With WIFI problems, I bought the adapter Devolo CPL Dlan 500. While there, great. We brabche the Starter on a socket and connects it to the Box. Then you plug the receiver into a power outlet near the desired ring road (in another room or another floor), you install the software, you press the little interrupeurs each adapter, and there, she joy it works. And in addition, the staff of Devolo responds quickly to our request. I had misplaced the CD with the manual, he sent me this book is by return email. So congratulations on the line.
