Sooooo, little help here

I used to split the cable that came into my livingroom to a wireless router, and then the other to the TV. Finally go around to getting in the walls and made some nice adjustments to get a cable going up to my second floor. Since it was going to be going to my Desktop, bedroom and livingroom, I bought a repeater. A 4 way Distributor Amp from GE ( similar to this http://www.biggabuys.com/servlet/the...l-Cable/Detail)

Got it all hooped up, but the internet does not work. If i detach the repeater and use a splitter on the same cables, well I'm here typing this. Ideas? A more computer savy friend (who is now on a honeymoon so I cant/wont contact him) said the repeater was the way to go.

Thanks all and hope to see you in game!
