Non-CenturyLink modem information

Non-CenturyLink (also referred to as "third party") modems have not been tested with the CenturyLink network. CenturyLink highly recommends using one of our approved and certified modems, which have been tested and approved to work optimally with our high-speed internet technology.


CenturyLink technicians are unable to install service with non-CenturyLink equipment. So, if a professional installation is required for new service, your technician will use a new recommended CenturyLink WiFi gateway to set up and optimize the connection. After that time, if you are able to successfully connect a third-party modem, you can return the CenturyLink modem.


Please note that modems from cable internet providers do not work with CenturyLink internet service.

To order a CenturyLink-certified modem, chat with customer service.

Important to know about using third-party equipment

  • We cannot guarantee that third-party modems will work with the CenturyLink network, because they have not been tested.

  • You will receive only limited technical support from CenturyLink if you have service issues related to a third-party modem.

  • Third-party equipment is not covered under CenturyLink’s equipment replacement program.


If you understand and accept these risks and would like to use a third-party modem, you will need to get support from the modem's manufacturer. Though there are some similarities across brands, it's best to get instructions specific for your particular model's features and settings. Go to the manufacturer website (for example, Netgear, Motorola, D-Link, etc.) and search for the specific model name/number to find any user guides or help articles offered by that company, as well as customer support contact information. 

How to install a non-CenturyLink modem

If you have active CenturyLink internet service, you can follow these general setup tips:

  1. Connect your modem to a power outlet and a phone jack.

  2. Contact CenturyLink tech support to find out if your modem is "talking" to the CenturyLink network, and to get the credentials to enter to your modem.
