Modem troubleshooting tips

Quick setup

Manual network (WAN) setup

If instructed to do so by a technician, you may need to change the WAN settings on your modem manually. Visit the WAN setup page for step-by-step instructions on different WAN configurations, including PPPoE, IPoE and transparent bridging.

Your modem's wireless settings control the WiFi network in your home. This model of router has 2.4 GHz and 5 GHz options for most wireless settings, with exceptions noted below. Click on the options below for details and step-by-step instructions.

Helpful WiFi topics

The modem status area of the user interface allows you to view several options and check how your modem is running. 

  • Firewall status
  • Device table
  • NAT table
  • Routing table
  • QoS table
  • Resource table

The utilities menu gives you access to several additional tools to manage and test your modem. 

Advanced settings give you even more control over your modem's configuration. Most of these are best for tech-savvy folks who are familiar with modems and networking. 

On modems that have Secure WiFi, some advanced features in the modem settings will be disabled, including:

  • Access scheduler
  • Service blocking
  • Website blocking

Instead, you can easily access these same network controls through My CenturyLink or the app. Secure WiFi is available on leased modems with model numbers 1100, 3000 and 4000. Review our FAQs to learn more.

Setting up new service? Please note that a phone jack is required to set up CenturyLink internet service in your home. If you don't have a jack, chat with us to have one installed.
