Significant packet loss between two Comcast routers

I'm seeing significant packet loss (up to 20%) on certain connections.  I think I've isolated the problem to the link between two specific Comcast network devices, but I'd appreciate if a Comcast employee would check over my conclusion.

Hello @asdorsey12! Thank you for taking the time to reach out and being part of the Xfinity family. I'm sorry you've been having so many issues with your internet. That's definitely not the experience we want you to have. I'd also be frustrated if my internet services weren't working properly. Especially now when so much needs to be done from home with a stable internet connection. I'd be happy to take a look at your account to see if I can find out what's going on. In order to get started can you please send me a private message to Xfinity Support with your full name and full address by clicking the chat icon in the top right?
