Explanation:
If the mesh access point does detect radar, the controller and the mesh access point both will retain the channel as the configured channel. The controller retains it in volatile memory associated with the mesh access point, and the mesh access point has it stored in its flash as configuration. After the 30 minute quiet period, the controller returns the mesh access point to the static value, regardless of whether the mesh access point has been configured with a new channel or not. In order to overcome this, configure the mesh access point with a new channel, and reboot the mesh access point.
