ABSTRACT:
A communication apparatus, which has a normal power consumption mode and a power saving mode lower in power consumption than in the normal power consumption mode and which is connected to a network via a network interface device, communicates with a device on the network via the network interface device. The communication apparatus acquires capability information indicating a communication capability of the device, and based on acquired capability information, determines a communication mode to be used when the network interface device communicates with the device under a condition that the communication apparatus has shifted to the power saving mode, and when the communication apparatus shifts from the normal power consumption mode to the power saving mode, sets the determined communication mode as a communication mode to be used when the network interface device communicates with the external device.
