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...
I presume this is for ISPs that have IPv6 support?

login to orbilogin.com Advanced, Advanced, IPv6. I setup the following:
6to4 Tunnel, Remote 6to4 relay Router set to "Auto", IPv6 Domain Name Server (DNS) Address set to "Use These DNS Servers". I chose Google's public IPv6 DNS Servers. IP Address Assignment set to "Auto". Tested using test-ipv6.com
As soon as I correctly setup IPv6, and passed the tests, I no longer see any DNS issues.

No, this offers IPv6 support using 3rd party 6to4 tunnel public DNS servers like Google and Open.
My ISP is WOW and they currently do not offer IPv6 support.
I also forgot to include the final setting. In IPv6 network protocol settings on my PC, I checked IPv6 to "obtain an IPv6 IP address automatically" and checked "used the following DNS servers", and inserted the Google public IPv6 DNS server addresses.
So if you set this up for 3rd party IPv6 tunnel, you don't see DNS issues. However, if you disable IPv6 on the RBR and PC enstirely just using IPv4 DNS or auto detect ISP DNS on the RBR, do you see this DNS issue?

Yes that's correct. At least it is for me using Google public servers in the U.S., and setting up the router and devices, the way I described.
I did not try any other servers, but I asume it will work, with any public 6to4 tunnel compatible IPv6 servers.
Since I use IPv6, I never tried disabling it in my settings, so I'm not sure if the DNS issue is still present. But if IPv6 is set to auto and not disabled, the intermittant DNS resolving issue occasionally pops up.
Being as IPv6 is on by default, and many, including some of my clients, are complaining about the same DNS issue, with the RBR750 and 850, I concentrated on solving the issue when IPv6 is enabled.
Ok, thanks for the details. Hopefully this can help for those seeing this issue. I for one am not an not sure why. I feel this is a ISP/Orbi specific issue. I recently changed my ISP modem as well and stil not seeing anything remotely close to all this.
