Turn your home's existing electrical circuit into a high-speed network with a Powerline adapter, easy plug & play operation. A network Powerline adapter uses the electrical wiring in your home to transfer the broadband signal from one device to another. Basically, plug one device into your router and mains power, then a second (or multiples) in another device, this gives you a direct connection to the router and usually the same speeds. To work Network Powerline Extenders have to be on the same electrical circuit. Some adapters are plug through, you can plug a device directly into them, whilst they still operate as a wired supply to a device. Other Powerline adapters can accept multiple wired devices, some models can even output a W-Fi signal, so you would completely covered in that area.
