1. A method of operating a wireless network, comprising:
receiving, by a controller including at least first and second access points (APs), a first probe request from a client device at the first AP operating at a first frequency range of the wireless network;
establishing, by the controller, a first association between the first AP and the client device;
sending, by the controller responsive to determining the first association is with the first AP, a transition request using the first AP to instruct the client device to transition to the second AP, wherein the second AP is a default AP, operating at a second frequency range of the wireless network, and having a second bandwidth that is different from a first bandwidth of the first AP; and
establishing, by the controller, a second association between the second AP and the client device.
