r wifi doesnt work

Solution
It should have a reset button. Hold it in for 20 seconds or so and see what happens. If ethernet works, you should be able to log into it and check your wifi settings.

Well obviously you don't want to use that site. Why don't you try the Sagecom site?

Just looking at the picture of the router, it looks like there's a button for wifi on the right side of the front panel. Try pressing that.
