Transfer rate as fast as directly to the router. (Phase is the same)
Press plugging, cable to the router (Fritz box), at the equivalent of cable TV, Anlern button on the part of the router, then within a minute the Anlerntaster the counterpart press (if necessary for two, if you are bad on foot). Work right away.
So true Plug'n'Play!
And lost the nice, it's no outlet
