Communication apparatus, control method, and computer-readable storage medium

A non-transitory computer-readable storage medium that stores a program for causing, when the program is executed by a computer included in a communication apparatus capable of executing communication complying with an IEEE 802.11 standard series using a plurality of communication interfaces, the computer to carry out a control method comprising:

• in a case where communication with an access point (AP) using a first communication interface as a station (STA) and communication with another apparatus functioning as a Client (CL) using a second communication interface as a Group Owner (GO) of a Wi-Fi Direct (WFD) standard are concurrently performed, and in a case where a first wireless frame indicating a change of a frequency channel in use is received from the AP during a time when the first communication interface uses a frequency channel in a predetermined frequency band that needs support of a Dynamic Frequency Selection (DFS) function, confirming whether the second communication interface uses the same frequency channel in the predetermined frequency band as that of the first communication interface;
• and
• in a case where it is confirmed that the second communication interface uses the same frequency channel in the predetermined frequency band as that of the first communication interface, changing the frequency channel of the first communication interface and the second communication interface based on the first wireless frame.
