The default Linksys WRT120N password is admin, which is the same password used by most Linksys routers. As with most passwords on not only routers but also websites and elsewhere, the WRT120N default password is case sensitive (that is, admin shouldn't have any uppercase letters).

Although some routers require a default username that must be entered along with the password, the WRT120N username field can be left blank; only the password is required. Just ignore the username field when logging in.

The WRT120N default IP address is This is the address that devices connected to the network use to access the router and the internet. It's also the IP address that's used as a URL to open the router settings.

Does the WRT120N Password Not Work? Here's What to Do

While the default username and password for the WRT120N works with the router out of the box, this default information can be changed from the router settings, which may be why you can't access the router. If you can’t log in to the Linksys WRT120N with the default credentials, reset the router to reapply the default settings and reinstate the admin default password.

To reset a Linksys WRT120N router:

  1. Turn the router around so you can see the plugged-in cables and the Reset button.

  2. With a small object such as a paperclip or pin, press the Reset button for approximately 5 seconds.

  3. Remove the power cable from the back of the WRT120N for a few seconds, then plug it back in.

  4. After waiting approximately 1 to 2 minutes for the router to power on fully, be sure the network cable coming from the computer is still attached at the back of the router.

  5. Use the default IP address to connect to the router with the default password of admin.

  6. Change the router’s default password to something more complex than admin. Then store this information in a secure, free password manager.

Resetting a router removes all the custom settings that were configured, which means all custom network settings such as the SSID, network passwords, and guest network configurations will need to be reentered.

If you just need to restore the default settings and know your password, log into the setup page and go to Administration > Factory Defaults.

How to Back up the WRT120N Router Settings

After setting up the router once again with your custom preferences, make a backup so you can restore the configurations if the router is reset again in the future.

To do this, go to the Administration > Management page and select the Backup Configurations button to create the backup file. Restoring the settings is as easy as uploading the backup file with the Restore Configurations button on the same page.
