A wireless LAN access point device is structured to perform frame-based data transmission and reception to and from a wireless terminal over a wireless communication path. The wireless LAN access point device has a communication module configured to transmit and receive a frame to and from the wireless terminal. In the wireless LAN access point device, when the communication module receives a predetermined management frame from the wireless terminal, an execution module performs a corresponding operation specified by the received management frame. In the wireless LAN access point device, when the communication module receives a frame, a sequence monitor module obtains a sequence number included in the frame. In the wireless LAN access point device, when a first sequence number obtained by the sequence monitor module and a second sequence number included in the received management frame satisfy a preset condition, an unauthorized frame judgment module identifies the received management frame as an unauthorized frame. This arrangement has the high versatility and effectively protects a wireless LAN network from unauthorized accesses.
