Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended.
What is the brand and model of the host wifi router connected to the modem?
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no 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.
Be sure to power OFF the modem for 1 minute then back ON.

It's the name, not the model number. Model number is R6260
In house cabling and coax is the same that's been working well for several years.

Did that but will do it again.

System Up Time:01:02:13 So one basic question is - for devices plugged into the CM1150V e-net ports - does the modem act at the DHCP server or is that managed upstream somewhere controlled by xfinity? That's my guess as to where things are failing.
You should have only one Ethernet connection to your CM1050V and that is your router. Your router provides DHCP services for the devices connected to your LAN. That includes both via Wi-Fi and Ethernet connections. Your router should be configured to enable "Use Router as DHCP Server."
