Abstract
A spoofed management frame is sent to an unauthorized access point (AP) on behalf of a station from an authorized AP, using a media access control (MAC) address of the station. The spoofed frame triggers a security association (SA) query from an unauthorized AP to reestablish valid communications. An acknowledgment (ACK) frame sent from the client to the unauthorized AP responsive to the SA query request is detected by the AP. A probe response is sent to the client. The probe response includes a channel switching element. The channel switching prevents the client from completing the SA process before a time out.
