DNS_PROBE_FINISHED_NXDOMAIN errors on RBR850
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 coup...

It's the AT&T Arris BGW210-700.

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-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

Thanks! I switched the router to IP Passthrough mode (the closest thing to bridge mode available for the BGW-210). I'll see if it makes a difference.

Anyone with a 8 series Orbi wanna try this?
