    Re: Turn on wifi

    Hi, please install the backport modules and then unplug your wired connection and restart your computer and see if it will connect.
    Code:
    sudo apt-get install linux-backports-modules-wireless-maverick-generic
    If it does not post the results of:
    Code:
    lsmod
    again.
    Thank you
