WLAN Hardware-Switch or Card defective??

[erix]

Hello,

since yesterday, I think that the WLAN-Hardware switch or the card of my girlfriends Lenovo is defective.
The WLAN-LED is on, the hardware-switch is on. But the Network-Manager says that the WLAN is deactivated by hardware.

So I ran 2 tests. Test 1 with WLAN-Switch off:

Code: Select all

sabayon nancy # iwconfig
lo        no wireless extensions.

wlan0     IEEE 802.11abgn  ESSID:off/any 
          Mode:Managed  Access Point: Not-Associated   Tx-Power=off   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
         
sabayon nancy # rfkill list
0: ideapad_wlan: Wireless LAN
        Soft blocked: yes
        Hard blocked: yes
1: ideapad_bluetooth: Bluetooth
        Soft blocked: yes
        Hard blocked: yes
2: phy0: Wireless LAN
        Soft blocked: yes
        Hard blocked: yes

Than the 2nd test with WLAN-Switch on:

Code: Select all

sabayon nancy # iwconfig
lo        no wireless extensions.

wlan0     IEEE 802.11abgn  ESSID:off/any 
          Mode:Managed  Access Point: Not-Associated   Tx-Power=off   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
         
sabayon nancy # rfkill unblock all
sabayon nancy # rfkill list
0: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no
1: ideapad_wlan: Wireless LAN
        Soft blocked: no
        Hard blocked: no
2: ideapad_bluetooth: Bluetooth
        Soft blocked: no
        Hard blocked: no
3: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: yes

What is wrong with the hardware?? Is it truely defective?
Is there another possibility to check the hardware.

Tanks in advance for tipps.

(It's a Lenovo Idea-Pad U350)

See if the thread Can't enable wireless - RF_KILL problem? [Solved] helps you.

Unfortunately that wasn't the solution. I also tryed the WLAN-Connection with the Sabayon Live-DVD. It's just the same problem: "WLAN deaktivated via Hardware".
So it seems that the network-adapter is really defective. Also the LAN-Connection is without any function.
The only thing that works now is network via UMTS-USB-Stick.

Shit...
