Summary: ZyXEL PLA-401 200Mbps Homeplug is a good little invention, it offers high speed network transfer speeds through you normal mains power. You may ask why you don't just use wireless, which is fair enough but if you want a connection somewhere that there is poor signal then the home plug is a sure way to have a stable uninterrupted connection and the speeds can be a lot quicker than wireless.
Summary: Bought 2 of these (so 4 plugs) in an attempt to rid myself of wi-fi as far as possible and get proper media streaming working around the house. I have always toyed with the idea of a proper LAN network, and thought i`d give these a go as an easier, no cable option. The packaging advertises "plug and play" functionality, although I found this wasn`t quite the case.
Pros: Easy to use, works perfectly
Cons: Encryption awkward to set up, initial difficulty with ip address selection
