OK Im in my college dorm room, and when I use my wireless router (even when Im hard wired into it) Limwire ceases to work, however when I connect straight to the wall it does work....so Im trying to figure out whats going on....is there a way that I was supposed to configure my router so that everything should work?

The only thing that I have done with the router is encrypt it, and it is a D-Link DI-524, and its been working fine til now....
