DPC 3825 Error Log

I am still having major issues with my Internet dropping and I got a new DPC 3825 Gateway but where are the error logs so I can see what the heck is happenning.  I have no splitter and the cable is a straight shot and this has been happenning since Cox upgraded there system to the Docsis 3.0 last year so don't tell me it is my equipment.  I never had this issue before they changed there's so the fault is most likely in their equipment.  It also happens randomly as well no set time.

I would like to get the speed I pay for also.

These are the only logs I could find as well.
