For example, the communicable range of a wireless LAN device according to the normal IEEE 802.11 standard is a range of several tens of meters, and it is difficult to provide an infrastructure in which a single communication carrier can communicate. As described above, there are many communication carriers (including free ones) that provide wireless LAN communication. Therefore, in the wireless LAN communication, it is necessary to perform an appropriate network setting every time it is used. As the necessary setting work, for example, there is a work of inputting an SSID (Service Set Identifier) and a WEP (Wired Equivalent Privacy) key corresponding to the access point of the wireless LAN to be connected.
