Abstract
Wireless devices connect to different access points (AP) in a wireless network. The wireless network may determine that based on, for example, congestion of certain APs that a wireless device should be steered away from a current AP. The steering may be conducted utilizing blacklist steering where one or more APs blacklist the wireless device from being connected thereto. Alternatively, BSS transition management (BTM) steering may be utilized to provide the wireless device with a list of one or more network-preferred APs it should transition to. BTM steering is preferable but not all wireless devices support it so blacklist steering is utilized unless it is known that the wireless device supports BTM steering. Wireless devices do not always indicate they support BTM steering in same manner. BTM steering primer messages are utilized when a wireless device is in line for steering to determine whether BTM steering is supported.
