The stuff of your dreams; nothing to configure. Connecting a cable to the box and an adapter connected to a power outlet (multi moreover socket), plug the second adapter (here, a floor equivalent to between floor from the first floor) and cable on the second PC. The small lights turn green, the connection of the second PC on a grid very old, and multiple branches, is approximately three quarters of the initial rate (12 Mg Mg Instead of 15 at source) ... a short unexpected success !!! Congratulations to the designer!
