They Might Be Down or Under Maintenance  

Are they down or are they undergoing maintenance? Check with the customer service of your ISP immediately! You can contact them via their hotline for the fastest response.

  1. Contact them and inquire if there are any outages or any maintenance going on
  2. You can also search the web for any similar experiences happening as of the moment
  3. Moreover, you can also check if they’re down through the Down Detector Browser Program

Check Your LAN Cables

The next thing you have to look at and check would be your LAN cables. They are the cables that connect your PC or your laptop to your modem.

  1. Detach the LAN cable from your PC to your router in both ends
  2. Try switching the two ends
  3. In order to guarantee that they are attached, you need to hear a “click” sound

There are some instances where the connectors are not detected by the input. All you have to do is to detach and reattach them.

Check Your Router or Your Modem

Your medium might be the problem. Regularly, their usual modem should have the green power light on; that means everything is working fine and properly.

But what if it’s not?

  1. Try restarting the modem by unplugging the power cable.

2. Plug it back on again. For 30 seconds, the light will become red. It’s a signal that the modem is testing itself. If not, then it could be because of the following reasons:

  • You might be using the wrong cable.
  • Overheat
  • Insufficient power (plug the modem to a socket or an outlet directly)

3. Red lights on the internet icon means that the credentials you have put are incorrect. Or, it’s a reason that your service is currently under maintenance from where you are.

Check Wi-Fi Status

If you are experiencing problems with your Wi-Fi, then you need to make sure that the Wi-Fi icon on your modem is enabled.

Update Your Wi-Fi Drivers

In case you are not aware, your Wi-Fi is working because of drivers and firmware that your ISP gives you.

If you are experiencing a sluggish connection; or if it’s constantly dropping, you might want to give updating your drivers a try.

To update your drivers or your firmware:

Step 1. Connect your PC, laptop, or your smartphone to the web. If you do not have a connection, you’ll need to use an Ethernet cable to connect your PC or your laptop directly to your modem.

Step 2. Open a browser and in the address bar, type in

Step 7. Click on Download

Step 8. Afterwards, hit on the Save As button

Step 9. For you to be able to find it easily, save it on your Desktop or where you know you’ll locate it

Step 10. After its successful installation, choose Browse from the list of options in the Upgrade Firmware screen

Step 11. Find where you saved it and select Open

Step 12. Proceed by clicking Upgrade Firmware

It might take a couple of minutes to be completed. Once done, it will automatically reboot the router. Once done, both the DSL and the internet lights will turn red – you just have to wait for 2 to 3 minutes and it’ll be restored.

This method is also effective and applicable if you are being annoyed because the CenturyLink DSL keeps disconnecting.

Contact Their Tech Support

After doing all the steps and you are still not satisfied with how your connection is, the next best step is to contact the technical support of your ISP.

There might be problems with their router itself, and they might need to replace it.


Nevertheless, here are the steps you can take if you want to be free from the error that CenturyLink internet keeps disconnecting. They are easy and they are proven and tested, given that your router is not damaged or broken.
