So all is working with GN enabled now?

I re-enabled the Guest network and a few minutes later my 2.4 and 5G networks stopped working.
Rebooted Modem and Router and it is back to normal for now...

All "appears" to be working at the moment. It's really up to my wife, who uses a Windows 10 PC (I use a Mac), to tell me when she has an issue with DNS errors. She has not been in the office this week so I should know more next week.
Let me summarize what I have for my LAN:
Modem: Netgear CM500
Router: Netgear Nighthawk X6S AC4000 R8000P Router
Netgear EAX20 AX1800 WiFi Extender
ISP Provider: Comcast.net
CM500 modem and R8000P router are located in the central portion of the house. EAX20 is Ethernet hard wired as an access point and located in my office in the back corner of the house where the R8000P does not do such a good job on coverage. EAX20 operates as a separate network with 2.4 and one 5GHz band. R8000P operates with a 2.4 and two 5GHz bands and Dynamic QoS is enabled. Smart Connect is also enabled. Also using a USB storage device plugged into R8000P. The Guest Network uses the 2.4 and one 5 GHZ channel on the R8000P. All 5 bands operate on different channels. These 5 channels were chosen using data from a WiFi sniffer showing the unused channels or channels with least interference from neighboring WiFi devices.
All DHCP duties are provided by the R8000P. DHCP starts at 192.168.1.100. I have static IP addresses set up for fixed devices such as printers, TVs etc, all located below 192.168.1.100. This way if there is an issue I know what the IP addresses are for these devices. I have reserved about 10 DHCP address above 192.168.1.100 for certain known devices using Address Reservation in the LAN setup on R8000P.

Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.
https://kb.netgear.com/24231/How-do-I-back-up-the-router-configuration-settings-on-my-Nighthawk-routerThanks, already done with saving config file.
I will post again as soon as any issues arise or if no issues I will post next week to let you know that things are working properly.
Thanks for your help,

Ok, it been a week since I enabled IPv6 and my wife has not experienced any DNS errors as before enabling IPv6 on her Windows 10 PC. Everything appears to be working normally.
So it seems that "having to enable IPv6 to alleviate DNS errors" is an issue with the R8000P firmware, otherwise IPv6 would be enabled automatically and we would not be able to disable it. I think this goes a little deeper but my limited knowledge of internet protocols won't let my fingers expound further on this issue. 😎
Thanks for all the help. It's nice to have a place to go when you are in need! I will post again if any problems arise in the future.

- Is your DNS that you are connecting your IPv6 network is also on IPv6 ?
In case not then it maybe DNS server issue and likely not IPv6 in R8000P.
However, in a perfect world if you still getting same errors then it’s likely R8000P likely be at fault Not sure what you are asking but my first sentence in last post may have been a bit confusing, should have read:

- DNS - Domain Name Service/ Server. Is often used where IP addresses are set as dynamic i.e. IP address will change upon expiration of lease time.
Most routers manufacturers have a built in feature that act as DNS server. However, third party DNS can also be used such as google, no ip etc. These server helps tracking machine based on their Domain Name regardless of IP address.
If DNS server is restricted to operate only with IPv4 then it’s likely may not be able to translate IPv6 and may result in errors.
However, I could be wrong too as IPv6 is designed to work in presence of IPv4.
That’s what I trying to understand. Let me add that before I enabled IPv6 on the R8000P router, when we got a DNS error on the Windows 10 PC, bringing up a CMD window and executing "ipconfig /flushdns" would temporarily fix the issue but the error would always show up again at a later date.
The IP address for the PC is DHCP and is served out by the R8000P router.
Since enabling IPv6 on the router there have not been any DNS errors.

Hi,
I have also been suffereing from the DNS issues since the recent firmware updates.
I have enabled IPv6 using Auto Detect and it has changed to 6to4 Tunnel.
I am in the UK and my ISP is Virgin Media.
Is this OK?
- Well I can only vouch for R8000P router. The Autodetect is setup as DHCP which makes sense. Unless you are creating 6to4 Tunnel with another host.
It might be different for other routers. - Just wanted to add that 6to4 tunnel is used to combine IPv4 host network and IPv6 host network. By means of 6to4 Relay router.
I am using R8000P, and it appears to be working with my Windows 10 PC and Tablet, but our android phones are acting up.
Ignore me, I had left our android phones on Static IP and DNS, reverting back to DHCP and it is working fine now
Been watching this thread. I'll try 1.4.3.88 in 2 days. Will be refreshing if the DNS issues is finally resolved.
I recommend enabling IPv6 if DNS issues are seen.
Greetings,
Its already on, for years. I've been testing each few FW releases since 1.4.1.68. All have exhibited the DNS error with or without reset, starting from scratch or having IPv6 enabled, etc. I'm WFH tomorrow and will try 1.4.3.88, then report back.
👍
Seems to work for some, others maybe not so much. May depend on configuration or ISP configuration as well.
I know I ran my R7960P with v88 loaded and saw DNS issues. Enabled IPv6 and DNS issues did not re-appear.
