Preventing connections to unauthorized access points with channel switch announcements

Abstract:

An unauthorized access point is identified during a periodic scan on the wireless network and storing a MAC address for the unauthorized access point and monitored for connection attempts. In response to an attempt by the unauthorized access point to connect to a wireless station or in response to the wireless station attempt to connect to the unauthorized access point, a spoofed probe response is transmitted to prevent a connection. The probe response can include a channel switching element and the MAC address of the unauthorized access point.
