J'ai un problème avec le wifi sur mon ordinateur portable Lenovo Ideapad Y580 (acheté avec Windows 7 Home Premium 64 bits préinstallé). Après avoir désinstallé Win7 et installé Ubuntu 13.10 64 bits (où Internet filaire normal fonctionne), le wifi ne fonctionne pas!
La connexion sans fil est désactivée par un commutateur matériel.
rfkill liste tout
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
J'ai vérifié le BIOS et la carte sans fil y est activée.
Fn + F5 n'a pas fonctionné et mon ordinateur n'a pas de commutateur physique à l'extérieur, c'est pourquoi j'ai demandé ici.
rfkill unblock all
changer seulement blocs mous, et sudo ifconfig wlan0 up
me montre ceci: SIOCSIFFLAGS: Operation not possible due to RF-kill
.

dit que mon pont Ethernet est désactivé. Est-ce lié à votre problème?
