Wireless Gateway: CGM4140COM
I just traded my old gateway for this gateway.
I consider myself good at computer tech.
But, I have been having problems setting up this gateway.
First, it wants me to connect to the internet.
How am I going to do this, as my gateway is not set up?
Then I found out trying to login into my account using my cellphone that after going to the Xfinity store my password has changed.
I had to go to all the hoops to set a new password.
I downloaded the app they said I need to set the gateway up.
The app comes up to a blank white screen.
After using my internet settings, I was able to connect to the XFINITY network.
Where do I go from here to set up the gateway?

I just got the app on my iPad and I got to the screen that has the button to sign in.
when I" click on it I get the window with 3 large dots.
After a while, I get an error message and try again button.
I have hit that button 10 times and keep getting the same message.
I think the 802.1X is causing the problem. You can't turn it off.
I could not switch the iPad from XFINITY to my iPhone's hot spot.
I switched to using my iPhone using cell data.
On the phone I opened the Xfinity app.
It took a long while waiting for each segment to complete.
I have it running now and changed the network name and password.
My iMac is now connected to the new network.
My next question is going to be "Can I set the Wireless Gateway: CGM4140COM to use WPA2/WPA3 instead of WPA/WPA2?"

Documentation / Setup / Test may not be a strong suite for Comcast.
The Wireless Gateway 2 (model number DPC3939) and the Wireless Gateway 3 (models DPC3941T, TC8717* and TG1682G) offer the functionality of a WiFi router, DOCSIS 3.0 cable modem and voice modem in a single device. If you have both Xfinity Voice and Xfinity Internet service, the Wireless Gateway 2 and Wireless Gateway 3 devices both provide an all-in-one way to stay connected and manage your home network.
