A power extension apparatus for local area networking is disclosed. The power extension apparatus has an array of power sockets and network interface ports on an extension cable, where the power sockets are to connect two or more computing devices to a power line wiring, and the network interface ports are to establish data communications among the computing devices being connected to form a local area network. The local area network can be further linked to other networks also being connected to the power line wiring, which may be in the same building, so long as the data communication is compliant with HomePlug and other similar standards. These computing devices being connected through the power line wiring are able to exchange audio, video, text, and control data bi-directionally.
