On this page I show you exactly how to reset a Linksys WRT55AG 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 unit only. No settings are changed in a reboot. When you reset a router you revert all changed settings back to how they were from the factory.

Warning: Settings are changed during a reset. Here is a partial list of some of the settings that will change:

  • The router's username and password.
  • The WiFi username and password.
  • Any port forwarding you have done or IP Addresses you have changed.
  • If this is a DSL router you need to re-enter the Internet Service Provider (ISP) username and password. Call your local provider for the details.

Reset the Linksys WRT55AG

Below is an image of the back panel of the Linksys WRT55AG router. I have circled the reset button for you in red. Note that the reset button is actually more of a pinhole. This is designed this way to avoid accidental resets.

First of all be sure the router is on during this process or it will not work.

Take a sharp object such as a sharpened paperclip and press down on the reset button for about 5 seconds. This begins the reset process. DO NOT INTERRUPT THE RESET. Doing so can cause permanent damage to the device.

Remember this reset is erasing every personal setting on the device. Make sure you have tried other troubleshooting methods before you continue with this reset.

Login to the Linksys WRT55AG

Now that the Linksys WRT55AG router has been reset you will be required to login to it by using the default login information. Here at we have found this information for you and included it in our Login Guide for the Linksys WRT55AG router.

Tip: Unable to login with the defaults? The router might have not been properly reset. Try resetting it again but this time hold down the reset button for a little longer.

Change Your Password

After you successfully login to the router you should change the password as soon as possible. The default password is easy to guess which makes it a terrible password. Try to make your new password unique. Visit our Choosing a Strong Password guide if you need help making a secure password.

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

Setup WiFi on the Linksys WRT55AG

Finally it is time to secure your wireless network. To accomplish this you will need to configure the router's WiFi settings. If you need help with this step be sure to check out our WiFi Instructions for the Linksys WRT55AG router.
