Activate Xfi Gateway Using Xfinity App

Posted on  by admin


Activating an xFi Gateway or an approved modem/router is simple with the Xfinity app (download at the App Store or Google Play). The xFi Fiber Gateway (Arris X5001) is only available through professional installation and can't be activated using the Xfinity app. To see which model you have, look on the bottom of your Gateway.
If you're not prompted to activate after signing into the Xfinity app, you can navigate to the activation entry point by selecting the Account icon from the top-left corner of the Overview tab on the Xfinity app and then selecting Activate xFi Gateway or Modem under the Devices section. Also, see Activating an xFi Gateway with the Xfinity app or Activating Your Own Modem Using the Xfinity app for more details.

Ultimate control with the Xfinity app

If you’re activating Xfinity Voice service without Xfinity Internet, activating a pre-installed Xfinity Gateway in your WiFi Ready apartment, or your mobile device does not support the Xfinity app, you can use the steps below:
Note: These steps apply to both Xfinity equipment and approved owned equipment. We recommend that you also consult your manufacturer’s installation guide for instructions.
  1. I just received my self installation kit and I’m trying to set up my service and I was wondering if there is a way to activate the xfi gateway without using the app. The app on my phone is unable to find the device and I’m thinking it is due to my phone being old having trouble connecting to WiFi at my previous residence.
  2. Every step of the way. And now you can get the most out of your home network and the xFi Gateway with the Xfinity app, the single destination giving you access to our latest tools and features. With the xFi Gateway; and download of the Xfinity app, you can:. Easily monitor and manage your home WiFi network. Get notifications about activities on the home network. Create your own WiFi name and password profiles for all the members of your household.
  3. To activate the Xfinity App on your mobile device, simply download the app on the Apple App Store or Google Play Store and enter your Xfinity credentials to log in. The power of one app to handle them all is now in your hands.
  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.
