In the claimed version, router-LAN adapter (white)-powerline-WiFi adapter (blue) does not work. Only router-Lan WiFi adapter-powerline-LAN adapter that is in the remote room WiFi (blue adapter) No, only Lan (white adapter), to connect pc. And in the instructions named such a scheme is described (WiFi next to the router), and in the description of the product on the site just the one that does not work. Why put the WiFi adapter next to the router, in which there is a WiFi mystery. And the WiFi signal is very weak, with 5 meters without obstacles falls by 80%. The seller knowing about it promised to change the description, but did nothing. The computer in the remote room connected, works. And I wanted WiFi. Made a small discount on another repeater. But, sociable.
Received in France after 12 days. To configure, connect by Ethernet the blue CPL to the router. Then connect the blue and white CPL to an electrical outlet in the same room. Press the pairing button for 2 seconds on the blue CPL then for 2 seconds on the white CPL.
For use, connect the white to Ethernet near the router and an electrical outlet then the blue on an electrical outlet further in the house. The blue CPL is ready to emit Wifi without signal loss.
