Abstract: A wireless network probe method intercepts a data packet sent from a certain station, which has established communication with an access point (AP) connected to a wireless network before a service set identifier (SSID) of the wireless network has been closed. The method further amends data in the data packet to generate two attacked data packets, transmits the two attacked data packets using a media control access (MAC) address of the certain station, to interrupt the communication between the AP and the certain station. Furthermore, the method intercepts a re-association data packet sent to the AP from the certain station, retrieves the SSID from the re-association data packet, and stores the SSID into a second station, so as to connect the second station to the wireless network.
