Wired Networks Wired networks connect personal computers, laptops, printers and modems with cable, including phone line, power line or Ethernet links.
Ethernet requires special wires to connect computers.
But HPN uses your home telephone wiring to send data at a different frequency than voice traffic. If you have telephone jacks near each computer you want to network, and those jacks run off the same phone line, HPN may be your best choice. Each device is then plugged into a phone jack. The network is very secure, because each home has a unique phone line running to the phone company. Each PC is then plugged into a power outlet.
