Ho un problema con il wifi sul mio laptop Lenovo Ideapad Y580 (acquistato con Windows 7 Home Premium 64bit preinstallato). Dopo aver disinstallato Win7 e installato Ubuntu 13.10 a 64 bit (dove funziona la normale rete cablata) il wifi non funziona!
La connessione wireless è disabilitata dallo switch hardware.
rfkill elenca tutto
martin@martin-Y580:~$ rfkill list all
0: ideapad_wlan: Wireless LAN
Soft blocked: no
Hard blocked: no
1: ideapad_bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
Ho controllato il BIOS e la scheda wireless è abilitata lì.
Fn + F5 non ha funzionato e il mio computer non ha un interruttore fisico all'esterno, motivo per cui ho chiesto qui.
rfkill unblock all
cambiare solo i blocchi morbidi e sudo ifconfig wlan0 up
spettacoli me questo: SIOCSIFFLAGS: Operation not possible due to RF-kill
.
Alcune specifiche:

Come posso risolvere questo problema?
lshw
dice che il mio bridge ethernet è disabilitato. Questo è legato al tuo problema?
