IPv6
Since replies have been turned off on all previous discussions regarding the IPv6 trouble introduced with version 7.2.7.15 and newer, I needed to create a new thread. Checking in on this once aga...

A lot of the IPv6 issues I've seen stems from DNS issues. Try enabling IPv6. But change the dns provider for both IPv4 and IPv6. See if that helps the stability with ipv6

Thanks for input, unfortunately have tried that several times in the past with no success. Went through all the usual troubleshooting steps previously.

Thanks for being patient with us. Perhaps it would be helpful to summarize the problem. i.e.

since there are no IPv6 drops
It appears that the initial IPv6 connection works for some time on the newer firmware releases, and then there is a "drop"?
(which is observed how?)
and only restarting the system restores IPv6 communication correctly until the next episode?

Exactly, it has been awhile since I was posting about the issues...if I recall IPv6 connection would drop after 5 or 6 hours and some of my devices would no longer connect. The IPv6 addresses would no longer show up in my connection stats. I would have to reboot the router to regain a connection. I checked this site to verify an IPv6 connection or not...this was all reported by me well over a year ago in other threads too that have since been locked to new replies.

FYI, straight from Cox on setting up IPv6 on Orbi:
To set up IPv6 with Cox on a Netgear Orbi mesh system, log in to orbilogin.com, navigate to Advanced > Advanced Setup > IPv6, and select DHCP as the internet connection type, choosing "Get Automatically from ISP". Cox uses DHCP for IPv6, requiring no special login or static address settings.Step-by-Step SetupAccess Settings: Open a browser, go to orbilogin.com or orbilogin.net and log in to the main Orbi router.Navigate: Go to Advanced -> Advanced Setup -> IPv6.Configure WAN:Internet Connection Type: Select DHCP or Auto Detect.IPv6 DNS Address: Select Get Automatically from ISP.IP Address Assignment: Select Auto Config.Configure LAN: Ensure Prefix Delegation is set to /64 (or up to /56 if needed).Apply: Click Apply to save settings and let the router reboot.Key ConsiderationsOrbi Mode: These settings only apply if your Orbi is in Router mode. If Orbi is in AP Mode, the upstream modem (like a Cox Panoramic Gateway) manages IPv6.Modem Requirements: Ensure you have a DOCSIS 3.0 or 3.1 modem to support IPv6.Verification: Visit a site like test-ipv6.com to confirm your connectivity.Troubleshooting: If connections are slow, try setting IPv6 DNS to use Google DNS (2001:4860:4860::8888 / 8844) or Cloudflare (2606:4700:4700::1111) if auto-configuration fails to provide speed.
Have tried multiple dns servers, currently using Cloudflare for IPv4 and 6
