    Wireless Trouble [hard block]

    I used Lenovo 370, my wireless suddenly not working properly. When I checked in rfkill there's a hardblock in phy0. I already turn on the wireless switch, even tough in BIOS setting. I already unblocked all but the hard block still appears. When booting I was seen the wireless light indicator ON, but the light suddenly OFF in logon screen.

    uname -a
    Code:
    Linux notebook 3.0.0-16-generic #29-Ubuntu SMP Tue Feb 14 12:49:42 UTC 2012 i686 i686 i386 GNU/Linux

    In the terminal look at the output of

    lsmod

    (LSMOD in lowercase) and see if a module exists called acer_wmi ( for some reason Lenovo's often seem to have it)

    If it is there try

    sudo rmmod -f acer-wmi

    (don't worry this would only be temporary and would return on reboot). Without rebooting retry wireless, if it works we can make it permanent with blacklisting the driver.

    there's no acer_wmi, or this result can be helpful..

    lsmod | grep ath

    Try shutting down(if not already off), disconnecting the power, remove battery(if it is a laptop), press power a few times to release stored energy, reinsert battery(if it is a laptop), reconnect AC power. Turn on computer. Worked for me. After trying multiple fixes I found on the internet I remembered reading this somewhere. My hardware was blocked via a hardware switch(fn+f8 which doesn't work in ubuntu(works with windows, but uninstalled windows). rfkill showed 0: phy0: Wireless Lan as Hard Blocked.
