You might consider getting some very thin (I use white color) long length telephone cord to run into adjacent rooms, etc. I use two of these to connect 3 boxes in the living room (no broadband there, yet) to the phone jack clear across the other side of the room. I think they still sell them at Target.
The thin, white cord runs along the door frame and the baseboard and it blends in perfectly to the room and is mostly out of sight, and no one ever notices it. However, DO NOT run thin telephone cords under carpet as they may easily fray and could cause a fire.
The other solution (one I am working on) is to set-up a wired network, or a wireless network to use the boxes' broadband jack. Good luck, or if you have broadband you could use the Dish Com set-up (accessing your internet connection using your existing wiring in your home by plugging it into the wall outlet. I don't have that, but someone who knows can explain more.
