Intermittent DNS Errors and WiFi Issues
I have had the Orbi AX6000 for a few months now. While there are many things I love about it (great wifi coverage, great speed, looks nice, software, ease of setup, etc.), there are two very frustra...

No changing the DNS configuration is not the solution. The DNS servers (i.e. Google / Cloudflare) etc. are not the problem. The problem is the actual Netgear DNS server/firmware. So you can be changing your DNS configuration all day, it won't fix a thing.
You can think of this as a car. If the engine is broken. You can swap the benzine for another type of benzine. The engine still remains broken. Now Netgear should fix this engine, instead they just say please try a different type of benzine as the benzine you now use might not be good for the engine. So as a user you are spending a lot of time changing and trying out different types of benzines. Which in the end, is actually wasting your time. As the problem still is: the engine is broken.

Correct.
This isn't browser related or DNS Server related.
This is my experience:
if you look up a website... for example go to whitepages.com
the initial lookup is a miss.... then the browser refreshes automatically, and resolves.
This is almost like the local DNS cache on the router is returning info and then retrying resolution.... it's not in the local cache on the router... so it fails. then goes out and resolves.
If you go to that same website again, on any other device or browser, there's no dns lookup miss.
So I'm thinking this is an issue at the router, doing the initial DNS lookup... somehow the router is giving a response to the request... which causes the error screen, but then immediately resolves it and pushes the result again to the client.
That's my interpretation, anyway.
This happens for me across devices, and across browsers

This is a shot in the dark, but since some have had temporary success rebooting the router, is there a way to flush the router's dns cache manually - like through telnet command?
I actually DON'T have an Orbi AX, but it's on the way, so am interested in this problem in case it arises for me. I'm thinking if I see it within the return period (direct from Netgear - 30 days, I believe), I'm not going to even bother troubleshooting and just return the thing.

Ya NG removed the telnet funtion on Orbi AX.
Oh to let everyone know, just saw my first ever DNS_PROBE_FINISHED_NXDOMAIN error two times while on the NG forums this morning. The first error appeared in the browser and I had to refresh the page, the 2nd was quicker and the browser continued to the page. I've not done anything else. Thought we has a quick power bump this morning so my 30+ days of operation seeing in the debug.htm is now reset.
Looking to see if this happens again. I'm glad I can join the croud now whos been experiencing this. :smileyhappy:
