Ways To Fix the CenturyLink Modem Flashing Blue
Now that the actual reason for the ‘Blinking or Flashing Blue’ is out in the open, here is how to fix the same, depending on the problems.
1. Inspect Cables
There might be nothing wrong with your modem or CenturyLink internet. Instead, it can just be a loose connection where either the cable feeding into the device isn’t tightly fixed or the cable coming out of the wall jack isn’t in the proper condition.
A good way to fix it is by reattaching the same and ensuring that there are no loose ends in play. Quite literally.
But if that doesn’t work, inspect the splitter properly for breakage and moisture. Replace them if that’s the issue. If not, move on to the next solutions in this article.
2. Power Cycle Your Modem
The other basic strategy is to switch off the device and restart it simultaneously. This form of power cycling often gets the job done by fixing the minor issues that show up inadvertently. Note that this isn’t about resetting the modem but a normal restart where you switch the same on within a few minutes just to see it return to normal.
3. Check With CenturyLink For Outage
Believe it or not, there are many things that your ISP won’t tell you directly. And any instance of power outage might be one of them. However, in case of a power outage or any other maintenance issue, the LED light might not just blink blue but also show amber or red. If the cables are tight and the modem is new, it is better to contact CenturyLink in case of any light other than green.
4. Ensure That Modem isn’t Overheating
If the modem isn’t placed in a region where air circulation is good enough, it is common for the device to heat up uncontrollably. And you need not look here and there to validate this assumption. You can simply touch and see if the modem is hot or not.
If that is the reason, it is necessary to disconnect the less important connections to minimize load, switch it off for a while, or consider placing it in a region where the modem can dissipate all the heat generated.
5. Check for Firmware Update
If the device is slightly dated, you might have to check the firmware that comes out of the box and compare it with the latest offerings. You can flash the modem with the newest variant if the firmware needs an update.
However, the modem might act up if you upgrade it without prior motivation, i.e., even when the lights were all in the right state. You might have to downgrade to the older and more stable option to avoid blinking and other issues.
6. Reset the Modem
If you are unsure how to reset the CenturyLink modem, check for a reset button on the rear. However, resetting the device should be the last option, especially when none of the other methods work to fix the CenturyLink flashing blue light.
7. Contact Support
If the reset option doesn’t work as planned, the only option left would be to connect with CenturyLink customer support. They can do a remote test and check the quality of your internet connection or can even remote reset the modem if required.
8. Replace Modem
If none of the strategies work, you can always replace the modem, provided the warranty still holds. And while that seems like the most obvious plan, it should be your last resort as replacing might push your internet-dependent requirements back by a few days or even weeks. If your device is out of warranty, buying a new, highly compatible modem for CenturyLink is better.
