[ubuntu] Wifi card not working in ubuntu 12.04

view story

http://ubuntuforums.org – Hello, I have installed ubuntu 12.04 in my laptop. It has an Intel 5100 wifi link and the wireless is not working! I have googled and tried the: - edit the /etc/modprobe.d/disable.conf trick - replaced the firmware for the driver Is there any idea of what to do next? Is this problem fixed in a newer version of the kernel? If so, which one? Could you please advise? This bug is UNTHINKABLE and UNACCEPTABLE in a LTS version of Ubuntu.... :( Cheers, Cat (Hardware)
