Arris G54 modem-router can't access Xfinity IPV6

Hi,
After extensive troubleshooting with your Xfinity technical support representative with no fix, I was advised to contact Arris, the manufacturer of my G54 modem-router, for further assistance.

So, I did, and Arris support confirmed that my device is IPv6-capable and compatible with Xfinity.
Could you please reprovision my Arris G54 for IPv6?

  • MAC address: You should have this information. However, if you don't, send me an email or text 
    Currently, my connection is IPv4 only—no IPv6 prefix delegation is being sent.
  • To enable IPv6, please push dual-stack IPv6 with /64 prefix delegation.
    Thank you for your help

It seems as if IPv6 nonconnectivity with Xfinity is an issue for many. I see many of the discussion areas on this topic closed.

When can I expect from tech suport to get IPv6 working for me?
