Abstract:
A communication apparatus transmits an authentication frame to an authentication apparatus and receives a response frame for response to the authentication frame from the authentication apparatus so that an authentication process is performed for the communication apparatus by the authentication apparatus. In the communication apparatus, a transmitting section transmits an authentication frame to the authentication apparatus using a multicast address as a transmission destination address, and if a reception determining section determines that the response frame is not received from the authentication apparatus, a transmission destination address changing section changes the transmission destination address from the multicast address to a broadcast address, and the transmitting section transmits the authentication frame that has the transmission destination address changed to the broadcast address to the authentication apparatus.
