If you’re using an Xfinity Internet router, then you might face an issue where it blinks ‘red light’. Xfinity router red light issues are common and can occur sometimes due to several reasons. Fortunately, we’re presenting you with fixes for when your Xfinity router/modem is blinking red light. Using these fixes, you’ll be able to resolve the issue easily. So, let’s get started:

What Does Red Light Mean on Xfinity Modem?

Before we dive into the fixes, it’s important to know what the red light means on your Xfinity modem. If you look at your Xfinity router blinking red light, then it means that you have an interrupted internet connection. There can be several reasons for this:

  • There’s a disruption at the provider’s end.
  • Your connection isn’t established (the Ethernet cable can be unplugged).
  • The router isn’t connected to the primary internet connection.
  • The custom setting on the router isn’t allowing connectivity.

These can be some reasons why your Xfinity router is blinking red light. You can also check out our blog on Xfinity Internet modem, which will guide you better in terms of understanding your modem.

How to Fix Red Light on Your Xfinity Router?

We just discussed the potential issues that cause your Xfinity router to blink red light. Now it’s time to check out some of the fixes that you can apply to get rid of the problem:

1. Check for a Cable Disconnection

Another easy fix is to see if the Ethernet connection to your Xfinity router is connected properly. Sometimes, the connector head becomes loose or broken, which is why it disconnects, resulting in the router blinking red light. Make sure all Ethernet cables are securely plugged in.

In addition, if you have a separate modem and router, then ensure that the Ethernet cables connecting them are secure. Replace any cable that is loose or damaged since it can cause disruption too.

2. Restart Your Modem/ Router

In many cases, a simple reboot is enough to resolve the pertaining issue. If your Xfinity router is blinking red light and you’ve tried the above fixes, then try rebooting the device. A simple reboot will reconnect the device with the primary internet connection and will resend/ receive data packets.

Furthermore, you’ll need to do this for your modem and router separately if you don’t have a modem-router combo. Turn off both devices for at least 30 seconds and then power them on. It should resolve the issue.

3. Try Resetting Your Router

In case you’ve tried rebooting your internet router and the red-light issue persists, it’s time to reset your device. For this, you can locate the reset button on the rear of your Xfinity router. Using a thin object, press and hold the button for about 10 seconds.

This should reset the router (the LEDs will turn off and reset the device to the factory default settings, and turn back on). However, any custom settings (QoS settings) applied will be removed, which is why you have to make sure to save them for later.

4. Checking for an Outage

Earlier we highlighted that there might be an outage at your provider’s end. In such a case, you’ll have to contact Xfinity customer support to know if there is one and get a timeline for the fix. If your Xfinity router is still blinking red light, then the outage hasn’t been fixed yet.

The above fixes can be used to deal with Comcast Xfinity modem/ router blinking red light problem. If the issue persists, make sure to contact Xfinity support right away and get professional assistance.
