When we bought our house 7 or so years ago, my buddy (who works in IT), talked me into gutting the phone and cable system prior to moving in (as part of many other renovations).
We ran all new phone wire, and wired the house for both CATV and SAT... The Satelite having home runs back to the 'panel' for each jack. The sat wires are the ones hanging there with terminated ends, but not hooked up. We then ran CAT5 to each room (1-4 jacks to each room) for network. It worked out fantastically, as a year later, UVERSE rolled into town, and our house was pre-wired.
Excuse the mess, as a couple wires need to buttoned up, as the gateway was recently replaced, and needs to be reattached to the wall. Also, sorry for the blurry shot.
