I’ve been struggling for months trying to get my wireless card working in Linux, including installing several different versions of Ubuntu, Mint, and others. I also thought it might be a hardware issue, since some of the newer Debian-based flavors weren’t working with live CDs. I replaced the power supply as well, since the old one was making a horrible sound and the system seemed flaky.
This morning, I stepped into my office at home to grab something, and my computer was sitting at the login prompt for Kubuntu instead of my Windows desktop (meaning, Windows updated itself and rebooted the pc). I decided on a whim to give trying to set up the wireless one more shot.
I didn’t have the network info handy, but looking in /etc/network, I found a backup copy of the interfaces file from when I had messed with it previously, and copied it into place. Restarting networking produced a slew of errors, most of which were from the wired interfaces not being plugged in. Seeing this, I commented those interfaces out of the file, and then I noticed that one line was missing from the wireless interface section that was in all the others, so I added it. I saved the file and restarted networking again, and POOF. Network connectivity! Unpossible!
Sadly though, I did not have much time today to play with my newly-connected desktop as we were busy getting ready to drive over to GR for our mini-vacation, and to see the Jeff Dunham show on Sunday night at the DeVos performance hall.
