Having trouble signal stability with Freeplugs my Freebox Revolution I replaced them with a pair of DLAN 650. I should say only partially because the power jack of Freeplugs remains necessary for the supply of server and player . So I have to juxtapose the two housings. The result is much better than I expected. Everything works perfectly. The presence of a socket on each adapter eliminates neutralize an outlet and is used to connect other devices without affecting the CPL flow. Important advice! for pairing your two housings made a very brief press (less than one second) on each of the buttons on boxes or it does not. I had to call the Hotine of DEVOLO to find out. I got a counselor quickly and was friendly and very clear.
