Xfinity Internet Dropping Regularly

Hello,

I am not sure where to turn at this point. I recently switched to Xfinity Internet as a new customer about 6 months ago. The first two months or so, I was satisfied with our internet availability and speed. Consistently over the past several months, our internet has dropped constantly without rhyme or reason (well I'm sure there's a reason, that's why I am here looking for help). We will incur an outage for approximately 3-5 minutes at a time, and this happens about 15-20 times a day (on a good day)

My wife works from home and the frequent and constant internet disruptions are now resulting in her getting disciplined at work; she now uses her phone hotspot in fear of internet drops which is completely unacceptable. 

When we switched to Xfinity, a new coaxial line was run from the pole to our house, and the tech used our existing coax line going from outside the house to inside. 

Equipment: 

Xfinity Modem, XB7 functioning in Bridge mode

UDM Pro running UniFi OS 4.2.12

Steps taken:

  • Rebooted the Gateway and AP
  • Rebooted Xfinity XB7
  • Reseated uplink cable from XB7 to the Gateway
  • Reseated coax connection from exterior to modem
  • Moved CAT6 on gateway to various ports, currently on Port3

Here are my most recent modem logs:
