Communication apparatus, control method therefor, and storage medium

A method for controlling a communication apparatus having a first power consumption mode and a second power consumption mode lower in power consumption than in the first power consumption mode, the method comprising:

• communicating with a device on a network connected via a network interface device;
• acquiring, from the network interface device, capability information indicating a communication capability of the device;
• determining, based on the acquired capability information, 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 second power consumption mode;
• and
• setting, when the communication apparatus shifts from the first power consumption mode to the second power consumption mode, the determined communication mode as a communication mode to be used when the network interface device communicates with the device.

A non-transitory computer-readable storage medium storing a program for causing a computer to execute a process, the process comprising:

• communicating with a device on a network connected via a network interface device;
• acquiring, from the network interface device, capability information indicating a communication capability of the device;
• determining a communication mode to be used when the network interface device communicates with the external device under a condition that the communication apparatus has shifted to the second power consumption mode lower in power consumption than in a first power consumption mode based on the acquired capability information;
• and
• setting the determined communication mode as a communication mode to be used when the network interface device communicates with the device when the communication apparatus shifts from the first power consumption mode to the second power consumption mode.
