R6700v3 — Nighthawk AC1750 Smart WiFi Dual Band Gigabit Router DNS problem with Spectrum
DNS Problem I have an R6700v3 — Nighthawk AC1750 Smart WiFi Dual Band Gigabit Router I have an ongoing internet problem. This is randomly occurring. It’s not site specific but happens on some sig...

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.

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.

I finally solved my DNS problem with this R6700v3 router:
First, I had my ISP Spectrum come out to check my modem, which they concluded was not faulty, but replaced it anyway because it did not deliver quite the contracted speed.
Second, since the date/time in the router was still stuck (delineated below) and I was not in the mood to convert myself into a programmer to tweak someone’s code just to try getting into a hidden router firmware interface to re-set it, I replaced the router with a reasonably less expensive Netgear R6900v2 AC1900 model.
If you have any DNS or IP not found issues with this type of router, first check your date/time in ADVANCED > NTP settings. Mine displayed this on 3/5/22 and was stuck there ever since I received it from Netgear:
Current Time: Thrusday, 24 Sep 2020 14:05:29 Warning: The router failed to connect to NTP server, please check your internet connectivity or try another NTP server.
Time Zone
(GMT -08:00) Pacific Time (US & Canada): Tijuana
✔ Automatically adjust for daylight savings time
Use default NEGEAR NTP server
✔ Set your preferred NTP server
Primary NTP server: 132.163.96.5
On the onset of this problem from the time I received this router on Sep 24, 2020, the Time Zone was set on some east coast setting, which I never knew and is most likely the reason why it led to this issue.
I only discovered this disparity a few days ago as I was digging deeper into the problems I was having. I managed to get into this interface and corrected the time zone, but apparently it did not help. Kiss of death.
Some of the above settings are a result of my attempts to get an NTP connection.
Conclusions:
- The replacement router works as expected and it allows my network adapters to function both with fixed/static and with dynamic/automatic DNS addresses.
- Not willing to spend countless more hours trying to research this NTP issue further, I resolved my experience to one of two possible faults in this router:
- When the device date/time reaches a certain disparity with the NTP server date/time, the NTP server rejects any further requests. This is most likely described in one of lengthy NTP rules of engagement . The router then just posts this red text in the NTP Settings and lets you guess what is actually going on.
- Some other router defect caused the NTP updating to consistently fail, including any firmware updates that apparently totally bypass this setting.
Once the router falls into this date/time disparity mode it is a permanent kiss of death because the user has no recourse and Netgear is not much help with their support. Yes, this kind of stuff helps them sell more support and routers.
This could so easily be fixed if one actually wanted to.
