Hello, @user_d5wvmp thank you for reaching out over Xfinity Forums. Working from home myself, I completely understand the importance of having your home network running properly.

I'd definitely like to continue investigating and appreciate the equipment information, and see the CM2000 is on the certified modem list:

I know you had mentioned some previous maintenance work, have you checked the helpful status center:

https://www.xfinity.com/support/status or Xfinity App to see if there are any reported issues or run self-help troubleshooting to see if the system can detect any concerns? 

We also have this great post that can be referrenced for some great tips, as well as see what the equipment signal levels are supposed to be, and how you can check your equipment signal levels to compate: https://forums.xfinity.com/conversations/your-home-network/internet-troubleshooting-tips/602dae4ac5375f08cde52ea0

- Have you happened to have checked your signal levels to see if the upstream or downstream are within the proper range?
