This guide will show you how to reset the Cisco DPC3925 router to it's original factory settings. This is not the same thing as a reboot. A reboot is a power cycle for the router. A reset is taking all the settings and returning them all to factory defaults.

Warning: This reset can cause even more problems for you if are not expecting all the settings to be erased. Please take note of the following things:

  • If you use a DSL router you will need to re-enter the ISP username and password in order to continue to use the Internet. To find out what the correct username and password are you will need to call your Internet Service Provider.
  • The router's setup username and password are reverted to factory defaults.
  • The Internet name and password are reverted as well.
  • Any other settings you have changed in the past will be erased. Think about whether you have ever forwarded a port or changed an IP address.

Use a VPN

Have you considered using a VPN when you connect to the internet? A VPN is a great way to increase your security and anonymity while surfing.

We use and recommend NordVPN because not only is it the fastest VPN, it includes a new feature called Meshnet that makes securely sharing your home network super simple. 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 birthday 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.

Now you need to find that tiny recessed reset button. For this particular router it is on the backside of the router. See the image below.

This is the reset page from your Cisco DPC3925 router.

Due to the size and recessed nature of the button you need to use an unfolded paperclip and press down on the button for about 10 seconds. If you don't hold the button down for the entire amount of time it will only reboot the router instead of the desired reset.

Remember this reset is erasing every setting you have ever changed on the device. If you want to try and avoid having to reconfigure the device you should try other troubleshooting methods first.

Login to the Cisco DPC3925

Now you need to login to the Cisco DPC3925 router. To do this after a reset you need to know the default IP address, username, and password. These are in our Cisco DPC3925 Login Guide.

Change Your Password

After you finish logging into the Cisco DPC3925 router you should change the router password. Default passwords like that one are meant to be easy to guess which makes it a very bad password. Create a new one using our Choosing a Strong Password guide to help you.

Tip: Don't lose this information. If you keep your router in your home it's okay to write it down on a piece of paper and attach it to the underside of the device for next time.

Setup WiFi on the Cisco DPC3925

Now you need to check on the wireless settings. The security should be set to WPA2 along with a new complex Internet password. If you need further instructions we have created a guide titled How to Setup WiFi on the Cisco DPC3925.
