Usar un módem que no es de CenturyLink

When we say "bring your own modem" with CenturyLink internet service, this can describe two very different scenarios:


  1. Re-use a CenturyLink modem. Maybe you have one on hand from previous service, or maybe you got one from a friend. If it's a newer modem and the technology and speed are compatibles with your type of service (DSL vs. fiber, etc.), this is likely to work because it was built and tested for our network.

  2. Use a non-CenturyLink modem (also referred to as a "third-party modem"). Please be aware that most third-party modems don't work (or don't work well) because they aren't configured or tested on our network.  

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


We recommend using one of our certified CenturyLink modems, which are tested and approved to work with our high-speed internet technology. To order a CenturyLink certified modem, or to check compatibility of a modem, chatea con servicio al cliente.

Important information about using third-party equipment

Two points about third-party equipment

  1. Modems from cable internet providers do not work with CenturyLink internet service.

  2. In order for a non-CenturyLink modem to work with our service, it must support VLAN tagging 201.

If you want to try using a non-CenturyLink modem, please read the following FAQs closely to understand how the process works.

Our modems are maintained by our systems, including software (firmware) updates, which are important to fix bugs and keep up with security demands. We work to achieve the best experience possible with our equipment, and all CenturyLink modems are tested and certified to work with the CenturyLink network.

There are some risks that you should understand when choosing to use a third-party modem:

  • Many third-party modems will not work with the CenturyLink network, because they have not been tested or configured correctly.
  • Recibirás solamente asistencia técnica limitada de parte de CenturyLink si tienes problemas en el servicio relacionados con un módem de terceros.

  • Los equipos de terceros no tienen cobertura en virtud del programa de reemplazo de equipos de CenturyLink.

  • Our technicians are unable to install service with non-CenturyLink equipment. So, if professional installation of new service is required for any reason, your technician will use a new CenturyLink modem to set up the connection. After that time, if you are able to successfully connect your own third-party modem, you can return the CenturyLink modem.

Yes, if you understand and accept the risks involved and would still like to use a third-party modem, you may do so. You will need to get support from the modem's manufacturer. Aunque hay algunas similitudes en todas las marcas, es mejor que cuentes con las instrucciones específicas para las funciones y configuraciones de tu módem en particular. Visita el sitio web del fabricante (por ejemplo, Netgear, Motorola, D-Link, etc.) y busca el nombre/número del modelo específico para encontrar las guías para el usuario o los artículos de ayuda que ofrece esa compañía, además de la información de contacto de asistencia al cliente.

We are unable to provide a comprehensive list of non-CenturyLink modems for these reasons:

  • We can't guarantee any particular non-CenturyLink modem will work with our service.
  • Many third-party modems either do not work at all or do not provide a good experience. 
  • There are hundreds of different modem models to choose from, and those choices are constantly changing.

If you have a third-party modem that you would like to use, chatea con nosotros to check for compatibility and setup requirements. When using your own modem, the best way to connect is to let a CenturyLink agent walk you through the specifications and options.

For the more technically advanced, we can tell you that in order for a non-CenturyLink modem to work with our service, it must support VLAN tagging 201.

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

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

  2. Chatea con nosotros to find out if your modem is "talking" to the CenturyLink network, and to get the credentials you need to enter in your modem settings, including the PPoE username/password, and something called VPI / VCI.

A third-party modem must support VLAN tagging 201. For more information, see our page about installing your own modem.
