Powerline internet is usually thought as an outdated technology. However, what people are missing is that it is not meant to be used as a solo broadband technology. Rather, it is used to supplement an existing Wi-Fi connection. The problem that most people have when they are using Ethernet cables is that they need to reach the modem. If you have electronics in the living room and then others in the bedrooms, it would be too complicated to wire them across the hallway. What you do is purchase a powerline plugin set of two. The two plugins will detect each other and you will not need any complicated installation.
Powerline uses the home's existing electrical wiring as the wired data network to transfer broadband. It is a simple and reliable technology.
