I managed to install even without being an expert

It was difficult to choose because I know nothing. I relied on the reviews of other buyers. I received the product very quickly. I moved after some trial and error. I have a Freebox Revolution. I plug the device 'mother' (without the house symbol) on my box with an Ethernet cable (supplied) and on a separate outlet. Then I branch to another device (with network and house symbol) when I needed wifi on a single socket (not a power strip). I pressed the home button and went to press the small gray button on the parent device that flashes a green light. After a while the light is solid green. On the wireless unit, the house is solid green and solid green network. Then I plug the second wireless device to another area of ​​the house, I pressed the button 'house' and the unit is synchronizes itself. The network works perfectly! I make this description as I have a little galley believing that I had to synchronize the network with my Freeplugs, but not all. It is two separate networks and it works very well.
