If you need to reset your Cisco DPC3941B router back to factory settings, then this article shows you how. A router reset is a much bigger deal than a router reboot. Unplugging a router from the wall reboots it. 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. The following settings in your router will be changed:

  • The router's login and password are reset.
  • All WiFi information such as network name, password, and authentication method are erased.
  • Your ISP settings are reset, which means you will have to contact your ISP to get them back.
  • All parental controls, firewall settings, and 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.

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.

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

Yours may look slightly different, but they are usually tiny. You may need a paper clip to push the reset button.

Watch the front panel lights while you hold the reset button down for at least 10 seconds. The blinking pattern of the lights on the front of the router should change when 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.

Keep in mind that this will completely reset your Cisco DPC3941B router.

Only take this last step of fully resetting your router after you have exhausted all other troubleshooting options, such as running our Router Password Finder software, which can recover a lost router password for you.

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. 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 is a huge security risk to leave your router's password set to the factory default. 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.
