How to Easily Activate Your Xfinity Internet at xfinity.com/activate

Thanks for choosing Xfinity Internet! Let’s get you connected so you can start enjoying the fastest WiFi speeds around.

Activating your Xfinity Internet is a breeze. You have two simple options:

  1. Use the xfinity.com/activate website
  2. Use the Xfinity mobile app

I’ll walk you through both activation methods in this handy guide.

Activate Using the Website at xfinity.com/activate

Using the xfinity.com/activate website is easy and only takes a few minutes. Follow these steps:

Get Your Modem Ready

  • For Xfinity gateways with multiple lights on the front, wait for the Online, Power, US/DS lights to become solid for one minute. The 2.4 GHz and 5 GHz lights should blink.
  • For Xfinity gateways with a single light on top, wait for the light to become solid white for one minute.
  • For third-party modems, check the manufacturer’s instructions.

Connect Your Computer Temporarily

You’ll need a temporary internet connection to activate your service. Here are your options:

  • Ethernet cable:
    • Plug one end of the Ethernet cable into your computer.
    • Plug the other end into your gateway/modem LAN port.
    • The Ethernet port light indicates when the connection is active.
  • WiFi:
    • Locate the network name (SSID) and password printed on your modem. It will be something like Home-XXXX or XFSETUP-XXXX.
    • Select the SSID from available WiFi networks and enter the password when prompted.

Go to the Website and Activate via xfinity.com/activate

Once connected:

  1. Visit xfinity.com/activate on any internet-enabled device.
  2. Choose to verify with your Xfinity ID and password or mobile number.
  3. Follow the steps to activate your modem. This usually only takes around 2 minutes!

After activation completes, your modem may restart. It can then take 5-10 minutes to reconnect devices to your home WiFi.

Easy right? Now let’s look at…

Activate Using the Xfinity Mobile App

The Xfinity mobile app makes it super simple to activate Xfinity Internet. Just grab your phone and:

  1. Download the Xfinity app if you haven’t already.
  2. Log into the app with your Xfinity ID and password.
  3. Enable camera access when prompted.
  4. Scan the QR code printed on your modem. Alternatively, you can enter the 12-digit CM MAC address manually.
  5. Follow the on-screen prompts:
    • Place your gateway
    • Connect coaxial cable
    • Power on
    • Name your WiFi

That’s it! After confirming WiFi details, your network is ready to use. Reconnect devices to start browsing.

Additional Notes

  • Xfinity gateways have a built-in xfinitywifi hotspot enabled after 24 hours.
  • xFi Gateways and approved customer-owned modems can also be easily activated through the app.
  • The app cannot activate xFi Fiber Gateways (Arris X5001) or modems pre-installed in Xfinity WiFi Ready apartments – contact Xfinity Support in these cases.
  • To activate Xfinity Voice without internet, refer to device manufacturer instructions or contact Xfinity Support.

And there you have it – two easy ways to get your Xfinity Internet up and running! Let me know if you have any other questions.
