PROBLEM TO BE SOLVED: To provide a method for stably transmitting a packet having an optimum speed, adapted to a multi-channel environment between nodes in a power line communication system. SOLUTION: The method for transmitting an adaptive multi-channel packet in power line communication system comprises the steps of: (a) transmitting a packet, from a first node to a second node with a predetermined transmission speed through a power line; (b) searching an error of the packet transmitted from the step (a) in the second node, thereafter loading the check result to the packet and transmitting it to the first node through the power line by using a multi-channel; (c) retrieving the result of the packet transmitted from the step (b) in the first node, and storing the check result as a database; (d) transmitting the packet to the second node with one from among the current, downgraded or upgraded transmission speeds, according to the packet transmission success/failure information stored as the database in the step (c); and (e) transmitting the packet with a stable transmission speed according to the multi-channel by performing repeatedly the steps (b) to (d).
