A network communication device has plural different connectors, each connectable to a network, and is capable of automatically selecting between the different connectors for network communication. A selector responsive to a selection signal selects one of the plural connectors, and a plurality of detectors, each associated with a corresponding connector, detects whether its corresponding connector is connected to the network. A processor executes a selection process by outputting a selection signal so as to select, in turn, each of the plural different connectors starting with a first connector, maintaining the state of the selection signal in a case where the detector associated with the selected connector indicates connection to the network, cycling to the next connector in a case where the detector does not indicate connection to the network, and repeating the selection process in a case where said processor has cycled through all of said plural connectors.
