I upgraded, recently, my broadband package to BT's Infinity. This means that my PC (upstairs) is now remote from the master socket. My original intention was to wire the PC directly to the master socket with a long and complicated network cable....until I read about using the existing electrical wiring as an alternative for a "wired" connection. I bought the DEVOLO pass through starter kit and now I have a very good system without the need for messy new wiring. Neat solution. No doubt. And it works first time.
