I've said it 10000 times : If you capitalize the entire name, it's ok.
Incidentally, the problem was retarted. I was almost positive that the problem was with my router. I spent over an hour trying to fix it, but I got mad and unplugged it, plugging the wireless directly into the Internet. Then it still didn't work!
I eventually, after restarting darkside a couple more times, realized that a default gateway wasn't being set. D'oh!
I'll probably plug the proper router back in tomorrow, so there'll be a little downtime in the evening. Not for long, though.
