Wifi device not ready, but it isn't hard nor soft blocked

  • 772

I'm unable to connect to wifi on my Toshiba Satellite U200, even though the wireless card doesn't seem to be blocked:

$ rfkill list
0: Toshiba Bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: yes
6: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no

Note: when I boot it is blocked, but doing:

modprobe -rfv iwl3945
rfkill unblock all
modprobe -v iwl3945

Unblocks it. The led doesn't get turned on. Using the hardware keys doesn't change anything.

The output of lshw is:

$ sudo lshw -C network

Does anybody know what's the problem and how to fix it?

  1. Okay, I got it. There was an small hardware switch on the side that was turned off. This is indicated by the dmesg:

    [ 1336.469707] iwl3945 0000:02:00.0: Radio disabled by HW RF Kill switch

    However I have no idea why rfkill list says hard blocked: no...
