A wireless communication system includes a wireless host and a wireless device. The wireless device includes a user authentication unit that authenticates a requesting user that is using the wireless host based on a result of comparison between a requesting-user ID of the requesting user received from the host and a user ID of a user that is permitted to establish communication with the wireless device. When the requesting user is authenticated by the user authentication unit, information required prior to connection is stored in the wireless device and the wireless host. The wireless device permits to continue the association process with the wireless host, when the information required prior to connection received from the wireless host and the information required prior to connection stored in the wireless device match.
