R8000P - DNS issues after firmware update

Did you factory reset and setup from scratch after applying the latest v.88 FW and see if DNS issues are present with IPv6 disabled? 

What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

Been monitoring my R7960P with v.88 loaded and no DNS issues yet however it's only been 12 hours..

Ya my ISP doesn't support IPv6 either.

Been running the 1.4.3.88 FW for the past several days now. While the DNS issues were lessened, they were still present, and annoying enough that I was strongly considering dropping back down again to the previous FW that I knew "worked" (1.4.1.68). That said, I saw FURRYe38's post about enabling IPv6 and, by George, that somehow worked. I'm not sure how it worked; my ISP seems hard set on sticking with IPv4, so I never bothered enabling it. But once I did, all of the random disconnects appeared to vanish. I'm curious to see if this somehow clears up a seemingly separate issue I've been having with one of my streaming services (or if it is, as I suspect, that the streaming service simply sucks).

 

This seems like an odd regression, to have this tied to the IPv6 toggle. The DNS service I use uses IPv4 addresses, so I don't see why this would make a difference. The most notable and obvious instances of DNS issues I encountered dealt with either (a) large services like Google or Facebook that have many servers and likely load-balance their domains across multiple IPs, or (b) CNAMEs that "redirect" from one domain to another. In the latter example, I have CNAMEs for a few of my domains that forward to Google services; these were often some of the main "victims" of the DNS issue and required several attempts to get the domain to resolve.
