On this page I will discuss how to reset the Cisco DPC3828D router back to it's original factory default settings. This is not the same as a reboot. A reboot turns off the router and restarts it cycling the power to the device. A reset is taking all the settings and returning them to factory defaults.

Warning: Resetting the router can cause issues if you aren't expecting your personal settings to change. We recommend making a list of all the settings you know will be changed. We have started this list for you.

  • The Internet name and password
  • The ISP username and password if you use a DSL router. These can be gotten from your Internet Service Provider.
  • The router setup username and password
  • Write down any other setting you have changed. This would include any personal changes you have made. Write down any port forwards you have done or IP addresses you have assigned.

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.

Once you have decided to reset the router you need to know where the reset button is located. On this particular router it can be found on the back panel. We circled it in the image below.

This is the reset page from your Cisco DPC3828D router.

Notice how tiny and recessed the reset button is. This is to avoid accidental resets. Take the end of an unwound paperclip and press down on the button for a minimum of 10 seconds. This starts the reset process. If you only press and release the button it will only reboot the router instead of resetting it like you wanted.

Please remember that this reset is going to erase every setting you have ever changed on this router. If you want to avoid losing all your personal setting we highly recommend you try other methods of troubleshooting before you decide to reset.

Login to the Cisco DPC3828D

The next step is to login to the Cisco DPC3828D router. You need the default IP address, username, and password. We have found this information for you and included it in our Login Guide for the Cisco DPC3828D router.

Change Your Password

It's a good idea to change the router's setup password after you use it for the first time. Default passwords are very easy to guess making them very bad passwords. If you need help coming up with a new password, check out our Choosing a Strong Password guide. It is full of ideas and tips in making a strong password.

Tip: Of all the information you change, the router's IP address, username, and password are the most important when it comes to not losing them. Any other values if lost can be found by accessing the router setup pages. But to access those router setup pages you need to know the router's IP address, username, and password. If this router is located in your home we recommend writing this information on a sticky note and attaching it to the underside of the router for next time.

Setup WiFi on the Cisco DPC3828D

Now you should check the WiFi settings. The SSID, Internet password, and security mode are all reset. Some routers like to leave the security wide open as the default meaning there is no security at all. Make sure your security mode is set to WPA2 along with a strong Internet password. If you need additional help with this take a look at our How to Setup WiFi on the Cisco DPC3828D guide.
