    Exclamation [SOLVED] Dell Wireless Hard Blocked

    Hi,

    The wireless on my Dell Inspiron 1018 (Dual booted Windows and Ubuntu) seems to have stopped working after I pressed the wireless button (F2) on the keyboard.

    Pressing it again does not seem to re-enable it.

    This has happened before and booting it into Windows and press F2 normally re-enables the wireless.

    This time, however, (after updating to 12.04) the wireless is disabled again when I boot back into Ubuntu.

    Here's my outputs:

    rfkill list
    Code:
    me@sInspiron-1018:~$ rfkill list
    0: hci0: Bluetooth
    	Soft blocked: no
    	Hard blocked: no
    3: phy0: Wireless LAN
    	Soft blocked: no
    	Hard blocked: yes
    4: dell-wifi: Wireless LAN
    	Soft blocked: yes
    	Hard blocked: yes
    5: dell-bluetooth: Bluetooth
    	Soft blocked: no
    	Hard blocked: no
    (Interestingly, after I enable the wireless in Windows and go back to Linux, dell-wifi hard blocked is listed as no. Despite this, phy0 is still hard blocked and the wireless is still disabled)

    iwconfig:
    Code:
    me@sInspiron-1018:~$ iwconfig

    I have tried (thanks to some of the advice in other threads)

    1) As mentioned above, booting into Windows and pressing the hardware switch - which works until I boot back into Ubuntu.
    2) rmmod dell-laptop and then attempting to unblock/press the switch
    3) Reinstalling my wireless driver rtl8192ce

    Any help or advice would be greatly appreciated.

    Thanks

    Re: Dell Wireless Hard Blocked

    Is there maybe some small and hidden non-keyboard switch on the case?
    The "hard-locked" means a mechanical switch locked it.
    HP laptops have that switch on a weired spot making it easy to switch it w/o noticing, maybe you have something like that as well.

    Thanks for responding

    I have had a quick look around the laptop for any other switches but I can't seem to find anything.

    When I go into Windows the wireless is disabled until I press F2 which is what made me think that it was this switch that was the problem.

    I think the windows driver has a part in this.

    Does the windows driver influence the Linux drivers? Or does it not fully unblock the wireless card?

    Re: Dell Wireless Hard Blocked

    Please try:
    Code:
    sudo modprobe -r dell-laptop
    sudo rfkill unblock all
    rfkill list all
    Any improvement? If so, let's blacklist dell-laptop:
    Code:
    sudo su
    echo "blacklist dell-laptop" >> /etc/modprobe.d/blacklist.conf
    exit
