You should have one cable coming into your house right now that connects to a cable modem already, then a cord that goes to your main computer from that modem. Take out the cord that goes to your main computer and instead plug it into the router (different from cable modem) and out it into the WAP/Uplink plug in. The router will have about four (or more) extra plugs on the back of it. In one plug you will run a cord back to your main computer, and in another you will run a cord up to your computer on the third floor. It isn't that hard really.
