Correct Deco 7200 and Xfinity IP6 settings?

2022-06-27 14:21:28

Model: Deco W7200

Hardware Version: V1

Firmware Version: 1.0.4 Build 20210519 Rel. 36502

Hello,

I am attempting to get IP6 set up and working on my home W7200 mesh. I have Xfinity gigabit.

What would be the proper settings to get it to work? The default settings populate including DNS servers but testing on computers fail.

test-ipv6 says "No IPv6 address detected" but also "Your DNS server (possibly run by your ISP) appears to have IPv6 Internet access."

Thank you.

@Goldheart

Hi, the IPV6 settings are provided by ISP Xfinity directly.

Have you ever checked with Xfinity what internet connection type we should use?

Thank you.

Best regards.

@David-TP I tried Xfinity chat and technical support (which is a real PITA over the relay service - I am deaf). Both were completely clueless. Technical support had no clue what I was talking about and could not locate any information for their IP6 settings and kept telling me that I had to get this information from Deco support. What a joke. An hour and a half of my life that I will never get back.

I don't know what to do at this point since their support is clueless.

**Update: I got it to work just trying random settings.

This is what worked for me with the W7200 mesh and Xfinity:

IPv6 Connection Type: Dynamic IP

Get IP6 Address: Auto

Prefix Delegation: On

DNS servers - I used cloudflare's IP6 addresses successfully
Assigned Type: ND Proxy

test-ipv6 dot com passed with 10/10
