I've had/have several tickets open for this issue for a long time.
The only reason I post here is to see whether anyone else run into the same issue or whether that is only related to my country setting of Austria.
It happens only with AP36xx and you'd see it in the "active wireless APs" report on radio1...
And the AP log show...
The only fix to it is to reset the AP and then a channel is selected and the AP will provide service again in the 5GHz band.
So I'd appreciate if you'd check your AP36xx installations and let me know if you see the same problem - if yes please provide...
- controller typ and version
In case you want to reference to my ticket the # is 01235020.
