A wireless local area network access point (WAP) includes a transceiver, a controller, and a security unit. The transceiver communicates messages with an end-point communication device through a wireless air interface in a defined frequency band. The controller receives through the transceiver a connection request message containing a password from the end-point communication device, authenticates the received password, and responds to the authentication by transmitting through the transceiver to the end-point communication device an encryption key as a connection response message. The security unit generates a security alert based on measured characteristics of one or more received connection request messages and/or based on measured characteristics of interfering signals in the defined frequency band.
