ANY FIX?

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 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
on. Unfortunately most of the diagnostic and resolution comments on the for
ums are above my technical know how or understanding.
