As a learning experiment, I'm trying to turn Ubuntu Desktop into a server. I was able to disable X at boot time and now, I am trying to get my computer to connect to my WiFi network at boot time, before any user logs in. That way, I won't have to be physically near my computer every time it reboots. I've set up the WiFi connection using the Network Manager if that can help somehow (would be nice not having to reconfigure it again!).
