Can anyone help me this? I have setup a TP-Link AX1500 router to replace my Vodafone hub. I have obtained my log-in details and entered them in and it connects. I go to turn on the IPv6 setting and nothing happens. I get no IPv6 addresses. Does anyone now what the setting should be? I tried the PPoE settings and add the same log-in details, but it then disconnects and won't connect again. The dynamic IP (SLAAC/DHCPv6) does nothing. I used get IPv6 on the Vodafone hub, so I know it's enabled.
