    Wireless on Lenovo b570 not working

    I have a Lenovo b570 laptop and I just installed Ubuntu 12.04.
    I can't get my wireless to work and it's driving me nuts.
    I'm not sure how to fix it.
    I've downloaded the wireless driver, but I'm not sure what to do next.

    Re: Wireless on Lenovo b570 not working

    Several things: The Broadcom-STA driver normally works with this card (from Ubuntu 12.04 the native driver b43 should work, too). But there are several modules loaded, that block each other.

    Open this file:

    Code:
    gksu gedit /etc/modprobe.d/blacklist.conf
    add the following lines:
    Code:
    blacklist bcma
    blacklist brcmsmac
    blacklist brcm80211
    blacklist acer_wmi    #thinkpad!!!
    Save, close the editor, and reboot. Check after that

    Code:
    rfkill list
    iwconfig
    lsmod

    also paste the output of following command


    sudo cat /etc/modprobe.d/blacklist.conf

    Check buttons, switches, keys, and key combinations (e.g. Fn+F2) and/or

    Code:
    rfkill unblock all
    Check the BIOS settings, if it can be activated there, maybe resetting the BIOS to default.

    rfkill unblock all does nothing in terminal and changing BIOS settings didn't do anything either =/

    Lol. I've been trying to fix my computer and my wireless for a week now. Don't insult me XP
    So that's definitely switched on. And I've tried the fn+f5 key that's supposed to turn it on too and neither have turned it on.
    I'm at a frustrated loss and I'm tired of having to connect it to a wired connection):
