Re: ipV6 disconnecting

What Firmware version is currently loaded?
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. CAT6A STP is recommended.
Using the Multi Gig port or Yellow Internet port for the connection to the ISP modem/ONT?
What IPv6 setting are you using? DHCP? AUTO? Static? 6To4?
Try using a custom IPv6 DNS configuration on the router, i.e. Cloudfare, Quad9 or Google.

When you unplug the router for about 30 seconds and plug it back in, everything is back to normal. That is, for a few more days and you have to repeat the procedure in order to get IPV6 back. Clearly this is not an ISP issue, otherwise you could reboot the router many times and not get IPV6.
Is this a known issue or is there something weird going on here?
Thanks for replying.
I'm using the latest firmware, i.e., V1.2.13.100_2.0.54. My ISP is Google Fiber. Their fiber jack is on the wall, I don't know it's model number. It works OK.
I'm using a Cat6 cable. Google says I can get away with Cat 5E. It's on the WAN port. connected directly to the fiber jack. They promise 1000-Mbps up and down. When check with LAN I consistently get 945-Mbps up/down, so they deliver.
Router settings for IPV6 are set to auto-config. In my experience no other setting works. I have Cloudflare's DNS servers on the router for both IPV4 and IPV6. They work great and are very fast.
When IPV6 disappears in it's all my devices. So far it's been 48 hours since my last reboot and IPV6 is still there.
Ok. Might save off a back up config to file for safe keeping. Saves time if a reset is needed.

There is some type of electronic device between the end of the fiber optic cable and the Ethernet connection to your router. What is the name brand and model number of this device? Look on the label. You might have to look for the device first. You just think it is working OK. What does your ISP say about their support for IPv6?
When you change the IPv6 setting to something other than auto-config, do you restart both your optical network terminal (ONT) and your router?
Just because Cloutdlare's DNS servers are fast in your area does not mean they are stable over the long term.
