    Broadcom Headache-No wireless

    I have ubuntu 12.10, and after I installed the updates about two weeks ago the wireless card stopped working. I have a Broadcom 4312 wireless card.
    Code:
    rfkill list
    returns nothing.
    Software Sources says I am using the proprietary driver. I have fwcutter installed.

    Code:
    lshw -C network
    returns:

    I have firmware-b43-lpphy-installer installed

    Should I change that?

    Thanks

    Post back the output of lsmod so we can see which modules are getting loaded at boot.

    Re: Broadcom Headache-No wireless

    Hi, copy and paste this command in the terminal (ctrl+alt+t) please:
    Code:
    wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script
    It will download a script and create a text file in your home folder with wireless information so we can see the condition of your wireless at this time and the Mac address, WPA key and WEP key are removed for your security, then reply back and attach the netinfo.txt file.
    Thanks
