The PowerLine AV Ethernet Adapter lets you turn the existing powerlines in your home or office into a high-speed network. Now you do not have to drill through the walls and climb through the attic or cellar to install network cables -- just use the wires that already run through the building! The PowerLine AV Adapter interfaces Ethernet devices to the HomePlug AV PowerLine network standard. Just plug the PowerLine AV Adapter into the wall, and connect your Ethernet-equipped device to the Adapter using the included network cable, and you have turned your whole house into network infrastructure! Attach more computers to the network by simply plugging them into the wall anywhere in the house, using more PowerLine AV Adapters.
