Hi, I have a basic Homestation ADB router and I bought a Wifi extender for the electrical installation of my home. It's a TP Link AV500 

I mounted it and it works very well but right now I have two different Wifi networks at home, the router and the repeater. Since the router does not have a WPS button, I should be able to enter the repeater via web to change the SSID and put it the same as the router. 

Someone can help me because I do not get it.

Thanks
