The Powerline AV Ethernet Adapter Kit from Netgear allows you to extend your home LAN without the need for costly and time-consuming wiring. The kit includes two wall-plugged Ethernet bridges; each plugs into an AC wall outlet for network connectivity. The system can communicate at speeds up to 200Mbps, allowing you to leverage your home's electrical wiring to set up a network. You can even use it as part of a wireless network to help eliminate "dead spots" in coverage.
