Ipv6 drops after 30-1hr, comes back sometimes, have to go router ssh and flush cache, issue not resolved on the latest frimware

Use your web GUI to set defaults. After system setup using no saved files, use the web GUI to set your ISP's IPv6 parameters again. Avoid turning on anything that will use router resources such as Ai Protection, QOS, etc. If this doesn't solve the problem it could be a provider Internet issue.

Spectrum was causing me similar issues - until I switched to T-Mobile home Internet. Hasn't reoccurred a single time since the change.

My isp is blaming the router, I've told them, that the router config is fine, I even went from Asus normal frimware to Merlin, did a default factory reset, nothing best I've get it for 1hr 20 min then disappears, I do ping test to Ont modem, it fails, it would come back but idk when it does its just happens

Yeh I agree, it's on default settings, another test I did, Passthough mode, which asus call it as as Automaic ip mode, but the prefix don't come at all, so that's why I stay on native

Do you mind sharing the service provider? I am still using Tunnel 6to4 for Frontier here in Southern California. In my parents' home with AT&T Fiber I use Native....

What is the result from https://test-ipv6.com/

Sounds familiar. Spectrum always said the problem was on my end - two GT-BE98 Pros and one BE96U. The problem doesn't exist with T-Mobile service. Every IPv6 test always completes perfectly now and all IPv6 only sites are always available for access. Your ISP likely doesn't have its own IPv6 servers and uses some method of providing it on IPv4.

I'm afraid the ASUS IPv6 instructions might be mistaken. It is really up to the ISP which implementation they choose. On AT&T Fiber IPv4 is Automatic, yet the required gateway clearly has Native for IPv6.

For Frontier I contacted technical support, which is also IPv4 Automatic from their ONT, and they say IPv6 is available, BUT I have to use their eero router to enable it. I try Native and nothing, Passthrough and not really working either. I try Tunnel 6rd and nope, yet Tunnel 6to4 gets 7/10 on the IPv6 test site with a Prefix of /48. (AT&T is /64, and some claim it is a challenge to create IPv6 VLANs)....
