Xfinity Modem Router Blinking Blue

Last updated:

To access the internet from within your house, you must first connect to Xfinity's modem. It can link your computers, tablets, and cell phones to the internet through Wi-Fi.

Xfinity internet users connect to the web using a Comcast modem. In most cases, the gadget will already be set up and ready to go upon arrival. The router's status is displayed through indicator lights.

These indicators can assist you in figuring out what's wrong with your router. Four lights on the Xfinity modem each represent a distinct function, and the blue light will flicker if there's an issue with the router.

Before calling Comcast, read on to find out why your Xfinity modem/blue router's light is flashing and what you can do about it.


What Does the White Light Flashing on a Comcast Xfinity Gateway Router Mean?

Let's briefly review what that blinking blue light on your Xfinity router means before we get into fixing it.

If your Xfinity router or modem has a blue light that flashes, it is probably in WPS pairing mode. Wi-Fi Protected Setup, or WPS for short, is a function provided by Xfinity that allows you to connect devices with Wi-Fi capabilities to the network without needing the password.

There may be a different issue if the Xfinity modem/router isn't in WPS status when the blue light blinks. Whatever the reason, we will look at several methods of getting the blue light on your Xfinity router to stop blinking so you can reconnect to your network again.

How To Stop Your Xfinity Router's White Light from Flashing

Fixing an Xfinity modem or router's blinking blue light can be done in a few different ways. Try each of these options until you identify one that works.

Activate Wi-Fi Protected Setup (WPS) on Your Xfinity Modem/Router

Try pushing the WPS button on the Comcast modem to see if it stops the blinking blue light. If your Xfinity device's blue light was flashing because it was in WPS mode, it should disable WPS mode and fix the problem.

The location of the WPS button and restart instructions vary slightly depending on which gateway model you have.

xFi Advanced Gateway (XB7 and higher)

The WPS button is located on the back of the device, above the coax and Ethernet plugs. WPS connection mode is indicated by the blue LED light slowly blinking on the xFi Advanced Gateway (XB7 and above). After the connection is made, the light will change to pure white in operational mode.

xFi Advanced Gateway (XB6)

To find the WPS button, look to the top and left of the gateway box. After the button is pressed, the blue light slowly blinks as it pairs with your home network. The light changes from blue to pure white when the pairing has been completed.

Wireless Gateway

The button is located on the top, toward the front of the Xfinity router. The Wireless Gateway's WPS button will initiate a connection, and the WPS LED will blink until the connection is complete. In the event of a failed connection, it will flash for five minutes. It would be best to wait for the LED to stop blinking before attempting again or attaching another WPS device.

Once your Wi-Fi has successfully connected to your local network, the system will show a confirmation message on the screen. If the Xfinity blue light persists, you can attempt these other solutions.

Restart The Device

If hitting the WPS button does not stop the blinking blue light, you can try rebooting your Xfinity modem or router. To accomplish this, disconnect your Xfinity device from its power source, wait 15 seconds, and reconnect it.

Wait for the device to fully boot up before reconnecting any devices.

Double-Check Connections

If the Xfinity blue light continues flashing after attempting the previously mentioned troubleshooting steps, it may be caused by a problem with a cable or connection. Here's how to resolve the issue:

  1. First, unplug the power from your gateway. Not every model has coaxial or ethernet cables connected in the back. If your model does have these connections, test them by removing them from the back of your Xfinity modem or router.
  2. Wait a few seconds, and then plug them back in.
  3. Check to see if the light is still flashing blue or if it has turned to white. If it's still flashing blue, move to the next step.

Reset to Default Settings

Finally, if you've exhausted all other troubleshooting steps and your Xfinity device's blue light is still flashing, you may try resetting it to factory settings.

Any changes you've made to your Xfinity device's settings will be lost if you do this, so be sure to make a backup. When you hit and hold the reset button for around 10 seconds, it will reset your Xfinity device to its original settings.

Wait a few minutes after returning your Xfinity equipment to factory settings to see if the blinking blue light stops.

When everything else fails, and your Xfinity modem or router's blue light continues to flicker, it's time to call Xfinity's customer service.

Get in Touch with Xfinity's Support Team

If you've tried all these options and still have trouble with your Xfinity router, you should call Comcast for help. A technician may need to visit your home to investigate the issue.

You may contact Comcast's support team via their website or by dialing 1-800-XFINITY.
