Hello Flebourse,
checked your command but nothing changed.
I also did a test , to put the simcard into my cell phone and it worked immediately fine. I get an IPv6 (and IPv4) and i can access the internet without any problems. IP test in the Browser shows also the IPv6 (and IPv4).
I have problems to understand what happens technically in the router.
Again, i get an ipv6, which is visible in the network interface, if you log into the router. But whenever i do an ip test (in a browser) it does not show the ipv6 and access the internet via ipv4. For ipv6 only use case it does not access the internet at all.
Is there maybe something in my Windows Firewall i have to enable/disable?
Or do i have to modify my network settings?
Best regards
