Reply DNS not working on my R7800. Anyone hear of this?

Aspirant DNS not working on my R7800. Anyone hear of this?

I can't access websites or ping them if I set as the primary DNS on my R7800. 


I'm fairly certain it's the router since if I use different servers, then change the DNS on my PC to, it works fine. works though. 


Has anyone seen this or have any ideas?

So are you saying if you change the primary DNS on router to it will work? That does not really make much sense as they are both the same DNS provider and this particular one claims to always have a server available.  

Besides setting the DNS for testing on your PC you can also use command line using nslookup. Would look like this:


Non-authoritative answer:
Addresses: 2607:f8b0:4009:810::200e

That will tell you if the DNS server is working. If so and things work if you change the router primary DNS to and that works makes no sense to me why would not work. Maybe a finger check? Make sure in your testing that when you test on your PC you clear the local on PC DNS cache as that can give you false information for testing. PC will check local DNS cache first and not even use the router DNS for lookup if found locally. This will include a negative lookup response.  Can clear DNS cache this way.

You may already know the above, so sorry if it sounds like I don't think you know.
