Started Unicast Maintenance Ranging - No Response received - T3 time-out - (internet drops)

Hi,

started about 5 days ago,  seems to be similar to others; I have between 2-6 outages daily now (lasting 1-3 minutes each), all with that message following in the modem log.  Power levels seem to be fine, all cable connections are tight. Just moved in (new construction) 4 months ago, and all was fine until now...?

 

Where do I 'go' for help?  

 

Modem is CM1200 (Have GIg speed down, 50Mb up)
