Re: ipV6 disconnecting
My RAXE500 keeps dropping IPV6 connectivity. After a few days when you check using whatismyipaddress.com, the site reports no ipv6 connectivity at all. If you go into the router's ipv6 settings, "Router's IPV6 Address on LAN" is empty. This is NOT the case when IPV6 is active.
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?

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.

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.
"Fiber jack" is what Google calls their modems (device between fiber optic cable and router). They installed a model GFLT300. They fully support IPV6 and keep saying the problem is on my end. This makes sense when you reboot the router and IPV6 immediately comes back. I just checked and IPV6 is active. No reboot needed at this time.
The only way to get IPV6 to work on this router is to use auto-config. All other methods don't work.
With respect to the DNS servers on the router, none are perfect. Do you recommend switching back to the ISP's servers instead? I keep hearing Google is notorious for spying on everybody. Will using Cloudflare's (or anyone else's) servers help in any way?
You can try any custom IPv6 DNS service. Try Cloudfare or Quad9 and see if the problem continues.

Does your "Fiber Jack" device have more than one Ethernet output port that would indicate a combination ONT/router type device? Does your Fiber Jack device broadcast any Wi-Fi signals?
Until you get your IPv6 issue sorted, it would not hurt to go back to the DNS servers from your ISP. When you get it working, then you can experiment with various other DNS server options.
This is a pretty good DNS test link: https://browserleaks.com/dns
If your router works with IPv6 Auto-config, it selects one of the stand alone options. Through trial and error (with reboot), should be able to figure out which one.

There is just one ethernet port on the fiber jack that connects to a router. The jack itself has no WiFi. Google offers that separately assuming you use their router. I don't like that.

No leaks. Both IPV4 and IPV6 servers show up. All Cloudflare.

In the event you're not running into this issue at all, what are your router's IPV6 settings. Maybe mine is off somewhere.
Any progress on this?
