Hope this may help as I use Xfinity and have an Archer C8, but I found I needed to power cycle the router between changes to the router settings in order to get IPv6 to connect. It took several different combinations before I found the one that works for me. I used https://test-ipv6.com/ to determine if I got an IPv6 connection. I recommend you back up your current settings first in case things get messed up, plus it is always good to have a good backup.

@gnad 

 

What do you mean by 'did not work'?

 

On Windows? Open a CMD prompt and enter IPCONFIG /ALL. Do you see IPv6 addresses?

 

Partial of my IPCONFIG output:

 

==========

 Default Gateway . . . . . . . . . : fe80::52d4:f7ff:fe68:
                                     192.168.0.1
 DHCP Server . . . . . . . . . . . : 192.168.0.1
 DHCPv6 IAID . . . . . . . . . . . : 612384605
 DHCPv6 Client DUID. . . . . . . . : 00-01-00-01-1D-04-98-
 DNS Servers . . . . . . . . . . . : 2001:4860:4860::8888
                                     2001:4860:4860::8844
                                     192.168.0.1
                                     192.168.0.1

===========

 

I have Charter and my TP-Link Archer A20 doesn't show the DNS addresses (I use Dynamic IP (SLAAC/DHCPv6) as the type). It does show my IPv6 Address though (verified by IPCONFIG above). The 2 IPv6 DNS's above are Google's, which my A20 supplies when the ISP doesn't respond for the IPv6 DNS addresses. Spectrum/Charter uses 'Dual Stacked' IPv4 DNS's.

 

You might have the same situation with CenturyLink. One way to tell is use PING command. Like this:

 

=================

C:\>ping www.cnn.com

Pinging turner-tls.map.fastly.net [2a04:4e42::323] with 32 bytes of data:
Reply from 2a04:4e42::323: time=19ms
Reply from 2a04:4e42::323: time=19ms
Reply from 2a04:4e42::323: time=20ms
Reply from 2a04:4e42::323: time=20ms

Ping statistics for 2a04:4e42::323:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 19ms, Maximum = 20ms, Average = 19ms

=================

 

In the above, IPv6 addressing is use if there is a comparable site, like CNN uses.

@ArcherC8 ok, i will do that later, here is my test result from test-ipv6.com: http://test-ipv6.com/?ip4=174.21.104.254&ip6=2002:ae15:68fe:1:cd95:491a:3c0d:3d84&a=ok,96,4&aaaa=ok,111,6&ds=ok,92,4&ipv4=ok,169,4&ipv6=ok,160,6&v6mtu=timeout,16987&v6ns=ok,176,4&dsmtu=ok,184,4

@IrvSp when I do that, it just uses ipv4, and when I do the ipv6 address, it times out. I will power cycle the router as suggested by @ArcherC8

@gnad 

 

From your link, you appear to have an IPv6 IP WAN Address:

 

================

Your IPv6 address on the public Internet appears to be 2002:ae15:68fe:1:cd95:491a:3c0d:3d84
Your IPv6 service appears to be: 6to4

================

 

Also there appears to be an ISP problem with LARGE Packets:

 

================

Test with IPv4 DNS record  
ok (0.096s) using ipv4
Test with IPv6 DNS record  
ok (0.111s) using ipv6 6to4 
Test with Dual Stack DNS record  
ok (0.092s) using ipv4
Test for Dual Stack DNS and large packet  
ok (0.184s) using ipv4
Test IPv4 without DNS  
ok (0.169s) using ipv4
Test IPv6 without DNS  
ok (0.160s) using ipv6 6to4
Test IPv6 large packet  
timeout (16.987s) using ipv6
Test if your ISP's DNS server uses IPv6  
ok (0.176s) using ipv4
Find IPv4 Service Provider  
ok (0.486s) using ipv4 ASN 209
Find IPv6 Service Provider  
ok (0.506s) using ipv6 6to4 ASN 209

=========================================

 

You are doing 'tunneling' (https://en.wikipedia.org/wiki/6to4).

 

In your Manual, https://static.tp-link.com/2020/202011/20201116/1910012697_Archer%20AX6000%201.0_UG_REV1.1.0.pdf, look at page 19, How to setup IPv6. Do you have it set to Tunneling, Page 21, step 4? If so, do step 5 on the next page. Give that a try. That is what I'm using.

I got ipv6 to work partially* with wired devices, but not with wireless devices, I think that I have to restart the router because on wired devices it gets a 7-10 from test.ipv6.com. *some websites will not work ex: test-ipv6.com

You should be getting 10/10 from the test from test.ipv6.com if all is working okay. You should see both the IPv6 and IPv4 addresses if you use https://whatismyipaddress.com/

@ArcherC8 whatismyip.com was showing my ipv4 and ipv6 addresses before, but the ipv4 address was above the ipv6 address.

@ArcherC8,

 

The above link is wrong. Should be https://ipv6-test.com/

 

In my case, I can't reach the full count, ISP part of the problem:

 

 

The Router I have, an Archer A20 doesn't allow changing the firewall for IPv6 for instance.

No, test-ipv6.com is another website that tests if you have ipv6
