1. A router device comprising:
- a battery connection portion adapted to connect to a battery and to receive supply of power from the connected battery to the router device;
a detecting portion adapted to detect output voltage of the battery;
an indicator portion adapted to indicate the level of detected output voltage; and
a power interrupt portion adapted to interrupt subsequent power supply from the battery when the detected output voltage has fallen below a first threshold value.

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.

10. A router device comprising:
-
a power supply portion using battery and adapted to supply the router device with power for operation; a storage portion in which normal firmware subject to updating and backup firmware not subject to updating are stored so as to be independently runnable at startup of the router device; an update portion adapted to perform updating of the normal firmware; a decision portion adapted to decide at startup whether the normal firmware is runnable; and a run portion that run the backup firmware instead of the normal firmware according to the decision of the decision portion.
