There is an alternative to wi-fi, in practical use, that does not suffer from its disadvantages: dLAN (‘domestic local area networks’). dLAN systems make it possible to use the mains electric circuitry of a building to connect by wire to the internet or to other computers from any room that has an electric socket. It is safer and more secure than wi-fi, faster and more reliable.
