What else could it be?!

Hi I'm a new member but I've been a limewire user for a long time. My specs are Windows XP, Norton Antivirus 2006, Latest spysweeper. Toshiba laptop, windows firewall is OFF. My problem is downloading and searching I guess. When I was at home I used a wireless LAN on this same machine and limewire was perfect!! My downloads never took more than 3 min a piece and it connected fast. I'm now at college at an apartment complex using a wired LAN. My roomate has a desktop and he is downloading just fine. He has the same specs as far a OS but a little different virus software. Someone please give me some ideas of what it may be I'm going crazy not being able to download. Limewire connects but it's very slow. I will have all green bars but when I download something the connection starts dropping and they take 2-3 hours. It's got to be something small that I'm just overlooking. Thanks for any help guys.
