This article covers how to reset the Cisco DPC3941B router back to factory default settings. This is not the same thing as rebooting a router. Every time your router loses power it reboots. Resetting a router erases all settings from it and returns it to factory defaults.

Warning: Proceed with caution; resetting your router can be a major headache. When you reset your router, the following will happen.

  • The router's login credentials are reset.
  • All WiFi settings are reset, including network name and password.
  • If your router has any ISP settings they will be removed, and you will have to contact your ISP.
  • Any port forwards, firewall settings, or parental controls that you have configured will be removed.

Resetting your router should be considered the last step. Before you reset your router, you may want to try recovering your router password with our Router Password Finder.

Router Password Finder - Automatically Recover Lost or Forgotten Router Passwords

If you are unable to recover your lost router password, then you may have to proceed with a full router reset.

Reset the Cisco DPC3941B

Most of the time you can find a small reset button located on either the back or the bottom of a router. Look for something that looks like this:

Router Reset Button

Your reset button may look different, but usually they are very small. Sometimes the reset button is under a pinhole on the back of the router, and you need a paper clip to push it.

Hold the reset button down for 10 seconds and watch the lights. The lights on the front of the router should do something different when the reset happens. Keep holding the button as long as you want, it will not hurt anything to hold it down too long.

Remember, this will erase everything you have previously done to this Cisco DPC3941B router.

Be sure to only reset your router if you have tried everything else, such as running our Router Password Finder software, which can find your lost or forgotten router password for you.

Login to the Cisco DPC3941B

Now that you have finished resetting the router, you need to login to the router interface using the default username and password. Our DPC3941B Login Guide has all of the information that you need.

Change Your Password

Be sure to change your router's default password after you get logged back in. It's a very bad idea to leave your router's password set to the factory default. Our Choosing a Strong Password guide can help you pick a strong password for your router.

Tip: A great place to write your new password down is on a piece of paper taped to the bottom of your router.
