Let’s see what’s inside
Activate easier with the app
Take the fast lane
The Xfinity xFi app will walk you through activation and be your go-to destination for managing your home network moving forward. Download for free on the App Store or Google Play. Can’t get the app right now? Skip down to “Activate using this guide”.
Activate using this guide
1. Place your Gateway
First, choose a central location near a cable outlet for your Gateway, and take note of your network name (SSID) and password located on the bottom of your Gateway.
Place your xFi Advanced Gateway at least 3 feet from the ground, avoiding cramped spaces or anything that may block your WiFi signal.
2. Plug in
Connect your coax cable and power cord to your xFi Advanced Gateway. Then,
connect your coax cable to the cable outlet and plug your power cord into an
electrical outlet without a dimmer or wall switch.
For Xfinity Voice customers, connect your telephone to the Tel 1 connection on
your Gateway using a telephone cord (not included).
Your Gateway may take up to 20 minutes to boot up-don’t unplug it. The LED light on the top of your Gateway will blink green and yellow. Wait until this light remains solid white for 60 seconds, then you’re ready to move on.
3. Connect
Access the WiFi settings on your personal device. Then, select the Network
Name (SSID) from your Gateway noted in Stepl and join using the password from
Step 1.
If you’re asked to enter a Pl N, select “Connect Using a Security Key” and
enter the same password from Step 1.
Connect with Ethernet
If you do not have a Wi Fi-capable device or if you prefer an Ethernet
connection, plug one end of the provided Ethernet cable into an Ethernet port
on your Gateway and the other end into the port on your computer. If this
worked, the LEDs next to the Ethernet ports on your Gateway will light up.
4. Activate
Once connected, if you’re not automatically directed to a setup screen, open a
web browser and go to register.xfinity.com. Follow the steps to verify your
account and set up your WiFi network. After setup is complete, go to WiFi
settings on your device, wait to see your personalized WiFi name listed and
join using your password (you can skip this step if you connected with
Ethernet).
If you’re using a Battery Backup, refer to the steps in that guide once your
Gateway is activated.
