CM2000 Blinking Downstream Light/Connectivity Issues

I'm having sort of the same issue except it's my upstream that keeps blinking and connection dropping for whatever reason.  I've gone round for round with Xfinity on the connection.  They did have to fix the box in the back of my property and then run me yet another new line.  Even after all that my connection just sporadically drops whenever.  I've moved the modem to where the coax from Xfinity comes into the house to eliminate anything extra in between and yet the problem still persists.  What could be the issue?  Is it just a bad modem?  I'm including the Event logs and connection status from the modem here.  It's only just over a year old.  I can't imagine that something which costs $250 would only last just a short time.
