1. An electronic apparatus, comprising:
a first wired LAN circuit;
a second wired LAN circuit;
a wired LAN management unit configured to switch a wired LAN circuit used for wired LAN communication from one to the other among the first and second wired LAN circuits;
wherein an upperlimit communication speed of the first wired LAN circuit is a predetermined first value, an upperlimit communication speed of the second wired LAN circuit is a predetermined second value, and the second value is smaller than the first value;
power consumption of the second wired LAN circuit is smaller than power consumption of the first wired LAN circuit; and
when the electronic apparatus moves to a suspended status, the wired LAN management unit switches a wired LAN circuit used for wired LAN communication from the first wired LAN circuit to the second wired LAN circuit and the wired LAN management unit (a) powers-on the second wired LAN circuit, (b) transmits an address switching notification to a specific host device through a network using the first wired LAN circuit, the address switching notification causing to switch an IP address of the electronic apparatus from an IP address of the first wired LAN circuit to an IP address of the second wired LAN circuit, and (c) powers-off the first wired LAN circuit.
