uTorrent does not function, shuts down wireless network

[Dr.Oranges]

I own a Toshiba Satellite laptop running Windows Vista. I recently reformatted my computer and reinstalled Vista; I'm fairly certain I've updated the OS and the drivers up to spec.

My roommates and I are on a small wireless network based off a Belkin F5D7230-4 router. The router uplink connects to a fiberoptic cable which runs through a media converter. We're on a university connection, but last year, when I connected directly w/ the cable, I had no problems with uTorrent. Now, however, whenever I instruct uTorrent to download a fire, not only can it not find any incoming connections, I also cannot browse the internet and receive 404's when I try to access pages. My roommate can browse the internet, but very slowly, and his torrents also cannot find any incoming connections. We set up the wireless network, not the university. Also, in the router's settings, it says that uTorrent's required port is open, but the uTorrent port-forward test claims the port is NOT open.

Belkin routers are horrific. They can only handle a very low number of connections before they crash. Throw it away and buy something better. A WRT54GL will do, just replace the firmware with something like Tomato (trivial to do).
