WPS Activation

I followed exactly and scrupulously, and it shows an error on the Freebox Revolution when I am on WPS...

Hi,
the Wi-Fi radio signal won't improve with fiber.
After that, we don't know what your repeater is, at least we don't know the model, but fortunately there's a way to connect them to the box without WPS, you just need to know its WPA key.
For that, you need to connect to the repeater's interface, find the box's Wi-Fi network, and enter the key.

and ... There you go!

Hi,
I have this model http://www.connect-we.fr/boutique/559-repeteur-wifi-we-300m.html

Unfortunately, I don't have a manual, and I don't know which interface to connect to... However, I see the signal with its name in the list of Wi-Fi networks found on my computer and Android, but when I click on it, there's no internet connection.

It is written on the site: Capture the internet everywhere in your home!
