There are many reasons why your home Wi-Fi network doesn’t reach into every part of your house. The router’s wireless signal might not have the range to get to the furthest rooms, or the walls might be very thick and heavy, which makes it difficult for Wi-Fi to penetrate. So maybe you need to make a cabled connection to one of the router’s Ethernet ports, but don’t want to trail Ethernet cables through the house. Powerline adapters are a potential solution for extending both your wireless and cabled network, using your home’s electrical cabling as data cables.
A powerline adapter kit comes with at least two plug adapters, which are small devices that plugusing the household electrical cabling as data cables. If the adapter that’s not connected to your router offers a Wireless Access Point, a Wi-Fi enabled device can connect to it and get online (and also onto your local network, of course), by connecting wirelessly to the powerline adapter. This adapter then connects to the router’s powerline adapter, through the house’s electrical cables, and thus to the router. It sounds complicated, but it isn’t. It just works.
