Thursday
Model: Deco X20  
Hardware Version: V4
Firmware Version:

Has anyone, with Spectrum as their ISP, successfully set a Deco x20 Mesh system up for Dual Stack IPv4/IPv6?  If so what IPv6 settings should be selected?

My Deco default settings are for IPv4 only. 

I looked into setting up IPv6 and couldn't get any assistance from Spectrum tech support.  They refuse to give you any IPv6 settings for use on 3rd party routers.

I asked google what settings to use for IPv6 on Spectrum and this is what was suggested:

Connection Type:  Dyanmic

Get IPv6 Address: Auto

Prefix Delegation:  Enabled

DNS Address:  Auto

Assigned Type:  DHCPv6 first or SLAAC+ Stateless DHCP second choice.

Then, for the settings to take effect, both the Deco router and Spectrum Modem need a reboot.

 

There was also mention of Spectrum using prefix sizes of /64 or /60 or /56; preferably /60 or /56, but I have no idea where in the Deco app those are.

 

I have been misled by google in the past, so I'm hoping to find out what works for anyone that has actually done it.

 

My network works to my satisfaction as currently configured to IPv4, should I leave well enough alone, or is there something to be gained with IPv6?

Thanks for any advice.

Hi, maybe you can refer to the following posts:

IPv6 when switching to personal router

IPv6 - Prefix delegation Size

 

IPV6 is more secure and faster than IPV4 in general. It's worth a try with the following configuration:

Connection Type:  Dynamic

Get IPv6 Address: Auto

Prefix Delegation:  Enabled

DNS Address:  Auto

Assigned Type:  DHCPv6

Deco doesn't allow setting the Prefix Delegation Size. You might just need to make sure "Prefix Delegation" is enabled.

Thank you very much.

Best regards.

  @Jamval Thanks for the replies.  Initially I used the following settings:

Connection Type: Dynamic

Get IPv6 Address:  auto

Prefix Delegation: enabled

DNS Address: Auto

Assigned Type: DHCPv6

 

I rebooted and the Deco app is showing a valid IPv6 address, but test-ipv6.com is showing ipv6 address is not detected.

I think the problem is that I didn't give the Spectrum modem a chance to completely reboot with an internet connection established before I rebooted my Deco router. I have since read that if the router completes reboot before the modem reboot is complete it will result in a failed IPv6 test.  

 

So I will try rebooting again in the proper order, and if that doesn't work I will try the SLAAC+ Stateless DHCP for the Assigned Type setting.

 

Thanks again.
