My belkin router keeps losing connection, any ideas what could be causing this?

I'd look at any built in logs. Does the router have a web based setup with some sort of logging? Did you look at your computers event viewer and use task manager and did you set up a performace monitor? Try that all and report back on new thread.

what am i looking for though?

Over heating will do this also.

Today seems like a good day to chew through the restraints.
