I hate to use NANOG for this, but support has now ended a chat with me twice without fixing anything, they just kicked me off.
I'm not getting an IPv6 address on the Comcast provided cable modem/router. I'm not getting a PD. My machines thus have no IPv6. I've hard reset my router 4 times while working with Comcast, and I've been told to do things like switch to a static IPv4 address, which shows a level of clue that is scary. And before that they were convinced it was a wireless problem even though I have a wired connection, and told them that multiple times. I've wasted two hours with Comcast today, and even when I asked for escalation I got nothing. Just hung up on. It's honestly the worst customer support I've ever received. I don't think I ever got them to understand the difference between IPv4 and IPv6.
