A media access control (MAC) controller is disclosed for a network providing communication for network stations located at a plurality of customer premises and sharing a communication medium, each of the premises having a plurality of network stations. The MAC controller includes a virtual local area network (vLAN) controller, providing access to the communication medium for and communication among the stations located at a single customer's premises, to define a vLAN between them. A group local area network (gLAN) controller provides access to the communication medium for and communication among interfering vLANs, two vLANs being considered to be interfering when one can sense communications over the medium from a station in the other. A MAC controller is provided in at least one station in a vLAN. The MAC controller is preferably connected to use as the communication medium the portion of a power line at the output of the last step down transformer and utilizes a token passing protocol to control access to the medium.
