A Netgear powerline adapter network is a wired network but, most of the wires use in this network would be hidden. If we have a TV in a room and we want it to connect directly to our home router with an ethernet cable but, the home router is 30 to 40 away from the TV. In these situations, Netgear powerline adapter is very handy. http://www.mywifiext-net.com/
