Download the Xfinity App to Get Started

The Xfinity app is the easiest way to activate, manage, and troubleshoot your Xfinity service. You can also pay your bill, view plan details, get outage updates, and more all from your phone.

​

Download the free Xfinity app from your device’s app store or scan the QR code included in your materials to get started with your Xfinity Wi-Fi Setup.

Before You Start, Make Sure You:

  • Have your Xfinity ID and password ready (Primary, Manager, or Member accounts only).

  • Find an active cable outlet in your home (usually in a living room or office).

​

If you live in a WiFi Ready Apartment with a pre-installed Xfinity Gateway, the hardware will already be connected.

Xfinity Internet Self Installation and WiFi Setup:

Step 1: Open the Xfinity App

  • Launch the app or scan the QR code to sign in.
     

  • Select Get Started to begin activation.
    (If replacing an existing gateway, go to Account > Devices > Activate xFi Gateway or Modem.)

​

Step 2: Set Up Your Gateway

  • Connect your gateway to the active cable outlet with the coaxial cable (finger-tight).

  • Plug in the power cord.

  • Wait for the lights:

    • Single-light models: Ready when the light turns white (solid or blinking).

    • Multi-light models: Ready when the top three lights are solid.

​

Step 3: Check Your Connection

  • In the app, select Check Connection to confirm the outlet is active.

  • If the outlet isn’t active, select Try Another Outlet or I Don’t Have Another Outlet to schedule a technician visit.

​

Step 4: Personalize Your WiFi

  • Choose a WiFi name and password you’ll remember.

  • Confirm your information. (If upgrading from a previous Xfinity Gateway, you can keep your existing network settings.)

​

Step 5: Complete Activation

  • The activation process can take up to 10 minutes.

  • Enable push notifications to be alerted when setup is complete.

  • Once activated, connect your device to the new network:

    • Auto-connect if prompted.

    • Manual connect: Copy your password, go to device WiFi settings, and join the new network.

After Setup:

Once your gateway is active, the Xfinity app lets you:

  • View and manage your network settings.

  • See who’s connected to your network.

  • Pause devices and block content.

  • Troubleshoot any connection issues.
