On most Wi-Fi router/modem devices, a blinking light means either of two things: one, an activity is going on. Or, two, something is wrong. The case of CenturyLink modem routers is not different, either. So, when you come across a CenturyLink modem router blinking blue, you may feel a little anxious, especially if there is no internet access. But I will tell you what the blinking blue light means and how to fix it.
What Do Status Lights Mean on CenturyLink Modem Router?
Like many other modem router devices and wireless gateways, the CenturyLink modem router also uses a multi-color LED panel to show the router’s status. Different colors refer to various aspects, though. A light may indicate the internet status, whereas another may be used for a WPS connection.
The blue light on the CenturyLink modem router indicates the connection status. So, when you turn on the router, you will see a blue light as the device attempts a connection. However, this process should not take more than a few minutes. If the light keeps blinking blue even after five minutes, there are some issues.
This essentially means that the CenturyLink modem router cannot connect to the CenturyLink network and, thus, the Internet. You have to keep this point in mind while going through the potential reasons for the blue light and its solutions.
Why Is My CenturyLink Modem Router Blinking Blue Light?
Now, I’ve already told you that a blinking blue light means the modem is attempting a connection. However, multiple factors may cause this delay in establishing the connection. Some of these are hardware-based, but others happen due to software issues, too.
Here is a quick list of the common reasons why a blinking blue light does not go away on CenturyLink routers.
- A faulty or incorrectly connected cable—power and network—can cause the blinking blue light.
- CenturyLink network infrastructure in your region may be facing an outage or under maintenance.
- A faulty router firmware may prevent the CenturyLink modem router from connecting.
- Overloading and overheating of the modem router are also common reasons for this issue.
- You might also have a faulty CenturyLink modem/router or might have an improper configuration.
So, when you look for solutions, you need to consider all these factors. Of course, you can get in touch with CenturyLink anytime and request a professional appointment. However, this process may take time and cost a bit of money.
How to Fix CenturyLink Modem Router Blinking Blue
Here are some potential solutions you can try to fix the CenturyLink modem router blinking blue. As always, I have kept them in the order of easiness. So, you can try the easy solutions before attempting a reset or a replacement.
#1 Restart the Router
First, you need to restart the CenturyLink modem router to see if the blinking blue light goes away. It should probably go away if we are dealing with a temporary issue. Make sure you wait for 5 minutes for the router to connect to the Internet.
#2 Check Cables and Ports
Cables and ports on the CenturyLink modem router must be connected properly. In particular, check both the coaxial cable and the Ethernet cables. It also makes sense to confirm whether you are using a first-party power adaptor to avoid voltage-related issues.
#3 Look Out for Outages
Network outages can also cause a blinking blue light, as they can stop the CenturyLink router modem from connecting to the Internet. I recommend checking CenturyLink’s official website or contacting the local service provider. You can also check Twitter and sites like Downdetector.
#4 Update Firmware
If the problem is not solved after a few hours, you should suspect a faulty firmware. The solution here is to install a newer firmware update from CenturyLink. You may need to install a separate update if you use your modem with CenturyLink.
#5 Avoid Overloading
If you have connected too many devices to the Wi-Fi network, the CenturyLink modem router may face some overloading issues. It is a common issue because a single device has to act as a modem and router. You can avoid this situation by limiting the number of connected devices. Also, keep the device in a ventilated space.
#6 Reset the Router
At this point, you have a better chance of solving the blinking green light by resetting the CenturyLink modem router device. You may have access to the router control panel, but I recommend using the Reset button on the rear panel of the device.
Press and hold this button for at least 15 seconds, and the reset process should start.
#7 Contact CenturyLink
If a system reset does not solve the blue-blinking light problem, you are probably stuck with a faulty device. It is then better to contact CenturyLink, which will either replace the router or check for surrounding issues. It might also be an issue with a nearby network splitter.
Conclusion
As you probably understood, solving the blinking blue light on the CenturyLink modem router is not rocket science. It should not be, either.
But I advise everyone to be patient. Sometimes, the router might take more than 5 minutes to connect to the network.
So, try these solutions only if you have been facing the issue for an extended period.
