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...
Of course. I'm working from home too and have two VPNs running during the day for work so can't play around. :smileytongue:
For anyone in this thread, please disable any IPv6 Protocols ON the router. You might check your devices as awell and testi with IPv6 disable to see if this might help DNS problems. Let us know your findings.
OK, so did factory reset RBR850 and went through setup process (This has changed vastly since the very early days). The RBR is now sat behind my R7000 which is still in router mode for now. ORBI correctly detected that 192.168.1.0/24 was taken by the R7000 so assigned 10.0.0.0/24 instead. DMZ server set on R7000 to prevent double nat. Virgin Media Superhub3ac (Which I believe is an arris TG2492LG-VM) is set to modem mode. As messy as this sounds, it seems to be working. Whether this stands the test of time I am yet to find out, but all seems good, so 2 things to consider. Could operating in the 10.0.0.0/24 ip reange work better on the ORBI? Or is the DMZ mode of the Superhub3 no good. I will report back after further testing.
Lett us know how it goes. Will be interested to hear your results sometime next week if nothing happens.
One can use 192.168.0.1 as well. What I have on my RBR currently. Though no router in front of my RBR.

And we're back to the same issue. That rules out DMZ on supehub. Gonna try the suggestion of disabling all IPV6 functions.
