Abstract: When connecting a wireless LAN terminal to a specific wireless access point, an inquiry is made to a server about the specific wireless access point, via the wireless access point which the wireless LAN terminal is connecting to, and then connection information for connecting to the specific wireless access point is automatically received, whereby wireless communication are established between the wireless LAN terminal and the specific wireless access point. Furthermore, in a case where wireless LAN terminals which are permitted to connect are registered into each wireless access point, when a wireless access point receives a connection request from a wireless LAN terminal that is not permitted to connect, an inquiry is made to another wireless access point regarding whether there is a wireless access point which that wireless LAN terminal is permitted to connect to.
