Xr1000 V2 having DNS issues and unable to connect to websites
I just bought this router and i am having some series issues. I have updated to the latest firmware and did all the suggested things. Is anyone else having these issues and has anyone fixed it? I have a open ticket with NG. Thanks.

So six months on, this issue may have returned. Behaviour just as before - internet goes "missing" for a couple of minutes and then comes back. This started three or four days ago. Has there been another cloud update?
Firmware is xr1000v2 1.1.0.22_2.1.34
Grab the logs when it next happens and we can take a look. How often is it happening?
Does internet LED on top of the router turn RED or AMBER when this happens?
Possible ISP or DNS issue if this been working all these months then just started happening. Try different custom DNS.
By the way, while I've got some knowledgable folks available, what's the best/proper order to connect the following for both network effeciency and to prevent issues like flooding and loops, etc.?
1. Cable Modem: Xfinity XB8 with 4 gigabit ethernet ports
2. Main Router: either NetGear XR1000v2 or the TP-Link Archer C7 AC1750
3. Main Switch: NetGear GS108 8-port unmanaged switch
4. Second Switch: Generic 5-port unmanaged switch
5. Second Router: Archer AX1800
The reason for two routers is because we have extended family staying in an outbuilding (which is hardwired via a single outdoor rated CAT8 130' cable) and they have their own private network (running through my main router and assigned an IP from it), and the second switch is to "split" that CAT8 feed line to their router and my external NetGear ReadyNAS Ultra.
Thanks for your wisdom!
I see you already have a gateway router with the ISP. Your ISP Modem already has a built in router and wifi. This would be a double NAT (two router) condition which isn't recommended. This would be a double NAT condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT

Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the NG router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the NG router gets from the modem. https://kb.netgear.com/25891/DMZ-on-NETGEAR-routers

3. Or disable all wifi radios on the modem and connect the NG router to the modem, LAN to LAN configure AP mode on the NG router.

Try option #2 first...Another test to try to see if the XR router handles differently would be to configure the XR router for AP mode whlie you using the ISP gateway as a router with it's wifi disable and test for DNS issues.
Remove any other 2ndary routers from the mix as well while testing.

Thanks for your help. This issue began around the same time that I switched from using my own Arris S33 to using Xfinity's XB8, so I originally thought that the new gateway/modem was the cause. I've since ruled that out by switching back to my Arris for a few days and the issue remained.
The XB8 does have bridged mode and I have it enabled which they "claim" completely disables all routing and wi-fi functions. In fact, I even turned bridge mode off which allowed me to set the "advanced" firewall features to custom and I set everything possible to either off or fully open/unrestrictive as possible.
I also switched the XR1000v2 out with my old TP-Link Archer AC1750 for a few days and no device in the entire house experienced the issue, so I'm certain that it's something to do with the XR1000.
The XR1000 has some pretty detailed logs for like DoS attacks, etc., so why is it so difficult to at least figure out and pinpoint the exact root cause? I feel like NG should and could do that very quickly.
Try a different DNS Server. Here's a few. Also remember to change the ipv6 dns server if ipv6 is enabled.
CloudFlare
IPv4: 1.1.1.1 and 1.0.0.1
IPv6: 2606:4700:4700:0:0:0:0:1111 and 2606:4700:4700:0:0:0:0:1001
GoogleDNS
IPv4: 8.8.8.8 and 8.8.4.4
IPv6: 2001:4860:4860:0:0:0:0:8888 and 2001:4860:4860:0:0:0:0:8844I currently have it on Googles DNS. Still same issue. I contacted my ISP and they are sending me out a new modem. I do not have v6 enabled. And i did not change the pool to 100 - 200 this time around. My Firmware is 1.1.0.22_2_1_34 . It does say there is a firmware update on top but i am assuming to ignore that? The update it wants to give me is 1.1.0.16_2.1.25 .
what modem do you have?
does it work if a pc/laptop is directly connected to the modem?
It shouldn't be asking you to update if you're actually on the latest. I'm wondering if maybe you have those backwards?
