A system and method are disclosed that may allow a STA to selectively change frequency bands from an operating band to a candidate band based on operating conditions. In response to determining that a channel condition is within a band switch region associated with a candidate band, the STA may select the candidate band and temporarily switch to it. The STA may select an initial modulation and coding scheme for the candidate band and probe the candidate band with data to determine an estimate of candidate band goodput. If the estimate of candidate band goodput is greater than the operating band goodput, the STA may switch to the candidate band.
