I do not have WPS button unfortunately on my router. That's why I tried to install according to the instructions. Unfortunately, the Internet addresses given were not working. Even with the supplied CD it did not work. Somehow (I do not) then it worked out, my router with the Medion Repeater to join. Now klappts, but not constant evenly on the signal strength. Nevertheless, I have much better reception, after I've tried a few sockets and therefore locations in my home. Therefore, two points are deducted.
