US Patent 7747219 Method of setting wireless communication device

A relay station 200 constructs an infrastructure wireless network 200L. A printing device 100 requests new participation in the wireless network 200L. When preset conditions are satisfied, for example, when the user has pressed a push button 201 provided on the relay station 200, the relay station 200 establishes temporary wireless communication with the printing device 100 and changes an SSID of the printing device 100 to an SSID of the relay station 200. In this manner, this arrangement readily changes the configuration information of the printing device 100.
