I'm relatively new to linux and ubuntu, but I've heard it's a good starting point so I decided to get it running. I have a fair grasp on setting things up, all the sudo apt-get stuff, and for the most part, it sorted itself out. I had it connected to an ethernet cable during install to get updates before I got it started, and when I unplugged it, it connected fine to the wifi at home, but when I attempted to open google through firefox, it failed to work. I was told to do "sudo modprobe lib80211_crypt" and when I entered that, it says "FATAL: Module lib80211_crypt not found". any help is appreciated, thanks.
EDIT: I'm also running 12.04, not 13.04.
