Communication apparatus operable in auto-negotiation mode, method of controlling the communication apparatus, and storage medium

摘要

A communication apparatus capable of activating an EEE power saving mode when not activated. The communication apparatus is operable in an auto-negotiation mode. When a CPU of the communication apparatus determines that a power saving mode to be realized in the auto-negotiation mode is to be activated, if an other-party apparatus at the other end of communication has been set to a fixed mode, the CPU causes the other-party apparatus to be set to the auto-negotiation mode.
