Actiontec MegaPlug 85 Mbps Ethernet Adapter Twin-Pack

The Actiontec MegaPlug allows you to easily extend the range of your wired network to nearly any location in your home. It does this by routing your network traffic over the electrical power lines inside your walls! Simply plug in one ethernet adapter into any 2- or 3-prong outlet, that is nearby to your router or wireless gateway, then plug the other adapter into another outlet anywhere else in your home. It\'s really that simple, and a whole lot easier than the convential method of running cables all over your house. (Amazon)
