If the detected temperature T is not smaller than a threshold value Th2 additionally, supply of power to the CPU of the router device is subsequently interrupted. In this way, in a router device powered by a secondary battery, diminished functionality of the secondary battery due to elevated temperature may be prevented.

Abstract: The router device is able to use either battery power or a commercial power supply, and when using battery power detects battery voltage and indicates the level of battery voltage with an LED. When the router device is using battery power, writing of the firmware is disabled. Further, writing of settings information write is disabled when battery voltage goes below a second threshold value; and supply of power to the CPU is subsequently interrupted when battery voltage goes below a first threshold value. In this way the router device of the invention avoids problems occurring due to a drop in battery voltage when using battery power.

Abstract: The invention intends to achieve new additions of terminals that use a wireless LAN with a simple process, while preventing leakage of data indicating cipher keys. The access point is notified of the cipher systems adaptable to the terminals. The access point narrows the cipher systems adaptable to itself, sets the cipher keys and notifies them, and also determines the station IDs for the cipher keys each. Thereafter, when the access point modifies the cipher systems based on the security policy, the access point adopts the station IDs corresponding to the cipher systems each. Therefore, the terminals specify the cipher systems based on the station IDs, and perform wireless communications by using the cipher keys notified in advance.
