the wan port is used for, well, the wan. you hook it up to the ethernet port on the cable or dsl box. to attatch a hub you have to connect it to the switch part of the router. the uplink port is best to use because you dont have to use a crossover cable. but when you hook a hub up to the uplink you lose the use of port one.
i went to the tomshardware forums and all i got was this lousy signature.
