Intermittent DNS lookup failures on RBR850
Intermittent DNS lookup failures RBR850 I've been using the Orbi RBR850 for several months now and I'm constantly having issues with DNS that I've NEVER experienced with any other router I've ever u...
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
This isn't the problem. The modem is a 'dumb' modem, doesn't route, dhcp, dns etc.
Are you using custom DNS addresses or letting the RBR auto detect DNS from your ISP?
Custom, using openDNS as mentioned (was using the same service on my old netgear router I upgraded from and the same modem and never had this problem)
Has a factory reset and setup from scratch been performed since last FW update?
No factory reset yet. The problem is annoying but this MOSTLY works.
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.
