If you plug the parts directly into the wall socket, it works perfectly, I easily managed 50 Mbs with it.

The installation did not bring the desired (promised?!) effect for me either.
I no longer use it.

Unfortunately, it did not work for me. The goal was to link two rooms. But these are apparently on two different circuits and it didn't work. I then passed on the kit set because it was useless for me. Too bad.
