How to reset your CenturyLink modem to default settings

A reset restores your modem to its factory default settings. It will also erase any customized settings you may have changed, including static IP address setup, DNS, personalized password, WiFi settings, routing and DHCP settings. If you have custom settings, you can back up your settings before doing the modem reset and then restore them again once the reset is complete.

When to do a modem reset

Before we explore how to reset your modem, it’s important to discuss when it is appropriate to do a factory reset. If your modem isn't working right, or if you changed some settings you can't undo, you may decide it's time to reset your modem to its default settings.

Before you do, however, it's always worth doing a simple reboot first. If you haven't already tried rebooting (restarting) your modem, click the link below to see instructions for three different ways you can reboot.

A full factory reset returns your modem to its out-of-the-box settings and may fix the following issues:

  • Gaming problems
  • Routing errors
  • Can't connect to the internet errors
  • Slow connection speeds
  • Choppy VOIP 
  • Port connection issues 
  • Wireless network issues
  • Device conflicts

How to reset your modem

The preferred method to reset your modem is by logging into the user settings interface. If this isn't an option, you can do it manually using the reset button on the back of the modem.

Important note:  If you customized your modem login information at any point, performing a factory reset will cause the network name (SSID) and password to revert back to what they were when you received the modem. These are shown on the modem sticker, and you will need to use these original login credentials the first time you log into the network again.
