra funzionare, ma la scheda di rete wifi proprio non si vuole attivare, il led della scheda rimane spento, sotto vista l' accendo con due tasti funzione (l'unico modo) e funziona . Ho provato i più disparati comandi da terminale ma non riesco a venirne a capo ho eseguito la seguente procedura:
$ wget http://intellinuxwireless.org/iwlwifi/d ... 32.2.9.tgz

$ tar xzf iwlwifi-3945-ucode-15.32.2.9.tgz

$ cd iwlwifi-3945-ucode-15.32.2.9

$ sudo cp iwlwifi-3945-2.ucode /lib/firmware

$ sudo reboot

ma nulla da fare vi posto un po' di risultati ad alcuni comandi da terminale:

attendo vostro aiuto grazie

Ciao e benvenuto

da terminale

Codice: Seleziona tutto

rfkill list

posta l' output

posta gli output all' interno dei tag di codice :#

Codice: Seleziona tutto

così si leggono meglio
e occupano meno spazio

[marilux]

ecco qua

Codice: Seleziona tutto

ubuntu@ubuntu:~$ rfkill list

ubuntu@ubuntu:~$

Codice: Seleziona tutto

[isuaami]

da terminale

Codice: Seleziona tutto

rfkill unblock all

dovrebbe attivarsi

mi spiego meglio per gli output:
click su #
incolla l' output tra  (code) e (/code)

Codice: Seleziona tutto

così
