Communication apparatus

A method of controlling a communication apparatus capable of performing first wireless communication through an external access point and second wireless communication without an external access point, the method comprising:

• receiving, after a wireless setting mode is enabled, information about an external access point outside the communication apparatus from a terminal apparatus through direct connection established with the terminal apparatus without the external access point;
• performing, in a state where the communication apparatus is connected to the external access point based on the received information about the external access point and the communication apparatus is capable of acquiring frequency information usable in wireless communication of a 6 GHz band from an external system, control to display a first setting screen in which the 6 GHz band is settable as a frequency band to be used when the communication apparatus operates as a master station in the second wireless communication;
• performing, in a state where the communication apparatus is not capable of acquiring the frequency information usable in the wireless communication of the 6 GHz band from the external system, control to display a second setting screen in which the 6 GHz band is not settable as the frequency band to be used when the communication apparatus operates as the master station in the second wireless communication;
• specifying, after the 6 GHz band is set in the first setting screen, a communication channel of the 6 GHz band based on the frequency information received from the external system;
• and
• controlling the communication apparatus to operate as the master station in the second wireless communication by using the specified channel.

A non-transitory computer-readable storage medium storing one or more programs configured to cause one or more computers to function as:

• a reception unit configured to receive, in a case where a wireless setting mode is enabled, information about an external access point outside the communication apparatus from a terminal apparatus through direct connection established with the terminal apparatus without the external access point;
• a first display control unit configured to perform, in a state where the communication apparatus is connected to the external access point based on the information about the external access point received by the reception unit and the communication apparatus is capable of acquiring frequency information usable in wireless communication of a 6 GHz band from an external system, control to display a first setting screen in which the 6 GHz band is settable as a frequency band to be used when the communication apparatus operates as a master station in the second wireless communication;
• a second display control unit configured to perform, in a state where the communication apparatus is not capable of acquiring the frequency information usable in the wireless communication of the 6 GHz band from the external system, control to display a second setting screen in which the 6 GHz band is not settable as the frequency band to be used when the communication apparatus operates as the master station in the second wireless communication;
• a specification unit configured to specify, in a case where the 6 GHz band is set in the first setting screen, a communication channel of the 6 GHz band based on the frequency information received from the external system;
• and
• a wireless communication control unit configured to control the communication apparatus to operate as the master station in the second wireless communication by using the specified channel.
