We've used powerline networking adapters ourselves to reach areas where our wi-fi network signal was poor, and they work wonderfully. One advantage to this device is that it includes a built-in switch: you can plug up to four Ethernet-capable devices into the remote adapter.
This is what is in the box:
one Linksys PLE400 Powerline AV 1-Port Network Adapter (to connect to the router)
one Linksys PLS400 Powerline AV 4-Port Network Adapter (the remote end)
Quick Install Guide
two Ethernet Cables
Powerline networking, for those who don't know, works by routing the Ethernet signal through the power circuitry in your house. Note that there can be problems if the remote end and the originating end are not on the same circuit, but if they are, the speed and reliability is excellent.
These adapters advertise speeds of up to 200Mbps. Note the words "up to," however. As Linksys says,
Maximum performance for the Powerline AV Network Adapter is derived from HomePlug Powerline Alliance HomePlug AV specification. Performance depends on many factors, conditions and variables, including volume of network traffic, home wiring construction, operating system used, mix of networking products used, interference from other electrical devices, age of home wiring, wireline range and coverage as determined by wiring route or path between devices and other adverse conditions. Power outlets and electrical wiring must all be part of the same electrical system.
Naturally, there are always caveats. Despite the advertised speed of the new 802.11ac wireless networking standard, the same can be said about wi-fi. There can be interference among powerline networking adapters, and there can be interference in wi-fi, too.
In fact, some older houses (really old, mind you) use material similar to chicken wire in the walls. These are the perfect material to block wi-fi (like a Faraday cage), and thus make some older houses -- such as those in San Francisco -- a bane to wi-fi.
To be clear, the best way to network is with standard Ethernet cable, not wi-fi or powerline networking, but it you can't do that, this is a good alternative.
