@timdj This suggestion was already made in the past too.  So far no change.

My work around has been to generate a daily email at 0800.  If it switched channels in the last 24 hours I'll see it and change it back.  It's a nuisance to say the least.

  @timdj Lately lots of dfs events.  Mine never recovers, even after a few days. So I wrote the script below to perform a dfs channel recovery automatically. As my EAP is not controller managed, the script performs the equivalent of clicking save on the 5G wifi tab. Which is enough to restore the original channel.

This is run as a cron job every 30 minutes on a server that's on all the time. Commands are very simple, using curl to communicate with the AP.

I see from one of your earlier posts you're using the controller. It's my understanding there's API support for the controller, so something similar can be implemented. It took me an evening to hunt down the right url, extract credentials, then figure out the variable expansion in the scripting (for a cleaner script).

Finally had some dfs events.  Things worked as expected.
