Monnat, if the controller is at the provider side, yes that make sense.
By this way, you can upgrade you AP the the new AP firmware version and take access to the firmware version improves. In this case, the provider will change your AP zone to a 3.2 firmware zone. But if your AP have not support on 3.2, then you can stay in 3.1.1 provider zone, or upgrade the AP to 3.2 and use it on stand alone mode. Make sense?
