Here I will be explaining how to reset the Dlink DIR-451 router back to the original factory defaults.

Before I begin I need to explain the difference between a reset and a reboot. When you reboot a router you cycle the power to the device. This is either done inside the router's interface or manually. To reboot a router manually you unplug the power source, wait about 10 seconds, then plug the power back in. When you reset a router you completely erase every personal configuration you have ever made to the router.

Warning: Resetting a router is a big step in troubleshooting and should only be done after you have exhausted your other options. We highly recommend making a list of any settings you have changed during the lifetime of this router. Consider the following:

Reset the Dlink DIR-451

The first thing to do is locate the reset button. In this case it is found on the back panel of the device. See the image below, I have circled the reset button for you.

This is the reset page from your Dlink router.

Take the end of a paperclip and press down on the reset button for about 10 seconds. This begins the reset process. If you don't hold the button down for long enough you end up only rebooting the router instead of resetting it like you wanted.

Remember this reset erases every single setting you have ever changed on this device. If you want to avoid the loss this creates we strongly recommend trying other methods of troubleshooting.

Login to the Dlink DIR-451

Now that you've reset the Dlink DIR-451 router you'll need to log into it. Do this by using the factory default username and password. We have these listed for you in our Login Guide.

Tip: If the defaults aren't working for you try holding the reset button down for longer.

Change Your Password

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

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