If you need to reset your Cisco DPC3941T router back to factory settings, then this article shows you how. Resetting a router is different than rebooting a router. A reboot happens every time a router loses power. However, when you reset a router you, return it back to its factory default settings.

Warning: Before you continue, there are a few things you need to know. The following settings will be changed in your router:

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

A router reset should be considered the last resort when you cannot log in to your router any other way. You should be sure that you have tried to at least recover your router password using our Router Password Finder before resorting to a router reset.

Use a VPN Instead

Have you considered using a VPN instead of forwarding a port? For most users, a VPN is a much simpler and more secure choice than forwarding a port.

We use and recommend NordVPN because not only is it the fastest VPN, it includes a new feature called Meshnet that makes forwarding a port no longer necessary for most applications. With NordVPN Meshnet, you can connect to your devices from anywhere in the world, completely secure, over a highly encrypted VPN tunnel.

When shopping for a VPN, make sure that they meet the following criteria:

  • Your VPN provider should have a no-logs policy. This means that they do not keep any logs of any kind.
  • Make sure that your VPN provider has lots of exit nodes all around the world.
  • Check that your VPN will not affect your speed.
  • Verify that your VPN provider uses WireGuard as the underlying protocol.
  • Many people prefer a VPN provider that is not based in the United States.

This is the list of requirements that we used when we were shopping around for a VPN provider. There are lots of free, shady VPN providers out there that we looked at and dismissed.

Based in Panama, using diskless servers, and with over 6,100 servers in 61 countries, we can safely say that NordVPN satisfies all of these requirements.

NordVPN is the fastest VPN!

Once you've set up your NordVPN account on multiple computers and enabled Meshnet, you can seamlessly access all of your devices as if they were on the same network. You don't even have to log in to your router. It's very simple.

Every time you click on one of our affiliate links, such as NordVPN, we get a little kickback for introducing you to the service. Think of us as your VPN wingman.

Recover Password in Cisco DPC3941T

Instead of resetting your router back to factory settings, you may want to try running our Router Password Finder first.

Router Password Finder can save you a ton of time by recovering your lost or forgotten router password instead of doing a full router reset.

Router Password Finder - Recover Lost or Forgotten Router Passwords

Only after you have tried to recover your missing router username and password should you perform a full router reset.

Usually there is a reset button located on the back or bottom of a router. This is what a typical reset button looks like:

Router Reset Button

Even though yours may look slightly different, you need to look for a tiny button. You might find a pinhole on the back of the router that requires a paper clip to push the button hidden under it.

Watch the front panel lights while you hold the reset button down for at least 10 seconds. After a few seconds the lights should blink differently. When this happens, the reset is complete. You cannot hold the button too long, and it will not hurt the router to hold the reset button down for longer than 10 seconds.

Don't forget, this step will totally reset your Cisco DPC3941T router back to factory settings.

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 DPC3941T

Now that you have finished resetting the router, you need to login to the router interface using the default username and password. We have a DPC3941T Login Guide with all this information ready for you.

Change Your Password

Be sure to change your router's default password after you get logged back in. The factory default passwords for routers are very well known. Our Choosing a Strong Password guide talks about choosing a strong password for your router.

Tip: Put your new password on a post-in note and stick it to the bottom of your router.
