How to reboot your modem

Rebooting your modem is the first thing to do when your internet connection is slow or spotty. A quick reboot does the following:
 

  • Clears the modem's memory
  • Refreshes the network connection
  • Locates the best WiFi channel to reduce interference 
     

You can reboot manually, and many customers can also do it through our app or on the My CenturyLink website.

Important: Always reboot your modem after an outage.

Note: All devices on your network will lose their connection to the internet while the modem restarts. Devices set to remember your network will reconnect automatically once it boots back up. Otherwise, you'll need to use device settings to reconnect

How to reboot manually

To reboot your modem manually, follow these steps:

 

  1. Unplug the power cord from the back of the modem or from the wall outlet, whichever is easier. Check that all the lights on the modem go off to make sure you unplugged the right cord.

  2. Wait 30 seconds to 1 minute. Be patient! Wait a minimum of 30 seconds to allow the modem memory to fully clear. 

  3. Plug the power cord back in and wait for the power light and internet light to turn green (or the C4000 single status light). It can take 3-5 minutes to fully boot back up.

How to reboot from My CenturyLink

With several of our CenturyLink modems, you can reboot from the app or website. If this option hasn't been added yet for your modem, it's coming soon!

You'll need to wait for a few minutes while the reboot completes. You can watch your modem lights or the internet/WiFi connection on one of your devices to know when your network is back up and running. 

Still have a poor connection after rebooting?

Check for firmware updates, as outdated firmware can also cause performance issues. If you're still having trouble, use Troubleshooter to remotely test your modem and your line, or run through our steps to troubleshoot your internet connection on your own.
