R8000 HAS Internet and does NOT have Internet at the same time
Any thoughts why this may happen with X6 AC3200 WiFi Router (R8000) On one hand, almost all connected Wi-Fi devices drop Wi-Fi or claim "no Internet"; Anveo monitoring service says "SIP offline". ...
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.
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...
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...
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.
FURRYe38 , setting the R8000 to AP mode is not an option for me, because I use Circle on Netgear.
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.
