If you need to reset your Cisco DPC3828S router back to factory settings, then this article shows you how. This is not the same thing as rebooting a router. Turning a router off and back on again causes a reboot. This is different from a reset because a reset completely erases all settings from the router.

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

  • The router's login and password are reset.
  • Your WiFi name and password are reset.
  • Your ISP settings are reset, which means you will have to contact your ISP to get them back.
  • Any firewall settings, parental controls, or port forwards that you have configured 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. Before you reset your router, you may want to try recovering your router password with our Router Password Finder.

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 faster than ever deal!

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.

On most routers you can find a small button on the back or the bottom labeled reset. A typical reset button looks like this:

Router Reset Button

Even though yours may look slightly different, you need to look for a tiny button. Sometimes the reset button is under a pinhole on the back of the router, 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. After a few seconds the lights should blink differently. When this happens, the reset is complete. Keep holding the button as long as you want, it will not hurt anything to hold it down too long.

Just don't forget that this will totally reset your Cisco DPC3828S 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 DPC3828S

Now that you have finished resetting your router, you need to log in using the default username and password from the factory. We have a DPC3828S Login Guide with all this information ready for you.

Change Your Password

After logging in, you should really change your router's password for added security. Leaving a router password set to default is a very serious security risk. 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.
