Why Is My WiFi Router Blinking? [7 Reasons]

If you’re experiencing a blinking router light, it might be time to replace your device. Why Is My WiFi Router Blinking?, Routers use a range of different technologies, and as these technologies evolve, so do the blinking lights that indicate their status.

Routers that use Wi-Fi signal technologies, for example, might blink faster than those that use cellular signals. And routers that are more than a few years old might not support the latest networking standards.

If you’re noticing your WiFi router blinking like crazy, it might be time to replace it. The blinking light is a common sign that your router is in need of repair or replacement.

What Is WiFi Router?

A WiFi router is a device that allows devices within a certain range to connect to the internet using WiFi. A person can use a WiFi router to create a home network, which allows multiple devices to connect to the internet at the same time. A WiFi router can also be used to extend the range of a home network.

How Does the WiFi Router Work?

The wifi router is a device that allows devices within a certain range to connect to the internet. The router creates a local area network, or LAN, and uses special radio signals to do so. These signals are then picked up by devices like laptops, smartphones, and tablets and allow them to connect to the internet.

The wifi router is usually placed in a central location in the home so that all of the devices within range can connect easily. The range of the wifi router can vary depending on the make and model, but it typically extends throughout most of the home.

The wifi router works by connecting to an internet service provider, or ISP. The ISP provides a broadband connection that the router uses to create the local area network. Once the network is created, devices can then connect to it and access the internet.

Why Is My WiFi Router Blinking?

The blinking of a router is not normal and, in some cases, it can be an indication of a problem with the device. There are a few things that could cause the router to blink, but most of them are easy to fix.

1. A Possible Power Issue

If you are experiencing problems with your home router, such as the device continually blinking or not working properly, it could be a sign that you have a power issue. One way to test this is to plug the router into another outlet in your home.

If it still doesn’t work, the problem could be with the router itself and you may need to replace it. If it does work when plugged into a different outlet, then the issue is likely with your original outlet. In either case, it’s best to consult with a professional to determine what is causing the problem and how to fix it.

2. The Router Might be Overheating

If your router starts blinking, it might be overheating. This can be caused by a number of factors, such as the age of your router, how many devices are connected to it, or the amount of traffic on your network. You can try some basic troubleshooting steps to help cool it down and stop the blinking.

First, make sure your router is in a well-ventilated area. If it’s in a cabinet or closet, move it to a location with more airflow. You can also try using a fan to blow air on the router.

If that doesn’t work, you might need to take more drastic measures. Unplug your router and let it cool down for 30 minutes. Once it’s cooled off, plug it back in and see if the blinking has stopped. If not, you might need to replace your router entirely.

3. There Could be a Connection Issue

If your router is blinking, it could be an indication of a connection issue. If your router is not working correctly, you do not be able to connect to the Internet Connection. You can try some troubleshooting steps to see if you can fix the problem.

Make sure your cables are plugged incorrectly. Next, reset your router by unplugging it and plugging it back in. If you’re still having problems, you may need to call your internet service provider.

4. The Firmware Might Need an Update

When a router starts blinking, it can be a sign that the firmware needs an update. If the firmware is outdated or corrupted, it might not be able to properly function, which could result in blinking lights. One way to try and fix this is by updating the firmware.

Some routers might have an automatic update feature, while others might require manual intervention. If there is no automatic update feature, or if the update doesn’t work, then the user might need to contact the router’s manufacturer for more help.

5. The Router Might be Infected with Malware

When you see your router flashing and it’s not supposed to, it can be a little disconcerting. It’s important to know what the problem might be and how to fix it.

The possibility is that the router is infected with malware. If this is the case, you’ll need to take some steps to remove the infection and protect your device from future attacks.

6. The Router’s Settings Might Have Been Changed

If your router is blinking, it could be that the settings have been changed. This might have been done intentionally or by accident. If you recently changed the password or username, this might be the cause of the problem.

Another possibility is that your router has been infected with a virus. In this case, you will need to scan your computer for viruses and remove them. If none of these solutions work, you might need to reset your router to its factory settings.

7. You Might Need a New Router

There are a few reasons your router might be blinking. One possibility is that the firmware on your router is outdated and needs to be updated. Another possibility is that there is too much traffic on your network and you need to upgrade your router’s bandwidth. If neither of these solutions works, then you might need to buy a new router.


In conclusion, your WiFi router may be blinking because of a variety of reasons. By troubleshooting the issue, you can determine the cause and fix it. If you are still having trouble, consult with your internet service provider or router manufacturer for assistance.
