On this page I will be showing you how to reset the Dlink DIR-855 router back to factory defaults. This is not the same thing as a reboot. When you reboot a router you are simply cycling the power to the device. When you reset a router you erase every single setting and return them all to factory defaults.

Warning: Resetting this router can cause additional problems for you if you are not expecting them. Consider the following:

  • The router's interface username and password are erased. Forgetting one's password and/or username is the number one reason for a reset. Just about everything else can be fixed from inside the router's interface.
  • The Internet name and password are also erased. These need to be reconfigured after the reset process is complete.
  • If you use a DSL, you need to re-enter the ISP (Internet Service Provider) username and password to be able to use the Internet again after the reset. To learn more call your ISP.
  • Have you made any other changes to your device? Things you may have forgotten include any parental controls you have in place or port forwards. Don't forget these are erased as well and need to be reconfigured 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 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.

Find the reset button on the back panel of the device. I have circled it's location for you in the image below.

This is the reset page from your Dlink DIR-855 router.

Taking a pen or very sharp pencil press and hold the reset button for about 10 seconds. This starts the reset process. If you don't hold the reset button down for long enough you end up only rebooting the device instead of resetting it like you wanted.

Remember resetting a router erases all personal changes you have ever made. If you want to try and avoid this we highly recommend trying other methods of troubleshooting first.

Login to the Dlink DIR-855

After resetting your Dlink DIR-855 router you'll need to log into it. This is done by using the factory default username and password. Don't know where to get 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 for long enough.

Change Your Password

Once you've reset and logged into your router we suggest setting a new password for it. This can be anything you want it to be, however keep in mind that a strong password consists of no personal information and is 14-20 characters in length. For more help check out our Choosing a Strong Password Guide.

Tip: To keep from losing your new password try writing it on a sticky note and attaching it to the bottom of your router.
