When you get a new Xfinity router, you must first activate it before you can use it.

It is very simple to activate your router; simply follow the steps below:

  1. Scan the QR code on the bottom or side of the router with your phone’s camera and the Xfinity app. If you are unable to scan the code, you can manually enter the 12-digit CM MAC number found on the bottom or side of the router.
  1. The app will then direct you to the best location for your router, as well as assist you in connecting the cables and powering up the router.
  1. After that, choose a name and password for your Wi-Fi network.
  1. You can now sit back and relax while the Xfinity app takes care of the rest of the setup. Once the activation is complete, the app displays your Wi-Fi name and password for confirmation, completing the setup.

After you’ve confirmed that you’ve activated your router and checked for any of the physical issues listed above, the light on your router should go from blinking to solid white. As a result, your internet connection should be stable.

However, if the lights are solid and you are experiencing network issues, here are some troubleshooting steps you can take.


The best and most common solution is to restart the router. Restarting a device generally aids in the clearing of its active and cached memory. As a result, any buggy software that may be causing problems is removed, and the device is restored to its original state.

You can manually restart your router by unplugging it from its power source, waiting 15 seconds, and then plugging it back in. You can also restart your router using the Xfinity app on your smartphone, as shown below:

  1. Open the Internet menu after logging into your Xfinity account.
  2. Select “Restart this device” from the menu that appears when you tap on your router.
  3. To confirm your decision, tap “Restart Device.”
  4. It will take 5-10 minutes for your device to restart.

If restarting your router does not solve the problem, you can try performing a factory reset. Locate the reset button on the back of the router to accomplish this.

It’s a small, recessed button that’s usually a different color than the rest of the router’s body, making it easy to spot. Gently press and hold the button with a paper clip or a pen until the lights on the front of the modem turn off. It will take a few seconds for your router to re-initialize and the lights to return to normal.

It is important to understand that a factory reset is irreversible and will erase all previous network settings and configurations, including the Wi-Fi name and password. This means you’ll have to repeat the router activation process.

An incomplete activation process could be one of the causes of the Xfinity router flashing white light. All you need to do now is finish the activation process, and the blinking white light should be fixed.

To complete the activation process, follow these steps:

  • First, get the Xfinity app for your smartphone and install it. There are iOS and Android versions available.
  • To login, enter your Xfinity ID and password. If you do not have these login credentials, you must first register before attempting to log in.
  • A QR code can be found on the bottom or side of your Xfinity router. In order to identify the gateway, the Xfinity app will ask you to scan this QR code. If you have trouble scanning the QR code, you can manually enter the CM MAC code (12 digits) printed on the router next to the QR code.
  • The app will then walk you through the rest of the setup process, giving you advice and instructions on the best router position and how to connect the cables. You will also be asked to enter a network name and password.


If none of these solutions worked for you, your only option is to contact Xfinity customer service by phone or email.

Customer support information can be found on the back of the router’s box or on their official website. Make sure to include all of the troubleshooting steps you used to try to solve your problem. This will allow Comcast to find a solution for you much more quickly.
