Modem Errors and Random Disconnects Multiple Times per Day

I had my Netgear CM1150V (FW 4.02.02) reprovisioned last night. I am getting random disconnects and speed varies drastically - usually a modem reset clears the issue for a period (but it is hurting productivity).

 

I am seeing these errors today (MAC addresses obfuscated by me) and they correspond to drops in service.

 

The power does fluctuate on the channels but I think it is in range?

 

What are the best next steps to avoid these random disconnects multiple times per day in service?
