Install CenturyLink internet

The CenturyLink installation process is pretty simple, so anyone with some basic tech knowledge should breeze through it. CenturyLink’s clear instructions make it even easier. Let’s take a closer look at the step-by-step process.

What’s in your CenturyLink installation kit?

Your kit includes everything you need to get started:

  • CenturyLink modem
  • Black power cord
  • Green cord
  • Yellow Ethernet cable

It’s a good idea to check the kit as soon as it arrives before you start the installation. That way if something is missing, you can get it before you’re in the middle of things.

If you’ve got your kit and everything is present and accounted for, you’re ready to start the installation process.

How do I install my CenturyLink modem?

Getting your CenturyLink internet installed is easy. There are just a few steps, and CenturyLink provides detailed and easy-to-follow instructions with your kit. Here’s a rundown of the process:

1. Connect the power cord

Connect the black power cord into your CenturyLink modem, and plug it into an outlet near your computer.

2. Watch for the blinking power light

The power light will start blinking and eventually stay lit. This should only take a minute. Once it’s lit, you’re ready for the next step.

3. Connect the DSL cable

Connect the green cable to the port labeled “DSL” on your modem. Plug the other end into a phone jack near your computer.

4. Watch for the blinking DSL light

The DSL light on the modem should start blinking. When it stops, you’re ready to move to the next step.

If the light doesn’t turn solid green after one minute, verify that your service is activated. You should have received a letter with the installation kit letting you know your activation date. If nothing is wrong with that, try a different phone jack.

5. Connect the Ethernet cable

Connect the yellow Ethernet cable to the modem. Plug the other end to the Ethernet port on your computer. The Ethernet indicator on the modem should light up.

6. Open your web browser

Open a web browser on your computer. You should be automatically taken to the CenturyLink internet setup page to complete the online installation.

If your browser doesn’t automatically redirect to the page, check that you completed the other steps properly and make sure all cables are firmly attached. Next, visit

7. Set up your Wi-Fi connection

To set up your CenturyLink Wi-Fi connection, locate the network name and password on the back of your modem.

  1. Use this info to connect to the wireless network.
  2. Once connected, open your web browser and visit to complete the setup.
  3. Repeat for each computer that will use a Wi-Fi connection.

That’s it! You should now be online and ready to use your CenturyLink High-Speed Internet. If you need additional help or run into any issues, call CenturyLink customer service at 1-855-331-1346.

Heads up!

If you have a landline phone, you’ll need to order phone filters from CenturyLink for them to function properly after installation. Call CenturyLink at 1-855-331-1346 to get yours.

Activating your CenturyLink internet service

When you order your CenturyLink High-Speed Internet, you’ll be given a service activation date. After this date, your service will be activated automatically, so you shouldn’t need to do anything special to get online once you’ve installed your equipment and set up your computers.

If you run into problems or your service doesn’t seem to be activated, call CenturyLink support at 1-855-331-1346 for additional help.

Pro installation vs. standard installation

Pro install


  • No technical experience necessary
  • Service tech that can handle any issues that arise on the spot


  • $99 fee
  • Required appointment window

Standard install


    • $15 fee (waived if you have fiber gigabit)
    • No need to wait for an appointment—install whenever you like


  • No tech to make sure things work—you’ll need to troubleshoot problems yourself
  • Some (not much) technical knowledge required

Standard installation is an enticing option, but it’s not for everybody. To decide if it’s right for you, ask yourself whether the convenience and lack of fees outweighs the idea of troubleshooting problems on your own. If that’s no problem for you, the DIY route is an affordable way to go.

Why it’s good

Choosing the professional installation option takes all the pressure off you. All you have to do is be there for the appointment, and the tech will handle the rest.

This is ideal for folks that lack the technical know-how to do a self-installation and would rather let the pros handle it if something goes wrong.

What to expect

When you order your service and choose pro installation, you’ll be given an appointment date and time. Make sure someone over 18 is present for the appointment.

Installation can take up to six hours, depending on the amount of work needed, so you might need to take off work. If you need new outlets or wiring installed, for example, it will definitely take longer than usual.

How to prepare

You can track your installation tech’s ETA using a handy tool provided by CenturyLink. This will give you a rough idea of when to expect your tech to arrive. Oh, and by the way, any rescheduling needs to be done 24 hours in advance.

Other than that, just make sure the tech has easy access to computers and wall outlets by moving furniture and other decor. It’s also a good idea to make sure your pets are out of the way. The tech should take care of the rest.

Heads up:

CenturyLink often runs promotions that offer discounts on installation and equipment. See our best internet deals page to find something sweet.

Equipment: renting vs. buying



  • Guaranteed to work
  • Comes with easy technical support


  • May charge monthly fees
  • Often lacks advanced features, such as long-range wireless



  • Flexibility to choose equipment that’ll suit your unique needs
  • No monthly fees


  • Can cost quite a bit upfront
  • Doesn’t come with support for third-party modems and routers


CenturyLink provides a modem and router to each new customer to help you get online easily. For most people, this equipment will be plenty powerful. The CenturyLink rental fee is $10 per month, or you can opt to purchase it outright for $150.

Although the equipment is relatively basic, it’s guaranteed to work with your service, so that makes it an attractive option. You can just hook up your equipment and be done thinking about it.


You can also choose to use your own equipment, whether you already have a modem lying around or want to purchase something new. CenturyLink provides a list of compatible modems.

In some cases, buying your own equipment can be cheaper than leasing from your provider, but generally the cost savings are minimal. There’s also a chance you’ll have to buy different equipment if you move to a new provider in the future, so keep that in mind.

Our verdict

For most people, we recommend sticking with the equipment provided by your ISP. Unless you need a really souped up router, going with what’s provided just tends to be easier.

Enjoy your CenturyLink service

Whether you choose to self-install or let the pros handle it, the setup process for CenturyLink internet is about as simple as it gets. So relax, grab your favorite person, and fire up Netflix—those shows aren’t going to watch themselves!
