Very simple to use and configure interface in French. By cons, at no time is specified and explained clearly an installation with router behind the modem. I search the internet forums and it is not simple. For those who will buy the product and install it before a router after you have set once the modem without a router to test, you have to re-configure a second time in "BRIDGE" to install the kernel before the router and configure the router with your connection settings. Otherwise it is a simple modem 'without wifi' at a very affordable price, very good product, which avoids to rent to life a "BOX".
