Belkin Powerline Networking Adapter F5D4073 connects your router with your computer without using Wi-Fi. - great condition, tested and used without any problems - very simple to use: connect one box to the router and a power outlet, connect the second box anywhere in the house to a power outlet and you have ethernet without having wires in the whole house - Original price: $250! Why do you need it? - You don't like Wi-Fi (electromagnetic radiation / Security) - You need a better ping for games - Your Wi-Fi is not the best, esp in the areas far away from the router - Your device has no Wi-Fi :o) I can send you the manual too, so no worries. As I said, it works like charm and is worth if you need a secure connection or when you try to avoid using Wi-Fi in general. Best, - Marcel
