A communication device may shift an operation state of the communication device from a child station state to a specific state, in a case where a first wireless connection with a second external device is established via a second wireless interface under a predetermined state where the communication device is participating, as a child station, in a first wireless network in which a first external device is a parent station. The communication device may receive a request signal from the second external device via a first wireless interface after the operation state has been shifted to the specific state, and in a case where the request signal is received from the second external device, establish a second wireless connection with the second external device via the first wireless interface so as to belong to a second wireless network for executing a wireless communication via the first wireless interface.
