I don't know Italian that well, however I believe you have the correct configuration on the Orbi system. Automatic DHCP for the WAN side. You can set automatic for DNS or use custom DNS there.

Hi thanks for the reply, yes currently on the current modem router of the ISP I have disabled the WiFi and I connected as said the orbi to the LAN port. What I am interested in knowing when I connect the orbi to the LAN port of the new modem/router of the new ISP the orbi gets the IP address from the DHCP of the modem/router of the new ISP and everything works as it does now right? The new ISP does not ask for username and password to access the connection. Obviously also on the modem/router of the new ISP I will turn off the WiFi first. Thanks.

Even though you disabled the WiFi on the ISP router, the router is still running on the ISP modem. So would need to either set the ISP modem to bridge mode to disable the ISP router, if it supports it or use the DMZ for the Orbi router. Setting a IP address reservation for the Orbi router on the ISP routers web page so the IP address doesn't change for the Orbi router. Configure the Orbi router for DHCP on the WAN side that is all that's needed for the ISP connection. You'll need to contact the ISP to check on bridge mode support and ISP configuration if you want to put the ISP modem into bridge mode.

Thanks for the reply, so I leave the settings on the orbi as in the photos I posted right? Even now on the modem/router of my current ISP I have reserved the IP address for the orbi. thanks.
