    Hi, try this:
    Code:
    sudo rmmod -f dell_wmi
    if that does not work run this command:
    Code:
    sudo apt-get install --reinstall b43-fwcutter firmware-b43-installer
    watch for errors then run:

    Also set your wireless speed in your router to b/g and see if that helps.
    Code:
    sudo modprobe b43
    Thanks
