Thanks guys. I'll see what I can find out tomorrow.

My suspicion is that some kid wanted to get wireless in their room, but didn't have a clue how to do it and ended up connecting the WAN port to the wall jack in his bedroom. Ugh.

Sadly, I do NOT have managed switches. This is, after all, an organization that in the past has told me to get the least expensive thing that'll get the job done. It's a wonder I was able to spring for the L in the WRT54GL Nevermind that the poor little router has to support over 130 college kids. I'm amazed it hasn't exploded yet. It's sitting right next to another one (and a couple cheap switches) on a wooden ledge in a tiny closet with no ventilation.
