CM500 Modem Connection Drops & Error Logs

Over the past several weeks, I've experienced an increasing frequency of internet connection drops.  While some are short (10-30 secs.) and will reconnect without powering the modem and router down and back up, other drops do not reconnect and require power cycling the hardware.  When I called my ISP (Spectrum), they did not see any errors and simply refreshed the signal to my location.  Otherwise, my ISP indicated that my line connection looks good and I should contact Netgear about the modem.  While my modem is only 13 months old, it is unfortunately out of warranty, and I cannot decipher the connection and event logs.  Based on the information from my modem's logs, can anyone see any issues with the modem or potentially the connection with my ISP?  Thanks.

Got lots of T3 Criticals in the logs. Something the ISP should look at as well. 

Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box. 
Be sure your using good quality RG6 coax cable up to the modem. 
Be sure to power OFF the modem for 1 minute them back ON.
