Find out how you can activate your Xfinity Internet and Voice services with an Xfinity Gateway or an approved owned (third-party) device.

Activate with an Xfinity Gateway

1. Download the Xfinity app.
   • Create your Xfinity ID and password.
   • Log in. 
2. Identify your device. 
   
   • Look for the QR code on the bottom or side of your Xfinity Gateway.
     • Focus on the QR code with your smartphone’s camera.
     • When it has been scanned, you'll see a green checkmark.
   • You can also manually enter your gateway’s CM MAC Number or SSID number. 
3. Place your gateway or modem.
   • Find the cable outlet most centrally located in your home.
   • Place your gateway or modem in an open area away from exterior walls, metal surfaces, microwaves and windows.
     
     • Don't place it on the floor.
     • Avoid cramped spaces and anything that can block the device signal.
4. Connect your gateway.
   
   • Screw one end of the coaxial cable into the Cable In/RF In port on your gateway or modem and the other end into the cable wall outlet.
     
     • Make sure this connection is finger-tight.
   • Plug the power cord into the back of your gateway and then into an electrical outlet. 
   • If you subscribe to Xfinity Voice service, connect your telephone to the Tel 1 connection on your gateway or modem using a telephone cord.
5. Name your WiFi network and create a password. 
6. Wait for your gateway or modem to be ready.
   • Your gateway or modem may take up to 10 minutes to be ready to activate.
   • The Xfinity app will show you your progress during this step.
   • Don't unplug your gateway or modem during this process.
   • Make sure the lights appear as described below before moving on to the next step: 
     • If you have an Xfinity Gateway with multiple lights on the front, the Power, US/DS and Online lights should remain solid for at least one minute, and the 2.4 GHz and 5 GHz lights should start blinking.
     • If you have an Xfinity Gateway with only one light on the top, it should remain solid white for at least a minute.
7. Connect all your devices. 
   
   • Once your network is set up, your Xfinity Internet and Voice services are ready to go.
   • You can connect all wireless devices, like laptops and smartphones, to your WiFi network.
   • If you replaced your Xfinity Gateway and kept the same settings during activation, your previously connected devices should automatically reconnect. 
     
     • Note: Xfinity Gateways come with a built-in Xfinity WiFi home hotspot (xfinitywifi) that may take up to 24 hours to broadcast. To learn about the hotspot, see Xfinity WiFi Home Hotspot FAQs.
