Não consigo me conectar ao Wi-Fi em meu Toshiba Satellite U200, mesmo que a placa sem fio não pareça estar bloqueada:
$ rfkill list
0: Toshiba Bluetooth: Bluetooth
Soft blocked: no
Hard blocked: yes
6: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
Nota: quando eu inicializo, é bloqueado, mas fazendo:
modprobe -rfv iwl3945
rfkill unblock all
modprobe -v iwl3945
Desbloqueia. O led não fica ligado. Usar as chaves de hardware não muda nada.
A saída de lshw é:
$ sudo lshw -C network

Alguém sabe qual é o problema e como consertá-lo?
Ok, eu entendi. Havia um pequeno interruptor de hardware no lado que estava desligado.
Isso é indicado pelo dmesg :
[ 1336.469707] iwl3945 0000:02:00.0: Radio disabled by HW RF Kill switch
No entanto, não faço ideia do porquê rfkill list diz hard blocked: no ...
