The present invention relates to a communications device capable of activating the power saving mode of EEE when it is not activated. The communications device can operate in an auto-negotiation mode. When the CPU of the communications device determines the power saving mode, which is implemented in the auto-negotiation mode, is activated, the CPU controls other device to be configured in the auto-negotiation mode, if the other device is configured in a fixed mode at the other end of communication.
