On this page I will be showing you how to properly reset the Dlink DSL-2640B-SEA-1.00 router back to it's original factory default settings.

Before I do that I need to explain that a reset is not the same thing as a reboot. A reboot is a cycle in the power to the device. A reset is a complete wipe of all settings that have been changed. This means that when you reset a router, every single setting you have ever changed is erased and reverted back to factory defaults.

Warning: A reset could cause extra problems for you if you don't know what settings are erased and what ones have remained the same. We recommend making a list of all the settings you know about. Consider the following:

  • The main username and password used to access the Dlink DSL-2640B-SEA-1.00 web interface is reverted back to how it was from the factory.
  • The wireless information is also erased and reverted back to how it was when it was new.
  • If you use a DSL connection you need to re-enter the ISP (Internet Service Provider) username and password. Go ahead and call the ISP for all the details.
  • Have you made any other changes here? Have you forwarded any ports? Have you changed any IP addresses?

Reset the Dlink DSL-2640B

The first step in a reset is to find the reset button on the router itself. For this particular model you can find it on the back panel. I have circled it for you in the image below:

This is the reset page from your Dlink DSL-2640B router.

Take a unwound paperclip or similar object and press down on this reset button for about 8 seconds. When you release the reset button the reset process begins. This takes about 30 seconds. As a safety feature, a lot of routers set it up so that if you don't hold the button down for long enough you end up only rebooting the device instead of resetting it like you wanted.

Don't forget that a reset like the one you are preforming here is erasing every single personal setting you have ever changed on this device. This is why we strongly recommend exhausting any other methods of troubleshooting you may have at your disposal before continuing with a reset.

Login to the Dlink DSL-2640B

Once you've reset the Dlink DSL-2640B-SEA-1.00 router you'll need to log into it. Do this by using the factory default username and password. We have these both provided for you in our Login Guide.

Tip: Defaults not logging you in? Try holding the reset button for longer.

Change Your Password

Now that you've logged into your router we recommend setting a new password for it. This can be anything you want it to be, however keep in mind that a strong password if 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 sticky note and attaching it to the underside of your router.
