  1. I'd rather comment but can't sorry!

    which version of Ubuntu are you using? I encountered the same problem when I upgraded to Natty on my Lenovo Ideapad, also Broadcom 4313. You could try the solutions here: http://ubuntuforums.org/showthread.php?t=1700897

    Ultimately I downgraded because nothing worked for me & everything is fine now. I'll wait for the next LTS. Hopefully you'll find a solution! I shifted my home to a separate partition so that I can do fresh installs without erasing my documents.

  2. For my Lenovo U160 I blacklisted the acer_wmi module and afterwards the wireless worked perfectly. Maybe that solves it for you as well.

    in

    /etc/modprobe.d/blacklist.conf

    add

    blacklist acer_wmi

    It realy works! /etc/modprobe.d/blacklist.conf add blacklist acer_wmi

    to do this write sudo vi /etc/modprobe.d/blacklist.conf

    then enter the password

    go to a clean line and pres the insert key, this will enable input mode in vi

    write

    blacklist acer_wmi

    then pres esc key several times.

    then write :wq! then pres enter

    (for sayfty back up the file first, once the acer_wmi is blacklisted reboot )

    reboot
