What is the right firmware version for the CM1100 on Xfinity/Comcast?

According to the following page, the right firmware version for CM1100 and Xfinity/Comcast is V2.01.02:

However, on my CM1100 I am seeing the Firmware version as V6.01.07.

What is the right version? I ask because I've been experiencing connectivity issues and I want to cover all bases.

FW will come from your ISP only. So theres no right FW version. 

Check the following:

Have the ISP check the signal and line quality UP to the modem. 
Be sure there are not 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.

Yeah, understood that the firmware comes form the ISP. However, the Netgear article states V2.01.02 is the current firmware that Comcast delivers for CM1100. This does not match what I am getting for my modem, which is v6.01.07. So either the Netgear KB article is wrong and should be updated or Comcast is delivering the wrong firmware to my modem.

ISPs can and do update modem FW as well. So regardless of the information on NG site, maybe out of date or inaccurate. 
Is the modem working? Of so, then you'll be fine.

Thanks @FURRYe38, makes sense.

Things are actually not working well. I've been having consistent connectivity issues since upgrading to Xfinity Gigabit and the Netgear CM1100 modem. We've been going through a process of troubleshooting this. It appears we have short connectivity issues that correlate to "MDD message timeout" warnings in the logs. These warnings are in the logs throughout the day and can cause more significant issues when clustered closer together in time. Typically this manifests in buffering video or choppy Zoom conferences.

To date we've replaced all lines and connections from the pole to the house, removed all splitters and verified that power and SNR ratios are generally good.

So, I'm still at a loss for the cause of the MDD message timeouts and why this may cause connectivity issues. The firmware question was grasping at straws. One other oddity in the Netgear CM1100 logs is they appear to be off by an hour, not sure if this could cause a problem.

Any guidance or tips ere would be helpful.

Thanks!
