On this page we will explain how to reset the Dlink DSL-3780 router back to factory defaults. This is not the same thing as a reboot. When you reboot a router you cycle the power to the device. When you reset a router you erase every setting you have ever changed on this device.

Warning: Resetting this device is a big step and should not be taken lightly. We recommend making a list of all the settings you know of that will be changed. Included in that list should be:

  • The router's main username and password.
  • The Internet name and password.
  • If this is a DSL router you need to re-enter the ISP username and password. Call your ISP (Internet Service Provider) for the details.
  • If you have ever made any other changes to this device you need to write them down so you can reconfigure them later.

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.

Now that you have decided to reset the Dlink DSL-3780 router you need to find the reset button. Taking a look at the image below you can see that it is found on the back panel of the unit.

This is the reset page from your Dlink DSL-3780 router.

Take a straightened paperclip and press down on the reset button for about 10 seconds to reset the router back to the original factory defaults. If you only press and immediately release this tiny button you might only reboot the router instead of resetting it like you wanted.

Remember a factory reset like the one you are planning on doing is going to erase every single setting you have ever changed. To prevent this loss we highly recommend trying other methods of troubleshooting before you continue.

Login to the Dlink DSL-3780

After you've successfully reset your Dlink DSL-3780 router you'll want to log into it. Do this by using the factory default username and password. Not sure where to get these? Not to worry. We have them listed for you in our Login Guide.

Tip: If the defaults aren't logging you in it might be because the reset button wasn't held down for long enough.

Change Your Password

Now that you've logged into your router we recommend setting a new password for it. This can be whatever you want it to be, however remember that this password will only protect your router settings, not your wireless network. Still, setting a strong password is always a good idea. For help in doing so be sure to check out our Choosing a Strong Password Guide.

Tip: Prevent yourself from losing your new password by writing it on a sticky note and attaching it to the bottom of your router.
