dont listen to any of these dolts
you dont NEED a router, and all that crap. its nicer that way though.
you can just plug your broadband modem (dsl/cable) directly into your ps2's adaptor. you only need to put it into a hub and etc, if you want your computer to be on the hub to to share internet with your ps2. if you only want to use the ps2 by itself online, then just plug the sum***** in there.
