Installing your own modem

Thank you for choosing CenturyLink for your internet service. If you are providing your own modem for your service, there are a few things you'll need to know about installation and activation.

Is it compatible?

If you have not already done so, please verify that your modem is compatible with your new service. If you are re-using a newer CenturyLink modem, it will most likely work. To be sure, check our compatibility page and contact us with any questions.

Setting up service when re-using a CenturyLink modem

If you are installing a CenturyLink modem that you already have from previous service, do the following:
 

  1. Plug in the modem's power cord and perform a factory reset. This is necessary to clear the previous credentials and allow the equipment to connect to your new service.

  2. Connect your modem with an Ethernet cord. Once the modem is reset, as long as your CenturyLink service is active, the modem should connect automatically. For more guidance, see our modem setup instructions.

Note about line activation: Your line should be activated no later than 7 p.m. on your service start date, at which point you can connect your modem.

Setting up service with a non-CenturyLink modem

If you are using a non-CenturyLink modem, first you'll need to verify that it meets the technical requirements to work with our service, including supporting VLAN tagging 201. Keep in mind that many third-party modems do not work with CenturyLink service.
 

Modems from cable-internet providers will not work with CenturyLink service.

Contact us to get modem settings

If you have a modem that you think will work, chat with us to get the credentials you need to manually enter into your modem settings:

  • PPoE username and password
  • VPI / VCI


You will not be able to connect your modem to our network without these credentials.
