Abstract
Wireless devices (clients) 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 client should be steered away from a current AP. Steering may be conducted utilizing BSS transition management (BTM) messages to provide the client with a list of network-preferred APs for a transition. Clients may also have one or more preferred APs and may reject the BTM steering message if it does not include at least one client-preferred AP. To prevent rejection of the BTM message, at least one client-preferred AP may be added to the BTM message. To ensure the client is steered to a network-preferred AP, the client is blacklisted from connecting to the client-preferred AP until the client has been steered to a network-preferred AP.
