CBR750 experiencing frequent drops

Hello,

We have a CBR750 and have had frequent dropped connections since installing the device in January.  This last week, we finally got a technician to our home.  He said the connection from the box to our home was bad, so he replaced the outside line and left.  It is yet to be buried, but we still have dropped connections.  It's not consistently timed -- sometimes 2-3 times a day. A reboot of the modem fixes the issue.

Our settings look to be in the correct ranges.  I'll try to get logs from a drop later today.  Here are the current logs:
