How longs it been going on?
The last firmware pushed out seemed to cause a lot of dns issues.
Most fixed it by downgrading a version and are now waiting on netgear to update.
have you tried this?

I am also a Spectrum customer with very similar DNS issues. However, VPN is not a solution for me.
My question is fundamentally if it has been established (within this forum or otherwise) that this type of issue is entirely within Spectrum's realm, or is the consensus currently that this is squarely a Netgear Router problem??
Acting on other relevant posts in this forum, I downgraded 2 days ago to V 1.0.4.102_10.0.75 from the currently available V 1.0.4.126_10.0.102 which had no positive effect on this issue.
I have 3 windows 10 PC's, 2 Roku's, 2 LG TV's with WEB OS, 2 Android smart phones, all of which singularly only get online with their adapter settings using fixed Google DNS settings. I had this problem now for over a year and am about to dump this router.
While I was getting by with this arrangement until now, my brand new Tesla’s wireless network adapter is unable to connect to my network/internet. “unable to get IP address”.
No interface exists to its network adapter to make any DNS changes. It is using “automatic DNS mode”. Strong wifi signal at car. My laptop connects properly at same physical location (albeit with Google DNS).
Doing more investigation, I noticed that router internal time is Sep 22, 2020 and is stuck there. Also had eastern time zone selected.
Was able to correct time Zone, but no effect on date/time.
Automatic adjustment is selected.
Default Netgear NTP is selected.
Could incorrect time stamp be behind this DNS issue?
Tried using “time.cloudflare.com” to no effect, router apparently never connects to any such site.
Multiple Modem/router factory resets had no effect either.
Router user interface after login shows RED “no Internet” on Basic Home Tab. However, when selecting the “Advanved” tab, it shows the internet port with a green check mark and I can get online without any issues as long as I use google DNS on the adapters.
It appears that some router internal portion thinks it has no internet and (perhaps) this is why it never updates its date/time?? A case of “split” personality?
Welcome any useful input. Thanks.

Yes, the ntp time issue could impact your DNS response. The Netgear time server always seemed inconsistent in its response to my location. Sometimes it responded quickly and sometimes not.
Do a search for ntp servers. Several options will come up if you are in the US. One is pool.ntp.org. I use this one in Washington state and it works fine with OpenDNS.
Here is a link: https://timetoolsltd.com/information/public-ntp-server/
From the government, try time.nist.gov.

Problem solved. Moved to a new house. Still have Spectrum but everything works here. Looks to me like there was a connection issue at the old house.
Note, I was moving anyway, I didn't buy a new house to fix the issue.

Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.

re: the time stamp issue.
The (suspected) problem I'm having with my router is this "split personality" where it thinks it is not connected to the internet on its Basic Tab and yet showing a green check mark on the advanced tab at the same time. AND I do have actual internet access. This could potentially prevent it from even looking for a time stamp.
Since I already tried both with and without the Netgear NTP site address, it never connected even overnight. I don't see any hints on how this could be forced so you could properly test it with other site addresses. Resetting it certainly did nothing to the time stamp.
By the way, does anybody know if there is a specific entry method/synatx when typing in an NTP site address in the provided text box??
Thanks

Only the ones provided on the web site at the link I provided above. I do know the simple syntax like pool.ntp.org is consistent between both Netgear and ASUS routers.
Another suggestion would be to re-flash the same version of firmware over the top of what is in place. Maybe something corrupt was introduced during the flash process.
