Abstract: A communication device (e.g., a printer) may establish a wireless connection in accordance with a device provisioning protocol (DPP) between the communication device and an external device (e.g., access point) in a state in which a wireless connection has already been established between the communication device and another external device (e.g., access point). The communication device may disconnect its wireless interface from a first external device prior to connecting to a second external device.
