You can now connect your computer to the Internet without wires.
Two products are needed..
1) A device that plugs into your telephone socket and transmits and receives your Internet connection by radio signals. Devices that do this are called Wireless Routers and Access Points.
2) A device that plugs into your computer that receives and transmits information to and from the Router or Access Point. These are called Wireless LAN Cards or Wireless Modems.
