Abstract: A wireless communication circuit includes a receiver to receive at least one of a beacon frame and a probe response frame from a first wireless communication apparatus belonging to a first communication group, at least one of the beacon frame and the probe response frame including first security information indicating a first encryption method. The circuit includes a transmitter to transmit an association request frame to the first wireless communication apparatus, the association request frame including second security information indicating a second encryption method which is supported by the wireless communication circuit, after a determination that the second encryption method overlaps with the first encryption method. The transmitter declines to associate with the first wireless communication apparatus if the first encryption method fails to overlap with the second encryption method. The transmitter transmits a data frame including a frame body after a reception of an association response frame.
