I need some help with IPv6 configuration on TP Link router

[akirwin]

The fttc connection went online 14 days and I decided to use HG612 3B modem with TP Link the specific model is  the BE9300 Tri-Band Wi-Fi 7 Router Everything is fine with ipv4 configuration, the only problem I want to solve is the Ipv6.

...But you don't say what the problem actually is?

Assuming it's not getting an IPv6 address at all, it would suggest you need to set the TP-Link on "Native IPv6" or "PPP Ipv6".

It won't work fails to connect IPv6 settings are the following 

IPv6 enabled 

PPoE 

Share ipv4 session 

Get IPv6 is auto

Prefix delegation: enabled

DNS : set to cloudfare

[WSH]

I'm not particularly familiar with this TP-Link model myself but I seem to recall another post were it was the share IPv4 session that was causing the problem.

This wasn't solution for me IPv6 started working after I tried adding the password to the IPv4 session.
