Hold on take a step back here. Not trying to be blunt but there is a lot wrong here. First off you would not be using a phone jack as an alternative to ethernet through the home. So let me recommend something. It sounds like what you need is something called powerline adapters. These will use your homes own wiring to transmit the data. In your case you may want to grab one with wireless capabilities on the receiving end. They are pretty simple to setup. You use one of the ports on the back of your router for this and find a nearby outlet that you can plug it in to. Then the area where you need to be getting the connection is where you would place the other part of the set. I know netgear makes a decent one here is what i would think would be good for you [ Register or Signin to view external links. ]
