Installing new modem without WiFi
I will be receiving a new modem soon, to replace my existing one. I intend to use the Xfinity app to install it. When I power off my router and lose the WiFi will I be able to use the cellular signal to complete the install? - or will I have to connect the modem to my laptop?

Great question, your smart phone would run off your data plan when its not connected the Wi-Fi, you can also see about using our awesome xfinity hot spots for a Wi-Fi connection, download our amazing xfinity Wi-Fi hotpot locator app to find the nearest Wi-Fi hotspot.

I've done this several times; you should do all of the provisioning in the app with your phone on the cellular network. Don't even connect to WiFi until you're done with the setup process.

When you get the new one, hook up the coax and plug it in. Wait a while for it to fully connect.
On the sticker on the new one, there is likely a "default wifi key" you can use to connect to the device with WiFi. You'll need the MAC address and CM MAC on that sticker too when you activate, so write those down too.
Is the app going to work then after you connect with your phone? Yeah, I dunno. If it doesn't, there is also a "captive portal". You could try activating with a web browser on your phone. Try navigating anywhere while connected to the WiFi on the new gateway. google, any website, doesn't matter. It should re-direct you to a login and activation page. It may look like it's just hanging for a while, be patient on that. That redirect may take a minute or longer. That also may or may not work with your phone's browser.
You can also try it with a PC/Laptop too. You might have better luck connected either by Ethernet or WiFi from a normal web browser with the captive browser method. If it still doesn't work, then you may be kinda stuck. Plug the old one in, and it's 1-800-comcast by phone. There used to be a direct activation number, but I don't know if it's active. They don't share it in an obvious place.
Perhaps they can activate the new ones MAC/CM-MAC while you are talking without murdering the old one immediately, then you can just swap later. Or maybe they'll have you plug the old one in, get to cell range and then try to active over the phone from somewhere else.

Their self-install device activation line: 1-855-652-3446. It still works here.
