Abstract: Dynamic bandwidth selection techniques are provided for a plurality of wireless access point devices that operate in a wireless local area network. Each access point device is capable of serving wireless client devices with a bandwidth from a set of possible bandwidths associated with one or multiple contiguous or non-contiguous radio frequency channels. A bias is generated based on determined type of traffic or client composition for each access point device, the bias favoring a channel assignment that results in a particular bandwidth in the set of bandwidths. The bias is applied to metrics representing severity and degree of interference for each channel to generate adjusted metrics. A bandwidth from the set of possible bandwidths is selected for each access point device based on the adjusted metrics.
