COMMUNICATION ADAPTER, SETTING METHOD OF COMMUNICATION APPARATUS, PROGRAM, AND NETWORK SYSTEM

PROBLEM TO BE SOLVED: To connect household electrical appliance easily with a network, without complicating the configuration of apparatus building the network.SOLUTION: A setting device 40A for storing the setting information 51 required for the communication with a network can be connected, as a household electrical appliance, with a wireless communication adapter 30 connecting an access point of the network and the household electrical appliance. Consequently, the wireless communication adapter 30 can be set up with the setting information by using the setting device 40A. Since the wireless communication adapter 30 does not require an interface for setting up the setting information, the device can be simplified. Furthermore, the information required for communication can be set up easily, by using a personal computer as the setting device 40A.
