CM1000V2 DS light flashing but internet connection is great

Problem solved. Replace the section of coax in the attic. The connectors were installed poorly. Used a quality quad shied rg6 and compression connectors.

Thank you for the suggestions. I’ll check the connection at the outside box. I’ve also looked at the line between the outside box and the wall socket for my modem. There a section that was added to extend the cable from the family to living room. It has been working fine for 20 years, but I plan on replacing it. After all the work on my end is completed, I’ll push more on Comcast.
All the more reason to check it carefully and/or have it replaced!
