Dual stack Ipv6 and ipv4 together causing failures

Question

I have a new-ish Windows 10 Creator's Updated laptop which is getting "Connection Reset" errors on some websites, such as https://xkcd.com. The connection reset errors are intermittent and not present on every website.

If I disable either the ipv4 or the ipv6 stack (doesn't matter which) the problem vanishes, and it appears to be inflicting only this computer.

What should I be looking at to troubleshoot this problem>

Some details:

• The connection is an Xfinity/Comcast cable service connection, at 200 Mbits down/12 Mbits up.
• It occurs when connected directly to the cable modem; I have ruled out other networking hardware.
• Among the devices I have to test with, only this computer (Win10 Creator's Update) is having the problem. An android smartphone and another Win10 machine running the Anniversary Update do not have this problem. Could it be a bug in the latest Win10?

Answer 1

The condition cleared up immediately after I deactivated the "Advanced Stream Detect" feature of the "Killer Control Center", which shipped with the computer.
