Ok, I'm having TWC bring a Motorola SB5120, and a Router...How does this work?? Like where is the router left at?? The original computer or what?? and how do you get it hooked up in an other room...In my bedroom all I have is a cable line near the wall?? How do I hook it to my PS2 when I need a ethernet cord for that?? Well can someone just give me an explaination on where things go how its set up?? Thanks
