How to Reset the Dlink DSL-504T

On this page I will be showing you how to reset the Dlink DSL-504T 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 take every single setting you have ever changed and return them all back to the original factory default settings.

Warning: Resetting this router is a big step and should not be taken lightly. We suggest making a list of all the settings you have ever changed on the Dlink DSL-504T. We started the list for you:

Reset the Dlink DSL-504T

The first step in this reset is to find that tiny button/pinhole that calls itself a reset button. On this particular model of D'link you can find it on the back panel. Take a look at the image below.

You need to take a straightened paperclip and press down on the reset button for at least 10 seconds. This starts the reset process. Be careful that you don't simply press and release the reset button, that typically will cause a reboot instead of a reset.

Don't forget that a reset is going to erase every single setting you have ever changed on this device. If you need to avoid this loss we highly recommend you figure out a different way of fixing the problem you are having with this Dlink DSL-504T.

Login to the Dlink DSL-504T

Now you'll need to log into your Dlink DSL-504T router. This is accomplished by using the factory default username and password. Not quite sure where to find these? Not to worry. We have provided them for you in our Login Guide.

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

Change Your Password

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

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