Netgear CM1100 speed and connectivity issues not getting Gig speed

I recently moved into a new townhome where Gig speed is offered.  I purchased a Netgear CM1100 that is listed as a support gig speed modem.  I have had service since 3/31/2020 and never once have I received more than 400-500mbs a second, and I experience random internet dropouts.  Things I've done to troubleshoot:

1) Factory Reset Modem

2) Tried several different Cat5e and Cat6 cables

3) Tried two different Microsoft Surface Pro 5 PC's along with a Desktop PC (all of which I have confirmed are supporting 1gbs under the ethernet adapter settings

4) I've tried connecting the modem at the wall outlet, at the feed line coming into the house, and at the feed line outside the house coming from the street

5) I've tried going through the troubleshooting on the xfinity app as well

 

Nothing has worked.  I have attached all the modem data pulled when connected at the wall outlet and the main line coming from the street outside.  I have tried going through the Xfinity chat but they are absolutely no help whatsoever.  Please someone, help me get this solved.

 

Here are the details when connecting to the main line coming in from the street

 

Here are the details from the outlet in my home

 

Here are the details showing my ethernet adapter can receive 1.0Gbps
