Perhaps your router, modem, or splitter is malfunctioning and signaling that it’s time to replace it. Of course, it’s always possible that some of the cables came undone. Now let’s see what we can do to resolve the “online light off” problem.


If the light on your Xfinity router isn’t steady, it means the device has lost its internet connection or is struggling to stay stable.

Before proceeding with the troubleshooting methods, consider all of the possible causes of the “online” light blinking continuously or turning off completely.

1. Xfinity Outage

An outage at your service provider’s end can cause the ‘Online’ light to continue flashing or to turn off. This could be because the service provider is performing scheduled maintenance, which you can confirm by visiting the Xfinity website. You can also contact their customer service.

2. Problems With Your Modem

Another reason you may be having trouble connecting to the internet is a faulty or damaged router. A power outage can degrade your router’s performance and cause issues when connecting to the internet.

3. An Issue with Splitter

When it comes to internet failure, one of the most common culprits is the splitter. The incoming connection is split into three separate links. One link connects directly to the television.

Another is for your cell phone, and the last is for your Xfinity router. If the splitter fails to do its job and splits the internet link, your connection will be disrupted.

4. Loose Wires

Your wires must be tightly fastened into their slots. Loose wires can cause issues, particularly with internet systems. The wires must be close together and securely plugged into their respective slots.

Now let’s see what we can do to resolve the “online light off” problem.

In this section, we’ll show you some tried-and-true methods for turning the Xfinity router’s Online light off. So let us get right to the point.

1. Reboot your Xfinity Router.

This solution is at the top of our list because it is simple, takes little time, and, in most cases, solves the problem. All you have to do is unplug the router’s power cord.

Leave the router unplugged for a few minutes (5-10 minutes), then reconnect the power cord. Wait until the router has completely booted up before checking to see if the online light is on or off. If it is incorrect, proceed to the next solution.

How to Restart Xfinity Router?

Restarting your Xfinity Gateway can resolve many common WiFi connectivity issues (our all-in-one WiFi modem and router). The process takes about 10 minutes, and your home network settings will not be lost.

If our system detects a problem that cannot be resolved through our online troubleshooting experience, we will provide the option to schedule an appointment with a technician.

Manually Restarting Your Wireless Gateway, Modem or Router:

You can restart your Gateway and most third-party networking equipment manually by following these steps:

  1. Unplug the power supply.
  2. Please wait one minute.
  3. Reconnect the power cable.

What Happens During a Restart?

You will be unable to connect to your home network while the process is being restarted. If you have Xfinity Voice, you will be unable to make or receive calls from your home phone, including emergency 911 calls, until your Gateway is restored.

You will not have access to cameras or any connected home automation devices if you have Xfinity Home. Security sensors are unaffected.

2. Check The Cables And Connectors

Loose or damaged cables and connectors – these could be the cause of the Xfinity router Online light going out.

As a result, we recommend inspecting each cable that enters and exits the router and modem. Also, make certain that each end of the cables is securely connected. When you connect an Ethernet cable, you should hear it click. Examine the cables and connectors to see if they are damaged.

If you notice something that needs to be changed, make the necessary changes. If you notice and repair the cable or connector, return to the online light to see if it is still off. Check the splitter if it is.

3. Check The Splitter

The Xfinity router Online light may be turned off due to a faulty splitter. To ensure that it is not the source of the problem, try a different splitter and see if the problem persists, or simply connect the cable directly to the router and see what happens. If the online light is illuminated, it is time to replace the splitter.

4. Check Whether You Are Affected By A Service Or Power Outage

If your ISP is experiencing network issues or performing scheduled maintenance, you will notice that the online light is turned off. This is due to the fact that there is no internet signal at all.

The simplest way to determine whether you are affected is to contact your ISP and inquire about the situation, or to use your ISP’s app or official web page. If a service outage is the primary cause of the online light going out, you will have to wait until they fix the problem. When the internet signal is restored, the online light will turn back on.

5. A Defective Router

Check that your router is operational after you have confirmed that there is no power outage and that everything is properly connected. Connecting the Ethernet cable directly to your laptop or desktop computer is the simplest way to test this.

If the Internet is now working properly, it is possible that the router is causing you problems and should be replaced.

6. Troubleshoot Hardware Issues

There have been numerous reports of wireless routers that have failed and had to be replaced. This could also be a major reason why your router’s online light is turned off. At this point, it is best to contact your ISP directly and explain the issue.

They can inspect your router and replace it with a new one if necessary. An Ethernet cable connects a wireless router to your wall outlet.

There’s a chance that this cable is damaged, and that’s why you can’t connect to the internet. You can try out a new cable to replace your old one. This will assist you in determining whether there is a problem with the line that connects your network to the router.

7. Contact Xfinity Support

If you’ve tried the solutions listed above and the online light is still on, it’s time to contact Xfinity tech support. Call them and explain the situation. If they notice a problem, they can test your line and assist you in resolving it.

They can also dispatch a technician to investigate the problem, resolve it, and eventually replace your router if it is eligible for replacement.


If you suspect a service outage is to blame for your Xfinity router Online Light being turned off, talk to your neighbors and see if they are experiencing the same problem. If you suspect that your router has a hardware problem, contact Xfinity customer service.
