Will my modem work with CenturyLink internet?

You may have a modem that you used at a previous location or with a different provider, and wonder if you can use it for your CenturyLink internet service. This page covers which modems are recommended for the absolute best performance with CenturyLink service, which modems are CenturyLink certified and tested, and which modems may not work.

Understanding modem compatibility

It's important to know that every modem is built to work with a specific type of internet technology and in a particular speed range

CenturyLink uses different core technologies (fiber and different types of DSL) depending on your location and the speed you selected. This means that even if you have a CenturyLink modem, it will only work for your service if it is compatible with the specific technology and speed you are using.

 Recommended CenturyLink modems

CenturyLink's all-in-one modem/router, referred to as a gateway, allows you to connect your WiFi-enabled devices to the internet without additional equipment. The latest, premium WiFi gateways that we offer are the models pictured here.

When you choose to lease or purchase a modem while ordering internet service, the right gateway will automatically be selected for you based on the internet technology and speed available at your address. 

Certified modems tested for CenturyLink compatibility

"Certified" means our modems have been tested on the CenturyLink network to ensure they are compatible with our internet technology and that they perform as expected. Our technical experts determine the modem's maximum speed and check IP compatibility. All CenturyLink-certified modems include 24/7 technical support and free McAfee security protection.

The drop-down list below includes all of the certified CenturyLink modems that are currently in use. Select a brand and model to view specifications and features. If you are looking to use a different modem with your existing service, our representatives can help you determine compatibility. If you are ordering new service, you will be guided to purchase or lease the correct CenturyLink modem to get the best connection and performance. 

Modem not listed as Recommended or Certified?

If your modem is not on the CenturyLink certified or recommended modem list, it’s either a retired CenturyLink device or what’s called a third-party modem (from another provider).

CenturyLink highly recommends using one of our certified or recommended WiFi modems (gateways), which have been tested and approved to work optimally with our high-speed internet technology. Retired and third-party devices are more likely to cause performance issues and may not connect to your internet service correctly. 

If you're ready for an upgrade, contact us to purchase or lease a new modem.
