Cannot enter configuration page (Router WNDAP360)

Hi, I'm having issues trying to enter the control panel of this router. Internet works, but I cannot enter the panel to set up a password, my WiFi is not protected right now.

The NetGear Router (WNDAP360) has default settings (hard reset with the button before installing) and it's connected to my Modem TIM. 
All my WiFi devices can connect to the Router, so it works but in any on them I cannot access the control panel. 

As default, the IP address for entering the panel should be 192.168.0.100 but when I try to connect to it I can't get any connection. It loads for like one minute and then says it cannot reach the website.

I also tried download the app Nighthawk, it does not detect the Router even if I'm connected to it.

If I try using the IP 192.168.1.1 i get into the Modem TIM webpage and I cannot do any change to the Netgear router from there.

How can I solve this?
