A device which is capable of minimizing the use of resources in devices and safely communicating information such as settings on devices. The device is capable of communicating with another device via a wireless communication network and manages the other device. The device leaves a first wireless communication network to which the device is currently connected. Then, the device wirelessly connects to the other device so as to construct, with the other device that left the first wireless communication network after the device, a second wireless communication network, which is different from the first wireless communication network, by using a setting network ID for use in a setting change mode for changing setting values of the other device. The device sends setting data to the other device, to which the device was wirelessly connected, via the second wireless communication network.
