Intermittent DNS lookup failures on RBR850

This has been previously reported and plaguing other Orbi AX customers. IMO it is not something particularly wrong with your hardware unit and a problem in the latest firmware.

I see it very often while web browsing in my browser, where it quickly refreshes and tries again to display the page. I also see it exhibited when I go a URL bookmark for this Negear Community forum and intermittently (maybe 5%-10% of the time) it displays some Netgear forum Authentication error page and simply retrying then gets me in.
Yea when it's really bad the Chromebooks will fail the "internet" check (always DNS) which makes the system think the Internet is down when it's not.
I've also seen Windows fail this simlar check and think the NIC has no network connectivity BUT this doesn't stop it from working.
