On this page I will be showing you how to properly reset the Dlink DMG-6661 router back to factory default settings. 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 device you take all the settings and return them all to factory defaults. This means any setting you have changed in the lifetime of this router is erased and returned to how it was straight from the factory.

Warning: Resetting any device has it's risks. Please be aware that problems do occur, especially if you are unaware of what settings will be changed and what ones will not be. Consider the following before you continue:

  • The router's main username and password are erased and need to be reconfigured after the reset is finished.
  • The Internet name and password are also reverted back to factory defaults.
  • If this is a DSL router you need to re-enter the ISP or Internet Service Provider username and password. Call your local ISP for the details.
  • Any other settings you have changed such as port forwards or IP Addresses are erased. We recommend writing these down so you remember to reconfigure them after the reset is finished.

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.

To begin you need to know where the reset button is located. We have found it for you on this particular model of D'link. It is found on the back panel of the device. Take a look at the image below.

This is the reset page from your Dlink DMG-6661 router.

Taking a straightened paperclip press and hold the reset button down for approximately 10 seconds. This will start the reset process which could take upwards of a minute or two.

Warning: Most router companies have a safety in place that if you don't hold the reset button down for long enough you end up only rebooting the device instead of resetting it.

Remember a factory reset like the one you are doing here erases every single setting you have ever changed during the lifetime of this device. If you want to try and avoid that you need to exhaust the other troubleshooting methods first.

Login to the Dlink DMG-6661

Now that you've reset your Dlink DMG-6661 router we suggest logging into it. This is done by using the factory default username and password. Not sure where to find these? We have them listed for you in our Login Guide.

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

Change Your Password

After you've logged into your router we recommend setting a new password for it. This password can be whatever you like, however keep in mind that a strong password consists of 14-20 characters and uses no personal information. For more help take a look at our Choosing a Strong Password Guide.

Tip: Afraid of losing your new password? Try writing it on a sticky note and attaching it to the bottom of your router.
