We Really Like this WiFi Range extender from Netgear, its as near to “Plug and Play” as anything seems to be in reality and its really great for getting the signal to that far off corner of the house that you use as your office>

It simply plugs into an electric power point somewhere it can “receive” your existing WiFi signal and “reflects” the signal on another chunk of the way to your problem point.

It is “universal” in that it works with other manufacturers routers and network adaptors and is “N” Standard giving it a decent range.
