Few things are more annoying than a buggy internet connection, especially when you want to stream a favorite show or when you actually have a chance to win a Fortnite match. Thankfully, fixing your CenturyLink internet can be easier than you think. Let’s get you back to streaming Netflix ASAP!

If you’re ever in over your head fixing your CenturyLink internet, you can always chat with technical support online, or call them directly at +1-866-642-0444.

Is it time for a new internet provider? Look for internet service available near you.

Why do I have no internet connection?

If your internet connection is completely shut down, it’s most likely one of these two scenarios:

  1. CenturyLink internet is down in your area. You can check here if CenturyLink internet is down in your area. If it is down, there’s not much you can do except wait until CenturyLink gets everything back up and running.
  2. Something is wrong with your modem. Let’s dig into how you can fix your CenturyLink modem. Thankfully, many of these fixes can be pretty simple.

How to fix your CenturyLink modem

First of all, go and grab your modem. It should look like one of the two modems shown below:

There are a bunch of flashing lights that probably seem intimidating at first glance. The first thing we want to check is whether or not your modem is getting any power. On the far left side of the box, you’ll see the power light. It will look something like this:

We want to see a green power light, but your power light could be red, amber, or off altogether.

Red or amber light

You’ll see a red or amber power light when the modem tests its own hardware. Hopefully the light will stay red for about 30 seconds and then transition to green. If it stays red, then here are some possible reasons:

  • You're using the wrong cord for power supply. Make sure you use the one they gave you.
  • Your modem has overheated. Move your modem to a spot where it gets better air circulation.
  • You’re not getting enough power from your power strip or surge protector. Try plugging your modem directly into an outlet.

If nothing else works, you can reset your Wi-Fi router. You can do this by using a paperclip to press the reset button until the lights go out. This will reset your modem to factory defaults.

No light at all

If the power light isn’t turned on, then you’ll want to check the power cord and make sure it’s plugged in. If it’s plugged in and you’re still not getting power, then it’s possible that no power is coming through the outlet. If there’s no power in the outlet, then you’ve got a bigger problem than an internet outage, friend. I’d call an electrician.

If your power light goes to green, the rest of the lights on your modem box should start to light up green as well. Here is a quick checklist of everything you need to make sure every other light goes green as well:

  • For the DSL light, you want to make sure you have an Ethernet cord plugged in to your box. If an Ethernet cord is plugged in and the port still isn’t turning green, you should try a new Ethernet cord.
  • The internet icon will turn solid green once your modem connects to the internet. If that icon flashes red or amber, it’s either because your login information is incorrect, or the internet is down in your area. This would be a good time to get in touch with technical support.
  • Your Wi-Fi light will be turned off if you don’t have it enabled. Here’s how you can set up your CenturyLink Wi-FI:
    • Open a web browser and go to
    • Select Wireless Setup.
    • Select Basic Settings.
    • Select Enable next to Wireless Radio.
    • Select Apply to save changes.

Long story short, if you have double-checked that everything is plugged into your modem correctly, and the internet isn’t down in your area, your internet should work reliably.

Want to speed up your internet connection?

It’s possible that your internet speeds are so slow that it feels like your internet just shut down altogether. You can always check your internet speed and see what you’re working with. There are a few other things you can do to speed up your connection to speed up your connection right now, like moving your router to a place with less interference. But if you’re experiencing constantly slow internet speeds, or internet connection at all, it might be time to consider moving to a better internet service provider.
