Couldn't figure out how to type in the box after pasting these logs - something glitchy about how the text field works after pasting them.
Anyway, the problem is very obvious from the firewall logs. Something related to bad handling of IPv6. This post makes it clear that it's a firmware bug that's somehow gone unresolved for 8 years. Really wanting someone to prove me wrong because I'm not in a position to buy a whole new hardware setup just to handle something that should've been resolved already. I had this problem in a different house 2-3 years ago. Comcast support was able to do nothing.
I also wanna tag @flatlander3 (does this work?), cause you seem to be the most knowledgeable on this issue as you've dug deep into it. Any advice that won't break the bank? Ideally Comcast should be reimbursing people for third party hardware.
