1. A non-transitory computer-readable recording medium storing computer-readable instructions for a terminal device,
wherein the computer-readable instructions, when executed by a processor of the terminal device, cause the terminal device to:
receive support information from a communication device by using a first wireless connection which has been established between the terminal device and the communication device, the support information indicating whether the communication device supports a predetermined scheme of a Wi-Fi standard;
in a case where the support information indicates that the communication device supports the predetermined scheme and a wireless connection between the terminal device and an external device different from the terminal device has been established, execute a first control process for executing wireless communication in conformity with the predetermined scheme between the terminal device and the communication device,
wherein the wireless communication in conformity with the predetermined scheme further comprises:
sending an authentication request in which a public key of the communication device is used to the communication device;
in a case where the authentication request is sent to the communication device, receiving an authentication response from the communication device; and
after the authentication response has been received from the communication device, sending first connection information to the communication device, the first connection information being information used by the communication device for establishing a second wireless connection in conformity with the predetermined scheme between the communication device and the external device; and
in a case where the support information indicates that the communication device does not support the predetermined scheme or the wireless connection between the terminal device and the external device has not been established, execute a second control process for executing wireless communication in conformity with a different scheme of the Wi-Fi standard different from the predetermined scheme between the terminal device and the communication device,
wherein the wireless communication in conformity with the different scheme comprises:
sending second connection information to the communication device by using the first wireless connection without sending the authentication request to the communication device, the second connection information being information used by the communication device for establishing a third wireless connection in conformity with the different scheme between the communication device and the external device.
