That is, since the AP cannot know whether the STA supports WPA3, it cannot recognize whether communication with the STA can be executed if the frequency band is changed to the 6 GHz band.
- the communication device 102 is connected to the STA by WPA3, it is determined as No in this step, and the process of S407 is performed.
- the communication device 102 is connected to the STA by the authentication method before WPA2, it determines Yes in this step and displays S405. In this step, when the STA and the OWE system are connected by the Open, the communication device 102 may be determined to be Yes.

- the communication device 102 determines whether the already set authentication information can be used as a communication parameter in the 6 GHz band (S408). Specifically, for example, it is determined whether the pre-shared key of WPA2 can be used as the password of WPA3. When the use of the pre-shared key as a password is permitted, the communication device 102 determines Yes in this step and performs the process of S409. On the other hand, if the use of the pre-shared key as a password is not permitted, the communication device 102 determines No in this step and performs the process of S410. Whether or not the pre-shared key of WPA and WPA2 may be used as the password of WPA3 is set in the communication device 102 by the user.
- the communication device 102 determines this step based on whether or not the number of characters in the character string set as the pre-shared key of WPA and WPA2 is equal to or greater than the predetermined number of characters required as the password of WPA3. May be good. The communication device 102 determines Yes in this step when the number of characters of the pre-shared key is equal to or greater than the predetermined number of characters, and determines No in this step when the number of characters is less than the predetermined number of characters.
- the already set authentication method is set as a communication parameter in 6 GHz band communication (S409).
- the pre-shared key of WPA and WPA2 is set as the password of WPA3.
- the pre-shared keys of WPA and WPA2 may be automatically entered in the WPA3 password input field on the setting screen. Even when the process of S409 is performed, the user may accept the change of the password.
