Claim:
1. A computer-implemented method in a controller for automatically selecting Wi-Fi channels for a plurality access points on a data communication network, the method comprising the steps of: managing, with a processor of the controller, the plurality of access points utilizing a set of non-interfering channels on the data communication network, wherein a lack of interference exists between the set of non-interfering channels; receiving scan results from each of the plurality of access points, with a network interface of the controller, the scan results comprising a list of neighboring access points from the plurality of access points relative to each access point; responsive to a number of the plurality of access points exceeding a number of non-interfering channels, assigning, with a processor of the controller, each of the plurality of access points to a non-interfering channel with sharing of at least one of the non-interfering channels, using a GCA (Graph Coloring Algorithm) in which each color assignment corresponds to a non-interfering channel assignment in order to prevent neighboring access points from sharing a non-interfering channel; and sending, with the network interface, the channel assignments to the plurality access point.
