How To Fix Internet Light Blinking On Router? [5 Easy Fixes]

The internet has become an absolute necessity for so many of us. We no longer rely on it solely for email; it now powers our smart homes, allows us to order food, and allows us to work from home if necessary. It is now almost considered a human right in some parts of the world.

However, a variety of issues can arise due to the complexity of the devices we need to power our connections. The more complex the device, the more likely it is to fail. At least, that’s how it appears to work for us! Routers are no exception.

The internet light blinking on router is one of the most common router issues. Because blinking lights are rarely a good sign, we’ll explain why this is happening and how you can fix it.

Troubleshooting: Issues on Fixing Internet Light Blinking On Router

Issue	Solution
Loose or damaged Ethernet cable	Make sure the Ethernet cable is properly plugged into both the router and the modem. If the cable is damaged, replace it.
Outdated firmware	Update the router’s firmware to the latest version. You can usually download the latest firmware from the router manufacturer’s website.
Faulty router	If you’ve tried all of the above and the internet light is still blinking, the router may be faulty. In this case, you’ll need to contact your router manufacturer for a replacement.
Service outage	If your internet service provider is experiencing a service outage, the internet light on your router may be blinking. You can check the status of your ISP’s service by visiting their website or calling their customer service line.
Firewall blocking the internet connection	If your firewall is blocking the internet connection, you’ll need to disable it temporarily to troubleshoot the issue. Once you’ve identified the problem, you can re-enable the firewall.

WHY IS BLINKING INTERNET LIGHT ON ROUTER HAPPEN?

When the light on a wireless router continues to blink and you can connect to the Internet, it means the device is operational. However, if the device’s only function is to blink, there could be a problem.

Most router problems can be resolved with a few simple troubleshooting tips, but you may need to seek the assistance of an electronics repair professional in the end.

TRANSMISSIONS

When transmitting data to a Wi-Fi device, such as a computer or mobile phone, the lights on a wireless router, like the lights on a modem, blink. The blinking light can be ignored as long as the Wi-Fi device can receive and send data over its wireless connection to the router.

When the router sends and receives data transmissions, the lights on the device blink, indicating that the data has been properly processed and sent to either the Wi-Fi device or the modem.

CONSTANT BLINKING

Even when no Wi-Fi devices are connected, the lights on a wireless router will blink. This is due to the modem, to which the router is linked, constantly processing data transmissions from the Internet.

The Address Resolution Protocol (ARP) process involves the modem converting 32-bit Internet provider Web addresses into 48-bit Ethernet addresses. Ethernet refers to all devices that are wired or cabled to a modem, including a wireless router. When the router sends or receives data, its lights, including those produced by the ARP, blink.

CONSIDERATIONS

Most wireless routers can support wireless connections for up to five Wi-Fi devices simultaneously. The rate at which the router’s lights blink increases with each connected device.

When the router’s support limit is reached, the blinking lights may remain illuminated indefinitely because the router is sending and receiving transmissions at a much faster rate than when fewer devices are connected.

When there are no blinking lights on the router, it is a dead giveaway that something is wrong. If this occurs, ensure that the router’s wires are properly connected to the modem and a power outlet. Contact an electronics repair professional if all troubleshooting attempts fail to get the router to work.

WHY IS THE INTERNET LIGHT BLINKING ON ROUTER?

When creating these guides, we always try to explain the problem before we fix it. Our goal is to help you understand why these things are happening so that you can fix them much more easily if they happen again. The blinking light isn’t a major issue. It does not imply a catastrophic failure.

Instead, it simply indicates that the internet signals are weak. The router is telling you that it is having trouble connecting to the internet. This makes it pretty clear what we need to do. We must now repair your internet connection. Let’s get started right away!

1. A FAULTY CONNECTION BETWEEN THE ROUTER AND THE MODEM

The most likely cause of the flashing light problem is a faulty connection between your router and modem. These kinds of things tend to occur naturally over time. To determine whether this is the case, inspect the USB cable that connects the two devices.

What you should look for is that both ends are as tightly plugged in as possible. Then we’ll look for physical signs of damage. If you notice any fraying of the exposed innards, it’s time to replace the cable completely.

While you’re here, make a point of straightening out any sharp bends in the wire. As a result, your cable will deteriorate much faster than usual.

2. THE ROUTER MAY JUST NEED TO BE RESTARTED

If the cable appears to be in perfect working order, we will need to move on to more technical issues. When things like this happen, it could result from a minor bug or glitch that is interfering with your network’s performance.

Fortunately, most of the time this can be resolved by simply restarting the router. Here’s how we think you should go about it.

Rather than simply turning off the device, we recommend unplugging it completely. In addition, make sure you unplug any cables that may be connected to it. Essentially, this ensures that no power enters the router.

After finishing all that, just let it sit idle for at least a minute. Then, using the ethernet connection, connect the device to the modem to ensure that it can establish a connection.

All that remains is reconnecting the power and seeing if it establishes a proper connection. That’s fantastic. If not, we’ll have to move on to troubleshooting the modem.

3. CHECK THE MODEM

We recommend that you use the ethernet cable to connect your computer to your router directly for the next step. This way, you won’t have to rely on the device’s wireless component. In general, this will increase your internet speed and solve the problem.

You should also ensure that the modem is operational. If it is, we recommend that you contact your internet service provider to ensure that the problem is not on their end. It is frequently the case.

4. MAKE SURE THAT YOUR FIRMWARE IS UP TO DATE

If the light on your router continues to blink and you are unable to connect to the internet, this indicates that the router’s firmware is out of date. When these items are out of date, they do not function as well as they could. In the worst-case scenario, this means that it will not work at all. Fortunately, this is a simple problem to solve.

All you have to do is go to your router’s official website. Though these layouts will differ greatly from one brand to the next, there will always be a button to check for firmware updates.

If there are any you may have overlooked, we recommend downloading them as soon as possible. Once you’ve downloaded it, connect the router to the device you’re attempting to connect to the internet on, and you should notice that the problem has been resolved.

5. PERFORM A RESET ON THE ROUTER

As a last resort, you can completely reset the router. For most routers, you must locate the reset button and press it for at least ten seconds. In many cases, the button will be built into the device.

This means you’ll need some tool to poke at it. A pencil or a needle will suffice. After the reset, the device will reboot and hopefully resume normal operation within a minute or two.

CONCLUSION

Unfortunately, these are the only fixes that we can recommend from the comfort of your own home. If none of these have worked, the only logical next step is to enlist the help of professionals.

We would recommend contacting customer support because the problem is most likely quite complex. While talking to them, tell them about all of the steps you’ve taken so far to resolve the issue. They will be able to get to the bottom of the problem much faster this way.
