Internet goes down daily and requires a manual modem reset

We have Business Internet and Phone service.  Our internet goes down daily and requires us to manually pull the power from the modem to reset the internet.  The phones are unaffected.  We have a fixed IP and are using the CISCO DPC3941b modem (not the WiFi).  We've had this service for a few years with few issues, and this has started in the last couple of months.  We believe that we need a new modem.  Please advise.

We, too, are experiencing an increasing number of service outages, usually requiring a reset of the cable router. 

I am assuming that there was some erroneous router firmware update applied that is causing the exceptional number of service outages.  A reset of the router restores service temporarily, however, it is an appalling level of quality for a business internet service. 

I sent a detailed report of the most recent four outages about 10 hours ago via direct messaging as the support team always seems to request but have so far had no response.
