R8000P - DNS issues after firmware update
For some unknown reason, the automatic firmware update did not work on my R8000P router, and I found that I was one version behind at 1.4.1.68. So I manually updated to 1.4.2.84. After the update, I found that I was having DNS problems on multiple devices. These problems persisted for weeks. I tried specifying different DNS servers, away from my ISP's servers, but the situation did not improve. So, I downgraded the firmware back to 1.4.1.68, and the DNS problems went away.
Has anybody had a similar experience?

Re: R8000P - DNS issues after firmware update
quite a few people have posted issues like this across mulitple product lines. So don't feel alone. I'm sure netgear is working on it as we've seen it on multiple products.

Re: R8000P - DNS issues after firmware update
Same here. Recently updated to V1.4.2.84_1.3.42. Ever since, I've been consistently getting failures that look like DNS failures. In web surfing, it takes multiple refreshes of the page before it actually connects, then everything is fine. This is glaringly obvious with my Google G Suite sites, which use CNAMEs and thus several DNS look-ups before you actually connect to an IP. My Thunderbird hasn't connected to GMail IMAP at all since the router update; Google tends to have lots of IPs and short DNS TTLs, so I'm guessing this is related. (Nothing has changed with my account or authentication settings to cause this to fail.)
The only addition I would make is that WiFi connected devices seem more susceptible to this than hard-wired devices. Some sites won't work at all if I'm on WiFi, but if I switch to a desktop with a physical cable to the router, the site works much more reliably. (It may still take several refreshes before I can load the site.)

Re: R8000P - DNS issues after firmware update
You'll need to downgrade back to what was working for you.

Re: R8000P - DNS issues after firmware update
So my choices are a working DNS but massive security flaws, or increased security but DNS doesn't work?

Re: R8000P - DNS issues after firmware update
Is Netgear working on a solution?! Has anybody heard? I'm very dismayed that such a blatant and pervasive problem has gone unaddressed for many weeks.

Re: R8000P - DNS issues after firmware update
I know they're aware of the issue. And I've seen beta fixes for the R6400/R6700 that a Mod sent to a few users.
So I have a feeling its in the works but they don't release any details on ETA's.

Re: R8000P - DNS issues after firmware update
Can confirm that downgrading to V1.4.1.68_1.3.28 "fixes" the DNS issue. Fortunately, the security flaw V1.4.2.84_1.3.42 is supposed to fix requires access to the local LAN, so I guess we'll just have to live with that for now. (Of course, anyone who follows INFOSEC news knows there are ways around the "local LAN" issue. Just make sure everyone in your household/office knows to browse safely.)

@kerryland Pihole works pretty nice. I've got one but its running in a docker container on my server. Love how much it blocks.

Re: R8000P - DNS issues after firmware update
Any luck with this, Netgear? I've had several attempts to add this comment... This is my first and will be my last Netgear device. It would appear you cannot afford to hire reasonable talent. I mean, seriously, DNS issues in a router ?! You're kidding me right? Sounds like piston misfires in an engine. Would you buy a car from that manufacturer ?
Fix it !

Re: R8000P - DNS issues after firmware update
Several more months on and still no fix or new firmware update? For real? They can't even make a firmware version available that's between 1.4.2.68 and 1.4.2.84? This is not good. Is this model officially end of life and there will never be another firmware update or hotfix? Bueller?

Re: R8000P - DNS issues after firmware update
What do you mean between .68 and .84? There was probably nothing made or developed for release between those versions so if there was, was not mented for public use.
For now, users should keep to v.68 or .v62 for now. Fixes and FW development doesn't happen over night.

Re: R8000P - DNS issues after firmware update
Well it is what it is. I've seen some mfrs take 9 mths to a year to come out with new FW updates. You'll have to be patient.

Re: R8000P - DNS issues after firmware update
New firmware was released this past week (v88). Installed it this morning and so far so good, no DNS issues/sites not loading. Will continue to monitor throughout the weekend, but hopefully it's been addressed and we can go back to being secure and functional!

Re: R8000P - DNS issues after firmware update
Yes, I had similar DNS problems.
My solve/resolve tied back into ENABLING IPv6 under the advance settings. See my thread below
Hope this helps you!

Re: R8000P - DNS issues after firmware update
ps. This is my second attempt at this post (last time I mentioned a specific brand). I hope the moderators aren't banning statements like this.

Re: R8000P - DNS issues after firmware update
Yes, I completely agree, I had struggled for months on DNS this issue and almost gave up on my NG.
There has to be a quicker way to engage with NG DEVELOPERS on prioritizing with getting these issues resolved. (Moderators, if you have any ideas or suggestions, that would be great!)
And a big Kudos to the expert moderators supporting this group, I appreciate all the help & solutions they offer!
Kerryland, Thank you for responding with your comments!

Re: R8000P - DNS issues after firmware update
Subject: "Known DNS problems with solutions"
Summary: Several people reported DNS issued related to PROBE or non-response from websites
NG pending actions: NG engineer team is aware of the problem, they are working on it. It does take some time for development and testing. In meantime, users can try enabled IPv6 to see if this corrects the DNS problem or revert back FW to what was working.
Please be patient.

Re: R8000P - DNS issues after firmware update
Downloaded new firmware to V1.0.4.84-10.1.84 and now have the same issue on all three devices. How do I get the "old" version installed?
I am a relative novice when it comes to wireless router set up.

Re: R8000P - DNS issues after firmware update
Did you try this version of FW?

Re: R8000P - DNS issues after firmware update
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.

Re: 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.

Re: R8000P - DNS issues after firmware update
After weeks of constantly fiddeling arround with my pihole, windows software/firewall and stuff...
I thought it was a user error....
Also my alexas multiroom does not bugging out after 20 minutes now.
Everything seems to work now. Pihole works and no more reloading webpages... since 1 hour it seems to work.
