Frequent Modem Connection Resets

Hello,

 

I have a Fido 150u plan and I am experiencing severe modem (Hitron CODA - the white box) issues where the connection drops every single day. About 5 days ago, a licensed service technician arrived and possibly improve the connection qualities by replacing some connectors and removing splitters. However, the connection resets (as indicated by LED on my Hitron CODA modem) still occurs today. I am replacing the hardware modem and looking forward to the next level of troubleshooting. 

 

These are my logs - (The CM MAC has been masked but not the CMTS MAC). I am concerned with the "REG-RSP-MP Mismatch" and the NTP time sync is also questionable.
