1. A method for wireless communication comprising:
setting a current operating channel of a primary radio to a dynamic frequency selection (DFS) channel;
scanning a plurality of available channels using a secondary radio;
determining a channel score for each of the available channels; and
while operating the primary radio on the DFS channel:
determining a candidate DFS backup channel for the primary radio based on the channel scores and further based on an initial vetting of the candidate DFS backup channel using a first set of vetting parameters;
detecting a primary radio event on the current operating channel of the primary radio; and
responsive to detecting the primary radio event and based on continued vetting of the candidate DFS backup channel using a second set of vetting parameters, switching the current operating channel of the primary radio from the DFS channel to the candidate DFS backup channel.
