So I've noticed that when I use my Orbi in router mode, I get a lot of DNS_PROBE_FINISHED_NXDOMAIN errors in chrome. The error flashes for a bout a second and then the page loads. This happens a couple of times per day. This does not happen if I use my ISPs router and set the Orbi to AP mode. So it seems like something is busted related to DNS with the Orbi where it occasionally fails to resolve something but then fixes itself. I've tried using automatic DNS as well as manually setting it to Cloudflare's DNS, but no difference. I've also flushed DNS and rebooted everything on my computer but again no dice (and again, this is not an issue when I let my ISPs router do the actual router stuff and turn the Orbi into an AP). Anyone have any ideas what this is about? I don't see anything in logs relating to this.

Yes. None of that stuff helps. The issue is 100% isolated to the Orbi itself.

Orbi in router or AP mode behind the ATT modem. This modem already has a built in router and wifi. This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAThttps://kb.netgear.com/30187/How-to-fix-issues-with-Double-NATCouple 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 https://community.netgear.com/t5/Orbi-AX/Orbi-AX-6000-and-AT-amp-T-fiber-gateway-issue/m-p/1890125/highlight/true#M2756internet-john wrote:It's the AT&T Arris BGW210-700.

Anyone with a 8 series Orbi wanna try this?https://community.netgear.com/t5/Orbi-AX/New-RBR850-RBS850-Series-Firmware-Version-v3-2-17-12-Released/m-p/2043132/highlight/true#M11376

Try this. I have Beta version (similar version number) on 7 series and my dns issues seem to be resolved
