CM1200 Modem Dropping Connection

So today I took the CM1200 back to Best Buy and told them we've checked everything and the RCN tech even made connection replacements on the cable and sees everything running perfect on their side, but the modem continued to have Internet dropping issues. I told them that after talking with RCN, we figured that if it continued dropping after they made sure everything was fine on the network side, it would HAVE to be equipment issues so I wanted to replace it.

Best Buy swapped it out for another CM1200 and I installed that today about 3:30pm ET.  About 10mins ago (10:10pm or so) the new one did the SAME thing. Internet dropped, the download light was flashing again and I had to reboot to get it back up and running.  SAME problem. Checking the logs it showed same errors as previously shown in posts above.

I can't believe I had two bad modems.  I got them from two different Best Buy stores, not that that makes a difference, but it could. I guess there's a possibility of me getting two bad ones but the odds have to be astronomical.  I fully believe there's a config issue of some sort, quite possibly the firmware. Right now the modem shows Firmware version V2.02.05 which I think is the latest. If I had to bet money, this is the issue. So this begs the question, how do I get the modem on a different version to test it out?  Is this driven by the ISP RCN?

Again, appreciate the help as I continue trying to troubleshoot this problem. I don't want to give up on the Netgear Modem....I've had good luck with all of my Netgear equipment over the years and I want to exhaust every effort before I throw in the towel.
