If you need to reset your Cisco DPC3941T router back to factory settings, then this article shows you how. A router reset is a much bigger deal than a router reboot. Rebooting a router is simply turning it off and back on again. This is very different from a reset, which erases a router completely and returns it to factory default settings.

Warning: Proceed with caution; resetting your router can be a major headache. A router reset will affect the following settings:

  • The router's login credentials are reset.
  • All WiFi login information and network names are reset.
  • All ISP settings will reset to default, and you may have to contact your ISP.
  • All parental controls, firewall settings, and port forwards will be removed.

Since a router reset is such a drastic step, it should only be done as a last resort when you cannot recover your router's password using any other methods. Make sure that you have tried to recover your router password using our Router Password Finder first.

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.

There is usually a small reset button located on either the back or the bottom of a router. This is what a typical reset button looks like:

Router Reset Button

Yours may look slightly different, but they are usually tiny. Sometimes the button is under a pinhole, and you need a paper clip to push 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 can hold the button down as long as you like, it will not hurt anything.

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 your router, you need to log in using the default username and password from the factory. Just follow our DPC3941T Login Guide to find all of the information that you need.

Change Your Password

After logging in to your router for the first time, you need to change your router's password. The factory default passwords for routers are very well known. You can follow our Choosing a Strong Password guide to help you pick a solid password for your router.

Tip: After creating this new password, we highly recommend writing this down on a post-it note and attaching it to the bottom of your router for future reference.
