The PowerLine USB Adapter lets you turn the existing powerlines in your home or office into a high-speed network. Now you don't 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 USB Adapter interfaces USB-equipped PCs to the HomePlug PowerLine network standard. Just plug the PowerLine USB Adapter into the wall, connect your computer to it using the included USB cable, and you've 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 USB Adapters, or Linksys PowerLine EtherFast 10/100 Bridges.
