Orbi RBK753S and AT&T help

I have att fiber with the Arris bgw210 modem/router.

I am trying to figure out how to connect the orbi properly.

I still want access to the att arris wifi so that certain devices don't get connected to the orbi and then other devices go to the orbi.

I can't figure it out for the life of me.

I've read everything and not sure what to do.

    You have a couple options if you want to keep the att wifi running. 

    1. put the orbi's IP address in the att devices dmz

    2. put the orbi in access point mode. This disables its router functions and lets the att device run them. You can still use the orbi for wifi and ethernet.

      Slightly confused on this step, on the att setup page, I'm assuming I go to the IP Passthrough then I have options:

       

      Allocation Mode: Off/Default/Passthrough

      Passthrough Mode:DHCPS-dynamic, DHCPS-Fixed, Manual

      Passthrough Fixed MAC Address: choose from list

       

      Thanks for all the help

    Do what plemans posted, then name your Orbi WIFI SSID different than your Arris router's WIFI. You will then have 2 separate identifiable WIFI networks.
