http://askubuntu.com – I just upgraded from a older version of Ubuntu and upgraded to 12.04. I had my wireless working on the older version and seem to be having issues now. My ethernet connection works, but it seems that the wireless is not "on". If I select edit connections I can see all my old wireless connections, but there is no "connect to" option anywhere. I've followed this guide Wireless not working on Dell XPS 17 after installing 12.04 with the following result. I am pretty sure I need this module... Not sure what my next steps should be. kevin@MrCoomputerU:~/Desktop$ sudo modprobe iwlagn FATAL: Mo (HowTos)
