What is the Mfr and model# of the ISP modem the NG router is connected too? Built in router here already? If so, 

This would be a double NAT condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT
Couple of options,
1. Configure the modem for transparent bridge mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router. https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point and https://www.youtube.com/watch?v=H7LOcJ8GdDo&app=desktop

Not too familiar with Wi-Fi jargon so I'll answer to the best of my ability.

 

The modem AT&T provided is an ARRIS BGW210**. I believe it is a modem/router (see link below) so your assumption of Double NAT is probably correct. The Orbi is currently connected to the Arris via ethernet, so yes, we have 2 Wi-Fi networks across the house, one for the Orbi and one for the Modem. This is a similar setup as before with Xfinity. The Orbi was connected to the Xfinity modem/router, but that never caused any problems with my PS4.

 

I'm going to try doing the 3 things you recommended, however, I'm not that familiar with it so I'll probably need to contact customer support to walk me through it.

 

 

 

 

 

** I think this is the same ISP modem on Amazon (https://www.amazon.com/BGW210-700-802-11b-Wireless-Gateway-REQUIRED/dp/B07BZC72TB)
