    Airport / Wireless / Wifi not working on Intel iMac after last update of 12.10

    Hi Guys

    I am running 12.10 on an intel imac and it was running perfectly fine until the last update. Now suddenly, my airport / wireless networking doesn't work anymore since the update. In the networking menu, I don't even see an option to enable/disable wireless anymore, which leads me to believe the system isn't even detecting the hardware. I would appreciate any help.

    Thanks.

    Ok I managed to solve it. Just need to uninstall bcmwl-kernel-source. Search for it in synaptic package manager and uninstall and REBOOT. The airport and wifi should start working again.

    In case after uninstalling, it still doesn't work, install the firmware manually. Instructions here: http://askubuntu.com/questions/16650...wifi-wont-work
