High uncorrectables on CM3000

Hello, I recently got a CM3000 modem (from SB8200) to take advantage of the new upload speeds. 

When I was looking at my modem, it seems like I have a very level of uncorrectables that seem to keep going up by the hour. I reset the modem a couple days ago, but the uncorrectables have racked up again. 

Thoughts on how to proceed here? 

I WFH so want to make sure that I have a stable internet connection at all times. 

Thank you! 

***

FYI: Modem was reset 2 days ago and the uptime is 2 days 10 hrs. 

Cable Diagnostic

Your setup looks fine. If you can't access the internet, make sure you properly activated the modem. If modem has been activated and you still can't access the internet, contact your service provider for troubleshooting help.

@ML6 Thank you for reaching out so we can make sure you have a reliable internet connection for working from home. We're a team of experts dedicated to addressing all your questions and concerns and we'll work alongside you to advocate for the best possible resolution :).

 

Let's troubleshoot to narrow down the root cause of the signal issue. Can you tighten each end of the coax connection by hand to make sure they are snug? Please check the connection at the back of the modem as well as the connection at your coax wall plate. Is there a splitter between the coax outlet and the modem?
