Sorry, I did not get a notification of your reply.  I agree with ALL your comments.  It's exactly what I have told Comcast but they don't seem to be able to escalate it to anyone that can assist.  I just created another post with screeshots of the signal changes.   https://forums.xfinity.com/t5/Your-Home-Network/Motorola-MB8600-locks-up-almost-daily/m-p/3193788   Please let me know if you can help push this in anyway.  Thanks ...
