Lots of T3 errors, MDD message timeouts etc.

3 year old Netgear C6250 modem/router combo directly connected to the entrance to the house (no splitters anywhere, brand new copper clad cable).  Have tried all resets/power cycles/ unhooking the cables and checking for issues etc.  I am getting lots of short dissconnects throughout the day and my logs look like this below.  Also have the upstream and downstream info below as well.  Comcast says everything looks good on their end.  Could this be a modem going bad? Or something outside the house causing issues? The service is all just installed to a new house build 3 years ago.  Thanks in advance for any help.
