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 hou r and a half on the line with Comcast being transferred from one tech perso n 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 com mon problem.

I've read a lot of forums and looks like the error log above is pretty comm > Time Priority Description
