Internet connectivity issues since upgrading to gigabit service

I recently upgraded to the xfinity gigbit service and have been experiencing consistent connectivity issues thorughout the day ever since. This is particularly painful when on Zoom meetings. I've worked with Xfinity support three times now. Each time they did the usual modem reset, signal check, factory reset, etc...  A technician came to the house to check the signal and didn't detect any issues. I've removed all splitters from the line and generally see healthy stats (SNR, power) on the modem. However, the issues persist and happen regularly throughout the day, everyday.

 

One thing I have noticed is when the issues happen, they consistently align with "MDD message timeout" messages in the modem logs. And often I also see a short dip in the SNR numbers.

 

The following is my modem when things are healthy:

Finally, the following is a snashot of my logs which show the "MDD message timeout" messages whcih correlate directly to the issues:

My modem is a Netgear CM1100 running firmware version V6.01.07.

 

This is extremely frustrating and support has not been helpful despite ensuring me it will be escalated and addressed. I see that others have experienced similar issues on these forums but I haven't seen a specific solution. Any help would be appreciated!

Thanks!
