RBR20 magenta with AT&T internet

Hi folks, seeing a weird issue with my parents’ Orbi. Their ISP is AT&T and I’ve turned off all wifi radios on their router. I connected the Orbi router to it, and put it into AP mode. And things work well for a while (weeks). Then out of nowhere, the Orbi router seems to lose internet - pages stop loading, the router shows as Magenta on the Orbi mobile app, while the satellites remain green. Restating the Orbi router once or twice seems to resolve the issue. I thought it may be an intermittent issue with the ISP, but the issue doesn’t seem to occur if I just use the AT&T router without Orbi. Am I missing a setting somewhere? I have the same setup at my own home but with verizon Fios, and never get these issues.

    What Firmware version is currently loaded?
    What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too? Built in router here? If so,

    This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT

    Couple of options,
    1. Configure the modem for transparent bridge or modem only 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

      Orbi firmware 2.5.1.16. AT&T router is Pace Plc 5268AC. And yeah I’ve already done option 3, as per my original message.

        Be sure your using the WAN port on the RBR for the connection to the ISP modem. 

        Be sure it's getting a good IP address from the ISP modem. 

        Be sure your using a good quality LAN cable. CAT6 is recommended. 

        Power OFF both ISP modem and RBR for 30 seconds, then back ON with the modem first then RBR. 

        Has a factory reset and setup from scratch been performed since last FW update? 

        Try settting a static IP address ON the RBR for AP mode.
