    Wireless not working on ThinkPad X220 / Intel Centrino Wireless-N 1000

    Dear all,
    I recently got a ThinkPad X220 on which I installed Ubuntu 12.04 64 bit.

    Everything works just fine except for the wireless.
    In the Systems Settings menu "Enable Wireless" is grayed out
    and I can't enable it, not even pressing FN+F5 (that on my laptop
    enables and disables the wireless).

    I don't know where to start to diagnose the problem and give you
    some more useful information, but I would be very grateful if you could help me solve this issue.

    Thanks a lot in advance for your help!
    Luca

    I honestly don't understand at all the output of these commands.
    If you figure out what it means, could you please also tell me what I checked and what the answers need (so I learn something, while fixing the issue).

    Thanks a lot again for the help!

    Thanks praseodym,
    here is the output (I see something has changed to soft blocked, but not
    to hard blocked).
    Code:
     sudo rfkill unblock all
     rfkill list

    Hi praseodym,
    unfortunately none of the 3 solutions listed in the post you linked has worked.

    The hard block is still set.

    Re: Wireless not working on ThinkPad X220

    Try to press Fn+F5 continously or permanently durin boot-up. Is it a dualboot-system? If yes, maybe Windows is shutting down the card?

    Re: Wireless not working on ThinkPad X220

    The machine has only Ubuntu on it and pressing FN+F5 during
    boot (both continuously or permanently) doesn't do anything.
