The Ethernet converter includes a LAN switch, an RF device and an antenna, a wired device monitoring module, and an RF device controller. The RF device and the antenna carry out communication with wireless network devices. The wired device monitoring module monitors the operation state of the wired network devices via the LAN switch. The RF device controller controls the operation of the RF device on the basis of the operating state of the wired network devices. If the result of monitoring is that the wired network devices are not operating, the RF device controller stops the operation of the RF device so that power consumption by the RF device is less than when the wired network devices are operating.
