Claim:
1. A method to optimize communications on a channel between an access point and a plurality of client devices, said channel being characterized by a center frequency and a bandwidth, said method comprising: establishing by the access point a connection with the client devices on a first channel having a first center frequency and a first bandwidth; exchanging by the access point data through the first channel with the client devices; monitoring by the access point a first interference level on the first channel; reviewing compatibility levels to the access point from the client devices, a compatibility level for a client device defining whether the client device is able to dynamically switch from the first channel to another second channel having a different center frequency and if the client device will change channels in response to an instruction from the access point; instructing the client devices to switch to a second channel having a different center frequency and/or a different bandwidth only if all compatibility levels for all client devices indicate that all client devices are able to dynamically switch from the first channel to the second channel; determining by the access point a second interference level on the second channel; comparing by the access point the first interference level with the second interference level; and deciding by the access point whether to switch back to the first channel based on the comparison.
