If they are all on the same controller, why does rebooting affect the others? Isn't the controller suppose to managing that?
The point of auto is to have the AP detect what channels are in use around it and pick the best one. That will obviously be different each time any AP reboots. When the first one reboots, it will immediately affect the ones next to it as the signal drops and the unit around it detect a difference. Then once it powers back on, it has to detect what is around it and then determine what channel to use.
High density deployments are much different beasts than an office building with 3 or 4 AP scattered around for coverage.
