They generally flip a shit about anything beyond the basics. I haven't been able to get a Cr-48 to even see the wireless around here. Apparently, the guy who set up the network hates Ubuntu and did his best to make it a pain to connect. Not good IT people.
How I think it works:
You have to register the computer with them to get on the network at all. So when I was using wireless on my laptop and trying to get a wired connection for my desktop going, I got a screen saying that I can only register 1 computer at a time.
Would a router be able to get around that sort of thing? I am not too great with networks, but it seems like it would run into a problem of having another machine on the network.
