After trying many solutions to extend the reach of my network (old router as DD-WRT) with a Freebox Revolution, I finally bought this product which is childish to set. The web tool is clear and simple. I advise to follow the recommendation of the tool ie to create a separate network such as network and réseau_ext. Security settings can be identical or strengthened (when the terminal practices floods the neighbors or the street) The reason is that devices including phones will connect to more powerful without creating confusion between ssid. To have it tested, I found this clearer and simpler solution. We know how it is connected. The gain range is variable and depends on the configuration of the current network (walls, microwave ...) The placement can be optimized thanks to LEDs on the front panel and non-removable antennas. I took three in total! It can indicate the terminals to connect to the router or connect to one of them in series.
