A network topology and packet routing method for implementing a Local Area Network (LAN) using low-voltage (120/240VAC) power wiring as the transport medium. An Access Point (AP) having a Power Line Carrier (PLC) interface and one or more IEEE 802.3 Ethernet interfaces connects to the logical center of the Power Line medium via its PLC interface. Multiple User Terminals (UT) send to and receive from their associated AP, which in turn routes data packets toward the appropriate destination. Large networks may contain more than one AP, in which case each UT selects its AP based on a metric representing connection quality between the UT and the AP.
