    I OWE YOU A BEER TOO!!

    Sniffing around the net today many people are having this issue. Seems like a bit of a nightmare impacting Dell / Lenovo / Macbook and all the other Broadcom laptops.

    Thanks

    Thank you very, very much Chili555. I spent 2 days trying to explain to myself what happened with the wireless card in my HP ProBook 6360b and finally reached your post which solved this damned problem
    Thanks a lot again.

    Hello all,

    It doesn't work for me. After I install linux-header-generic , then "sudo apt-get install --reinstall bcmwl-kernel-source" . I still get error :

    - No original module exists within this kernel
    - Installation
    - Installing to /lib/modules/3.5.0-27-generic/updates/dkms/


    depmod....

    Do you have linux-backports-modules-cw installed?
    Code:
    sudo dpkg -s linux-backports-modules-cw-3.6-quantal-generic
    If it is installed, remove it and try again:
    Code:
    sudo apt-get remove --purge linux-backports-modules-cw-3.6-quantal-generic
    sudo apt-get remove --purge linux-backports-modules-cw-3.6-`uname -r`
    Those tickmarks are on the left side of my US keyboard on the same key with ~.
    Code:
    sudo apt-get install --reinstall bcmwl-kernel-source
    sudo modprobe wl

    Ideally, if the kernel source were not installed, apt would...do what?...install it! Let's help it along:
    Code:
    sudo apt-get install linux-headers-generic
    sudo apt-get install --reinstall bcmwl-kernel-source
    sudo modprobe wl
    iwconfig
    Now do we have wireless?

    Excelente! Me anduvo a la perfección! Gracias!!

    sudo apt-get install linux-headers-generic
    sudo apt-get install --reinstall bcmwl-kernel-source
    Re-installing following these guidelines helped me out as well after experiencing a similar problem after upgrading to UBUNTO 13.04.

    Cheers!
