Ipv6 and deco x60

AllMadHere85 — Sat, 05 Jul 2025 09:40:45 GMT

On my deco app it shows no information on an ipv6 connection. I can see everything on an ipv4 connection when I test my ipv6 connection it says I do not have one how can I make this work? My deco is set up as a PPPoE

How have you configured the Deco for IPv6?

BT use /56 PD

Can't lie I really don't know I have it turned on etc and followed settings in here. If I have it on PPPoe then I get no internet connection at all so I have to turn it back to dynamic.

Where it says internet connection type try PPP. If that doesn’t work try DHCP IPv6 client.

You also need to set Prefix Delegation to /56

If I change it to PPPoE it cuts my internet completely off

I assume you have the Deco X60 running as a router, plugged into a router from BT. If you are happy with the services provided by the BT router and just want to use the Deco for WiFi, then you may be able to set up the Deco, as just a Mesh system. If you "double NAT" the Deco, so it's running as a router behind the BT router, I believe you'd actually need to set the IPV6 mode on the Deco to "passthru". This would mean that the BT router still allocate IPv6 addresses to your devices.

*All based on that one assumption!

I followed advice from here a few years back and have my wire straight into the deco so it acts as my router. I set it up as PPPoE. This is the settings for the ipv4

Wired directly to the ONT (or modem) Dynamic IP (sometimes called Native) should be correct. So I can't see that you are actually doing anything wrong! What is weird in your original screenshot, I would expect the router IP to be the WAN address followed by "::1".

*Just one last thought, check on your local devices to see if they have IPv6 enabled and if they are receiving an address, and don't trust some of the Check IPv6 websites! Beyond that, I'll bow out here!

On my son's pc when I searched online it's saying I have no access to ipv6. When I was in a coffee shop I tested the ipv6 and it showed my phone wasn't connected to it but it was available.

How do I set the Prefix Delegation to /56

No idea, you need to ask on a TP Link forum

@AllMadHere85

What options for Internet Connection Type do you have?

I've always Native on my Asus and that worked with BT.

On every TP-Link device I've seen (I seen quite a few), they pick up the /56 delegation from WAN DHCP. I wouldn't trust online IPv6 Checkers, one that appears at the top of my searches says my IPv6 is not functional, while others say it's fully functional.

IPvFoo is a great little extension

To check if your devices think they are using IPv6, I'd be checking in their device settings. On an Android 15/16 phone this may be Settings>About Phone>Detailed Info & Specs>Status>IP address section.

I am not sure I followed advice on here ages ago to set this up. My son's pc cannot pick up ipv6 so unsure if the online IPTV test is wrong. I messaged BT and they give me info on settings so I will try it when noone is using the WiFi. One thing I noticed is my password on ipv4 seems to have more than just BT added so I am unsure if that would be an issue too but I cannot change it right now as internet is being used.

The username is correct. It has no bearing on your IPv6 problem.

Just looking at your original screenshot again, you appear to have IPv6 connectivity.

I changed some settings and now have this. Is ipv6 better than ipv4 or does it really not matter was just assuming if it was available consoles pc etc would connect to the better one but they are always on ipv4

Re: Ipv6 and deco x60

No, IPv6 isn't 'better' than IPv4. IPv6 was introduced because the world has run out of IPv4 addresses.

There are very few IPv6 only sites at the moment so it isn't a problem if you don't have.

I did that for a long time - no BTHub, but then DV came along so I had to yield to a SH2.
