Intermittent DNS Errors and WiFi Issues

This is still occurring for me, months later.

However, I believe I know the problem and possible solutions.

In regards to my intermittent DNS error message. I'm using the "NETGEAR Orbi RBK853 AX6000 Tri-band WiFi 6 Mesh System- 3 pack". Still might be different for others?

1) The Netgear Orbi AX series has builtin NETGEAR Armor powered by Bitdefender. Which is great if you wish to use that, but becomes a problem if you don't. I have Kaspersky Internet Security already and don't need it. This feature seems to call out and loop around the DNS request, to check with Netgear Armor for malicious and phishing URLs, etc. Can it not do that, if an opt-out is offered or if it's disabled under the router admin? That loop around causes a DNS delay, even if Netgear Armor is disabled by the looks?

2) A single DNS failure call from a webpage, will be displayed over top, even if the rest of the webpage is loading fine.

As mentioned before...

For even this website: https://community.netgear.com/t5/Orbi-AX/bd-p/en-home-orbi-ax

It will sometime gives a "DNS_PROBE_FINISHED_NXDOMAIN" message.

Yet I've narrowed it down to a possible URL it's attempting to load with the webpage:

https://cloud.github.com/downloads/lafeber/world-flags-sprite/flags32.css

Press F12 on your web-browser and look under the networking, refresh the page with CTRL + F5.

You might notice a single or multiple files showing (failed) net::ERR_NAME_NOT_RESOLVED.

Go to that link directly and you will get the message: 

Hmmm… can't reach this page. Check if there is a typo.
If spelling is correct, try running Windows Network Diagnostics.
DNS_PROBE_FINISHED_NXDOMAIN

That's the actual valid error.

However, it doesn't matter for the rest of the website that it broke. The rest should load fine and work normally. On almost every other routers and meshes out there that is ignored and skipped over, but with the NetGear Orbi AX it displays that message over top of the entire webpage for at least a few seconds or has you needing to refresh the page to display it.

Why is it removing my post? Too big, considered as spam or contains the valid information to fix this problem? Can mods of the website still see it at least?
