A controlling device may acquire setting information regarding a wireless setting for a wireless communication currently being set in a wireless communication device. The controlling device may determine, using the setting information, whether the wireless setting indicates a first authentication method in which an authentication is performed by an authentication server or a second authentication method in which an authentication is performed by a device with which the wireless communication performing unit performs a wireless communication directly. The controlling device may provide a first screen to a displaying unit in a first case where a determination is made that the wireless setting indicates the first authentication method. The controlling device may provide a second screen which is different from the first screen to the displaying unit in a second case where a determination is made that the wireless setting indicates the second authentication method.
