Xfinity Router/Modem Combo SEVERE loss in range
Recently, my router only extends about 20 feet in connection range, where as before, all devices in the home could connect from any room. I can stand by the router, connect, walk up the stairs (max 20 feet) and the connection will be lost. As soon as I go back down the stairs, I can connect again. The internet is working, and when I am connected I have no issues. Any guesses for why this happened so randomly? I didn’t change anything to the location/wiring/package.

For anyone else having the same problem, I resolved it by exchanging my router/modem combo with Xfinity for a new one. It has fixed it!

If it's an apartment/townhouse situation where neighbors are close and everyone is using the same Xfinity equipment, you've got no control over the radios with their crippled gear. You can get a free WiFi scanner like acrylic home wifi or use iwlist (linux) and see how many radios are broadcasting around you. It will tell you a potential problem.
You could try to move the gateway for a temporary test. Even 10 feet can help if it's on top of an interference source. It could be another type of device entirely, appliance, speaker, etc that turns on intermittently if that is the problem.
You might be able to change WiFi standards still on your Xfinity equipment. Instead of 802.11ac, you could try to set it to broadcast 5G and 2.4G. 2.4G will be the slowest (11Mb/s tops) but it works better with walls and distance. Set unique broadcast SSID's for them. They disabled the local interface, but you may be able to still do this with the phone app depending on your hardware and the firmware they pushed to it: https://www.xfinity.com/support/articles/change-wifi-mode-admin-tool-xfinity-xfi Some here say that doesn't work anymore, but you could look for the option.
Other 3rd party equipment can give you more control over the radios.
