ANSWERED: How to Self Install and Activate Your Internet Equipment

This article guides you through the steps to self-install and activate your Internet equipment. It covers both Xfinity Gateways and third-party modems or routers.

If you are replacing a device already installed in your home, be sure to disconnect that device before continuing.

Ways to Activate Your Internet Equipment

All Self-Install Kits include installation and activation information. You can find this in your Xfinity folder.
  • Activate Your Equipment Using the xFi App
  • Activate Your Equipment Online
  • Activating a Different Gateway or Third-Party Modem/Router




Activate Your Equipment Using an App

If you’re activating Xfinity xFi Pods or an Xfinity xFi Gateway (with the exception of the xFi Fiber Gateway, Arris X5001), you can use the Xfinity xFi app for easy activation. After setup, you can use the app for management of your home network. To determine the type of Gateway you have, check the make and model information located on the bottom of your device. You can also sign in to My Account and select Devices.

  1. Download the Xfinity xFi app for free from Google Play or the App Store.
  2. Sign in using your Xfinity ID and password.
    • If you don’t have one, you can create one from the sign-in page.
  3. Once you are signed in, follow the on-screen prompts for easy activation.
    • If you are activating xFi Pods, go to More > Xfinity Device > xFi Pods.
    • If you are activating an xFi Gateway and aren’t automatically prompted to activate, go to More > Xfinity Device and choose either xFi Gateway or xFi Pods.



Activate Your Equipment Online

If you’re activating Xfinity Internet, Voice or any TV services other than X1, you can easily activate your equipment online.

  1. Connect your Internet, Voice and/or TV equipment and turn it on.
  2. Go online to for easy step-by-step activation instructions.

Activating a Different Gateway or Third-Party Modem/Router

To activate an Xfinity Gateway or third-party modem/router that is approved for Xfinity service:

Note: These steps apply to both Xfinity equipment and approved third-party equipment. We recommend that you also consult your manufacturer’s installation guide for instructions.

  1. 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.
  2. Connect Your Gateway
    • Plug the power cord in to the back of your Gateway and then into an electrical outlet.
    • 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.
    • If you subscribe to Xfinity Voice service, connect your telephone to the Tel 1 connection on your Gateway or modem using a telephone cord.
  3. Wait for Your Gateway or Modem to be Ready
    Your Gateway or modem may take up to 10 minutes to be ready to activate. Make sure the lights appear as described below before moving on to the next step. Don't unplug your Gateway or modem during this process.
    • 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.
    • If you have a third-party model, see the manufacturer instructions to see when your modem is ready to be activated.
  4. Establish a Temporary Internet Connection
    Next, you need to establish Internet connectivity either through WiFi or an Ethernet cable.
    • Connect through WiFi (if your Gateway/modem supports a wireless connection)
      • Look for the Network Name (SSID) and Password printed on the side, back or bottom of your Gateway or modem. The name may look like Home-XXXX or XFSETUP-XXXX.
      • Go to the WiFi settings on your WiFi-enabled device and select the Network Name from the list of available networks. Enter the password when prompted. If you're prompted to enter a PIN instead of a password, click the Connect Using a Security Key link to enter the password in the Security Key field.
    • Connect through an Ethernet cable
      • Plug the Ethernet cable into one of the open ports on your Gateway or modem until it clicks. Plug the other end into the Ethernet port of your computer. The Ethernet port will light up when successfully connected.
  5. Activate Your Gateway or Modem
    Once you've established a temporary Internet connection and if don't automatically see a welcome message to begin setup, open a web browser and go to Follow the on-screen prompts to verify your Xfinity account and complete the activation process.
    Note: When you've finished activation, your Gateway or modem may reboot, and it may take up to 10 minutes before you can connect to your home network.
  6. Connect to Your Home Network
    After activation, connect your devices to your WiFi name and password for your home network, if your Gateway or modem supports a wireless connection. If you replaced your Xfinity Gateway and kept the same settings during activation, your previously connected devices should automatically reconnect.
    • Go to the WiFi settings on your WiFi-enabled devices. Once you see your WiFi name appear in a list of available networks, you can connect your devices to your home network.
    • Select your home network WiFi name and connect with the password. If you changed this during activation, be sure to use the new one that you set up.
      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 questions about the Xfinity WiFi Home Hotspot.
