Abstract:
1. A network relay device configured for wired connections to a plurality of first network devices and for wireless connection to a second network device to relay communications between the plurality of first network devices and the second network device with reduced standby power consumption, comprising: a wired communication unit configured to carry out communication with the plurality of first network devices; a wireless communication unit configured to carry out communication with the second network device; a monitoring portion configured to monitor the plurality of first network devices via the wired communication unit and to decide whether an operating state of each of the plurality of first network devices is a communication-enabled state or a communication-disabled state not requiring the relaying of information; and a control portion configured to control an operation of the wireless communication unit, wherein the control portion stops the operation of the wireless communication unit when the operating state of all of the plurality of first network devices is the communication-disabled state and wherein at the startup of the network relay device, when the monitoring portion decides that the operating states of all of the plurality of first network devices are the communication-disabled states, the control portion does not start up the operation of the wireless communication unit, but starts up the operation of one or more components of the network relay device other than the wireless communication unit.
