Starting up ...

Once connected, the WiFi is perfect. (So ​​much so that repositioning the Devolo, I deleted the wifi of the Box)

However, the document is not clear for no initiation step.
For my case: Start with CD and provides a Livebox configuration (last generation) was catastrophic.
The box stopped working every wired network connection on the PC (in either case Devolo), thus resetting the box every time> 'misery and waste of time!'
I even consider returning equipment (after three hours of essays)

BUT this is what he would have had to do and so read the instructions on pages 40 ...
(4-step and 5 minutes later)

1 Master Case (without front button) just a little button below to log in first (in the box) and decision (of course)
Slave Case 2 (with two face buttons) to connect the second (still in a socket)
3 Press a (good) second on the small button of the master box.
4 Press a (good) second on Wifi button (top) of the slave case (for one minute)
after a few seconds you will receive a new WiFi signal (more powerful than that of the Livebox for info)
FINISHED!

You can disconnect the wireless by pressing the button (wireless) of the slave box to extinction of this one.
(In standby mode, it flashes regularly: normal operation)
A new impetus the fate of his vigil.

One more reassuring technical information: the master box is connected into a power (what not to do) and the slave case is when with him into a wall outlet. This is an old house in 1900 with a power grid that it's complicated over the enlargements (There are three important Eclectic derivations) AND IT WORKS!

On the same network, there is the presence of a Logitech monitoring network and I observed no conflict.

The next step is to connect a second slave housing to connect it to the TV by a wired system (networked)

Well, I hope this post will be your source of additional motivations for buying real Cpl solution
