If you need to run a wired connection over a long distance in your home, a HomePlug can be really smart. A HomePlug uses the mains to power the network so you do not have to run a cable throughout the house.
A HomePlug is easy to set up. You plug one part into a wall outlet and connect a LAN cable from your router. Just like the first part of the HomePlug, connect the output to another outlet and insert another LAN cable into the product you want to connect to the Internet. A desktop computer, a smart TV, a NAS server or a game console are the devices most often used with a HomePlug.
If you want to spread the connection from the HomePlug, you can use a switch. The switch allows multiple devices to use the same wired connection over the mains to get a better internet connection than wirelessly via Wi-Fi.
Some HomePlugs come with a network extension built into the homeplug output. This is very clever, as in addition to the wired connection via the home electrical system, you get a better wireless connection in all rooms.
