So there are several forums regarding people with the same issue and the issue is that my ipv6 is supported but not the ipv4. Everyone who gets this issue resolved has a Comcast guy like Comcast Phil or Comcast John direct message them and they fix it. Some please help me. I have a midterm paper due tonight and my options are limited. I have talked to multiple agents over the phone including tier 2 from Comcast and Arris but I need someone who can fix this because they couldn't. Please help.
I think it was @ComcastPhill , @ComcastJohnN or @ComcastChe that were helping. See the post https://forums.xfinity.com/t5/Your-Home-Network/No-IPv4-only-IPv6-Arris-SBG6950AC2/m-p/3128848 and respond with info requested.
