A non-transitory computer-readable data storage medium having a computer program recorded, said computer program controlling a computer, when installed and run, to function as a wireless communicator comprising:

• a plurality of network processors transmitting data to and receiving data from respective different networks;
• a media access control (MAC) setter receiving pieces of information on a MAC layer from the plurality of network processors and storing the pieces of information on the MAC layer;
• and
• a MAC processor performing operations on media access control on a basis of the pieces of information stored in the MAC setter,
• said computer program further controlling said computer functioning as the wireless communicator so that a frame signal containing network identification information corresponding to the respective network processors is supplied from the plurality of network processors to the MAC processor.
