On this page I will describe how to properly reset the Linksys SPA-400 VoIP Gateway router.

There is a lot of confusion about the difference between a reset and a reboot. WHen you reboot a router you cycle the power to the unit. When you reset a router you take all the settings and return them all to factory defaults. This means every single setting you have ever changed is erased and returned to how it was from the factory.

Warning: Make sure you use caution when resetting a router. It is a big step and should not be taken lightly. I recommend making a list of all the possible settings you may of changed in the past. Consider the following:

  • The router's main username and password will be erased and returned to how they were from the factory.
  • Any port forwarding you have done is lost.
  • IP addresses that have been changed will need to be reconfigured.
  • Parental controls, DNS, etc... are all erased during a reset.

In the image below I have circled the reset button for you in red. Notice that this reset button is more of a pinhole.

While the device remains on take a bent paperclip or similar object and press down on the reset button for approximately 10 seconds. This starts the reset process. If you don't hold the reset button down for long enough you might end up only rebooting the router instead of resetting it like you wanted.

Warning: DO NOT unplug or turn off the router during the reset process. Doing so could cause permanent damage to the device.

Remember a reset like the one you are about to carry out will erase every single setting you have ever changed. I strongly recommend exhausting your other troubleshooting options first.

Login to the Linksys SPA-400

Now that the router has been reset you need to login to it using the default IP address, username, and password. This login information has been found for you and compiled in our Linksys SPA-400 Login Guide.

Tip: Defaults not working? You may have not held down the reset button for long enough during the router reset.

Change Your Password

Once you successfully gain access to the router you should consider changing the password as soon as possible. Default passwords are easy to guess and can leave your router at risk. If you need any help getting started on making a secure password, visit our Choosing a Strong Password guide.

Tip: Want to avoid losing your password? Try writing it down on some paper and attaching it to the base of the router.
