Thanks you for yours answer. @vince : I am such of the IP. As already said, turning of the WS let the ping without answer. And the four Devolo are recognize by Advance IP Scanner. They have a different IP than the WS.
@Robert : I will learn how to set up an access point, and come back with the results.
