So, when ipv6 works fine : in my router ipv6 WAN settings, it shows, i am getting ipv6 , as well as sites like https://whatismyipaddress.com/ shows I have ipv6 too. Also in https://test-ipv6.com/

But, everytime I turn off my router at night, and turn it on in the morning again, sites like https://whatismyipaddress.com/ shows ,no ipv6 detected.

But, in my router ipv6 WAN settings, it shows ipv6 is connected:

And i checked from my phone and other devices too, no ipv6 showing in site https://whatismyipaddress.com/ ,also in https://test-ipv6.com/

Then, when I hit disconnect and connect in ipv6 LAN settings couple of times,

sites like https://whatismyipaddress.com/ starts to show that I am getting ipv6 again.

So, I have to follow this connect and disconnect thing everytime I turn off and turn on my router to get my ipv6 connection.

1. What could be the possible reason my router behaving like this with ipv6?

2. Is it possible that my ISP has any problem from their side?

3. Is it possible that you will provide firmware updates soon for this router which maybe able to solve this issue?
