Abstract

A network controller includes a communication portion, a disconnection portion, a change portion, and a re-linking portion. The communication portion is capable of communicating with another network device via a network. The disconnection portion temporarily disconnects communication from the communication portion to the other network device when a sleep signal instructing a shift from a normal state to a sleep state is received. The change portion changes a speed of the disconnected communication from the communication portion to the other network device, to a communication speed lower than a communication speed in the normal state. The re-linking portion causes the communication portion to communicate with the other network device at the changed communication speed.

First claim

What is claimed is:

1. A network controller that can be shifted from a normal state to a sleep state, comprising:
a communication portion capable of communicating with another network device via a network;
a disconnection portion configured to temporarily disconnect communication from the communication portion to the other network device when a sleep signal instructing a shift from the normal state to the sleep state is received;
a change portion configured to change a communi…
