Default Constant connection drops/ internet outage

I have been having the same problems

I have the same issues as well. My internet drops at least once a day every day. Today it's been out off and on throughout the day. Spent about an hour and a half on the line with Comcast being transferred from one tech person to the next, including their "Motorola modem" experts with no one having heard of this issue, despite a quick google search revealing it to be a common problem.

I've read a lot of forums and looks like the error log above is pretty common. Unfortunately most of the diagnostic and resolution comments on the forums are above my technical know how or understanding.
