On one hand, almost all connected Wi-Fi devices drop Wi-Fi or claim "no Internet"; Anveo monitoring service says "SIP offline".
On the other hand, router's admin screens (both via Chrome and Android app) claim that Internet is online.
Here are the details:
Occasionally, I start getting a "No internet" error when I connect to my X6 R8000. When it happens, it happens from all wireless devices at my home -- they drop connection or cannot connect, with an exception of a wireless device (work laptop) that previously established a VPN connection: it stays connected to the Internet until I manually stop the VPN.
Around the same times, I get a "SIP offline alert" email from Anveo.com monitoring service to which I am subscribed.
I can force a Wi-Fi device (such as my phone) to stay connected to the router, and then I can access the router's admin screens via Chrome at routerlogin.net and -- lo and behold! -- it claims that the Internet status is Good(!!!???). But I cannot browse Internet.
I can also access the router's admin screens via my phone's NightHawk Android app (when disabling Wi-Fi on my phone). The app shows that my router's Internet is ONLINE(!!!???). Not only that: I can test the Internet speed from the NightHawk app, and it shows close to expected speeds. Mind you, there's no Internet on all my Wi-Fi devices at that time.

I found that if I go to the "Basic Internet Setup" admin screen in Chrome and click the green "Test" button, the router reboots (I think) and then the problem disappears for a while: I regain Internet on all connected Wi-Fi devices. Also, I receive a "SIP recovered alert" email from Anveo.com monitoring service.

My R8000 has the most up to date Firmware Version 1.0.4.84.
Re: R8000 HAS Internet and does NOT have Internet at the same time
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too? Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended.
SIP ALG should be enabled by default I beieve after a factory reset.
Re: R8000 HAS Internet and does NOT have Internet at the same time
@FURRYe38 : the router is behind BGW320-500 fiber modem. The SIP is not on the modem, it's on the OBi202 device behind the router. The LAN cable cannot be a culprit, because while most Wi-Fi devices simultaneously lose the Internet, the VPN-connected device stays on the Internet. Besides, I failed to say in the OP that I am able to force a device to stay on Wi-Fi (that has no Internet) and connect via Chrome to the ISP modem's admin interface and successfully run the Internet speed test on the BGW320-500 modem.
@Kitsap : manually re-configuring from scratch gets old with Netgear routers and is the last thing I am looking forward to do. I might have to though... again...
Re: R8000 HAS Internet and does NOT have Internet at the same time
@FURRYe38 , the modem/router combo BGW320-500 is already in the "IP Passthrough / DHCP-fixed" mode, and both radios (2.4 / 5 GHz) are disabled. (This modem can't be bridged.)

I fully realize the firmware default reset is a pain. That is why you figure out how to do it with minimum effort. Once you get your device working, save a configuration backup with a file name that indicates the firmware version it was created with. Then restore with a couple of mouse clicks. Occasionally restoring from a backup brings back a problem you are trying to resolve, then you have to reconfigure from scratch.
You are wasting your time with a re-flash or firmware default reset until you track down and fully resolve the double NAT issue @FURRYe38 raised. There are different definitions for "Bridged" in combination devices. You may be forced to use the R8000 in AP mode.
@Kitsap , I don't think I might be affected by the double NAT issue. The BGW320-500 modem/router is properly put into the IP Passthrough mode as described here or here. R8000 is the only router on my network.

For testing purposes only, recommend you configure your R8000 in AP mode to see if your problem goes away. Such a test would also confirm your BGW320-500 modem configuration.
So let' say for the sake of argument that temporarily changing the R8000 into AP mode results in my problem going away. What would be the next step? I cannot stay in the AP mode without those NETGEAR features, especially Circle.

No, I do not recommend you change the configuration of your BGW320-500. Leave it alone, I do not believe that configuration is effectively disabling the router function. Configure the R8000 in AP mode and restart your network. This disables the router function in the R8000 as well as other features. If devices that connect to your R8000 Wi-Fi or via Ethernet have full and functional access to the internet, than the BGW320-500 is still functioning as a router. At the same time, check to see if other devices connected to the R8000 are losing internet access (your original problem).
Re: R8000 HAS Internet and does NOT have Internet at the same time
@Kitsap : in this old thread @FURRYe38 wrote "When [Orbi router behind the ATT gateway is] in AP mode, the ATT [gateway Arris BGW210-700] pass through needs to be disabled. Pass through is for only when the Orbi [router behind the ATT gateway] is in router mode."
Re: R8000 HAS Internet and does NOT have Internet at the same time
No, for three reasons.
No certainty how long I'd have to stay in the AP mode. Switching to AP mode for a day (or for a week) may be not enough, because the issue that I experience is intermittent and irregular: sometimes once a week, sometimes more than once a day.
No clarity what would be the next step if the issue goes away or the issue stays in the AP mode.
I don't want losing, even temporarily, NETGEAR features that are disabled in the AP mode, especially Circle Parental Controls.
