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...
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?

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.

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.

Around here the issue shows up on Frontier, Spectrum, and Wow. None support IPv6. So it makes sense, if you use their DNS servers, the DNS timing errors could exist.
Ok, yes seems to be somewhat ISP specific.
I'm on Sparklight here and have not see this as of yet. I let the RBR auto detect ISP DNS.
Wondering if I should try your configuration and just see if anything happens on mine this weekend.

I let the RBR auto detect ISP DNS as well. I'm only referring to the IPv6 settings page.
But I was getting the intermittant DNS failures, until I configured IPv6.
Ok, thanks for the clairifcation. I'll try your config out on mine and see what happens.
OK so here is a new trial. I have factory reset the ORBI and put it back into router mode. Again it has correctly detected I am still using my R7000 as a router (So that I dont get lynched by my partner (I have migrated the SSID and password over to it so she doesnt suspect a thing) and changed the IP range of ORBI into 10.0.0.0/24. Orib Internet port has been added to the DMZ of the R7000.
According to all sources, Virgin Media do not support IPV6 but I thought I would go to the IPV6 settings of the ORBI and select auto detect. On clicking apply, it returned as 6to4. I dont really understand the IPV6 side of things, but does this suggest some support of IPV6 on Virgin Media? Or is this just because I am connected to my R7000 which definitely supports IPV6. Touch wood, o DNS issues so far.
As ever I will monitor this. Like I say, dont really understand the workings of IPV6 but assumed if auto detect could not find any IPV6 support, then it would have disabled it again?
EDIT: My WiFi performance is compromised as the R7000 with both its radios enabled is within 12 inches of the ORBI. However this hasnt caused any drop outs

No support on Virgin, Orbi or R7000, but full WWW support. Now you have to pick public IPv6 DNS servers and finish the configuration.
I suggest turning off the WIFI on your R7000 router, or make sure it is on different channels than the Orbi.
- Yes. Ideally, if I get ORBI behaving in router mode, I will disable all but the 2.4ghz radio on the r7000 and put it back in ap mode leaving rbr850 to make router mode. Sadly I have one device that won't connect to ax networks so have to keep the r7000 2.4ghz alive at 25% so it can still communicate with that one device
You can do this, just keep one router on channel 1 and the other on channel 11.
