http://ubuntuforums.org – Hello all, I have googeld and searched the forum for the answer for the better part of the day. I just did a complete wipe of my machine (Dell Inspirion N5010) and installed 12.10. Wifi worked and then I did the update and now wifi is gone. :( Wireless is gone from my network options but the name of the wireless network I used prior to update is still in the Wireless tab of the Network Connections. This is my first experience with Linux. In the terminal, I put in "rfkill list" and it returned nothing at all. Any help is appreciated. (Hardware)
