The setting device includes a communication device and a processing device. The communication device communicates with the electronic apparatuses. The processing device transmits first configuration information representing a fixed first configuration used to connect one of the electronic apparatuses to a network to the electronic apparatus with the communication device taking detection of the electronic apparatus by the communication device as a trigger, and then makes the electronic apparatus store the first configuration information. Further, the processing device transmits second configuration information representing a fixed second configuration which is different from the first configuration and which is used to connect the other of the electronic apparatuses to the network to the electronic apparatus with the communication device taking detection of the electronic apparatus by the communication device as a trigger, and then makes the electronic apparatus store the second configuration information after transmitting the first configuration information.
