A method ( 10, 40, 50 or 55 ) or system ( 200 ) of detecting and avoiding periodic intermittent interference (PII) can include monitoring ( 12 ) for PII on a current channel which can include monitoring ( 14 ) by tracking retransmission statistics of isochronous traffic or by tracking channel probe request failures corresponding to temporal characteristics of microwave oven interference where PII is detected if the retransmission statistics exceed a predetermined threshold or if the probe failure requests exceed another predetermined threshold. The method can further include selecting ( 16 ) a channel or an adjacent channel with a highest level of PII when PII is detected on the current channel which can optionally include selecting ( 18 ) a preset channel known for PII interference or adaptively selecting by directly measuring energy levels on a plurality of channels. The method can switch ( 20 ) to a preferred channel when PII is no longer detected on the current channel.
