This is the reset guide for the Cisco DPC3941B router. Resetting a router is different than rebooting a router. Unplugging a router from the wall reboots it. Resetting a router erases all settings from it and returns it to factory defaults.

Warning: This is not a step to be taken lightly. The following settings will be changed in your router:

  • The router's login credentials are reset.
  • All WiFi information such as network name, password, and authentication method are erased.
  • Your ISP username and password will be reset, and you may have to contact your ISP.
  • Any parental controls, firewall settings, or port forwards will be removed.

A router reset should be considered the last resort when you cannot log in to your router any other way. Before you reset your router, you may want to try recovering your router password with our Router Password Finder.

Recover Password in Cisco DPC3941B

If the only reason that you are resetting your router is because you forgot your router password, then you may want to try running our Router Password Finder instead of resetting your router.

Router Password Finder is designed from the ground up to help you recover your forgotten router username and password, which can save you a lot of time.

Just keep in mind that a router reset should be done as the last resort when you are unable to login to your router.

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 at your router and try to find something that looks like this:

Router Reset Button

Reset buttons are usually tiny. Yours may look slightly different than this. Sometimes the button is under a pinhole, and you need a paper clip to push it.

Keep an eye on the lights on the front of your router while holding the reset button down for about 10 seconds. You should notice that the blinking pattern of the lights on the front of the router changes after a few seconds. Do not worry about holding the button down too long; this is harmless.

Remember, this will totally reset your Cisco DPC3941B router.

This last step should only be taken if you have tried everything else, such as using our Router Password Finder software, which can recover lost or forgotten router passwords.

Login to the Cisco DPC3941B

Once the reset is complete, you need to login to your router using the default IP address, username, and password. We have a DPC3941B Login Guide with all this information ready for you.

Change Your Password

After logging in to your router for the first time, you need to change your router's password. 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: Write your new password down on a post-it note and stick it to the bottom of your router.
