Ich habe ein Problem mit WLAN auf meinem Laptop Lenovo Ideapad Y580 (gekauft mit vorinstalliertem Windows 7 Home Premium 64bit). Nach der Deinstallation von Win7 und der Installation von Ubuntu 13.10 64bit (wo normales kabelgebundenes Internet funktioniert) funktioniert WLAN nicht!
Drahtlos wird durch Hardware-Schalter deaktiviert.
rfkill liste alle auf
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
Ich habe das BIOS überprüft und die WLAN-Karte ist dort aktiviert.
Fn + F5 hat nicht funktioniert und mein Computer hat außen keinen physischen Schalter, weshalb ich hier gefragt habe.
rfkill unblock all
ändere nur weiche Blöcke und sudo ifconfig wlan0 up
zeige mir folgendes : SIOCSIFFLAGS: Operation not possible due to RF-kill
.

Wie kann ich dieses Problem lösen?

sagt, meine Ethernet-Brücke ist deaktiviert. Hat das mit deinem Problem zu tun?
