Abstract: A terminal of a communication system may obtain location information of a server of the communication system and related information related to a public key of a communication device of the communication system by using a computer program. The terminal may send a web page request to the server by using a browser program, receive web page data from the server by using the browser program, display as web page by using the browser program and activate the connection application by using the browser program. The terminal may obtain the public key by using the connection application, send an authentication request to the communication device by using the connection application, receive an authentication response from the communication device by using the connection application and execute a target communication with the communication device by using the connection application.

Abstract: A terminal device may determine whether the terminal device has been established a wireless connection with an access point. In a case where it is determined that the terminal device has been established the wireless connection with the access point, the terminal device may send first connection information to the communication device, the first connection information being for establishing a wireless connection between the communication device and the access point. In a case where it is determined that the terminal device has not been established the wireless connection with the access point, the terminal device may communicate second connection information with the communication device, the second connection information being for establishing a wireless connection between the terminal device and the communication device not via the access point.
