Like most Linksys routers, the Linksys WRT120N default password is admin. 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.
Information in this article applies specifically to the Linksys WRT120N router. Linksys router passwords are always case-sensitive.
What Is the WRT120N Default Gateway?
The default gateway is the IP address that devices connected to the network use to access the router and the internet. The default IP address for the WRT120N router is 192.168.1.1. You can enter the IP address as a URL in a web browser to open the router settings.
You can find the default gateway IP address of any device in the Windows network settings.
Why Is the WRT120N Default Password Not Working?
While the default 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 default password.
How to Reset the WRT120N Password
To reset a Linksys WRT120N router:
Turn the router around so you can see the plugged-in cables and the red Reset button.
Use a paperclip or pin to press the Reset button for approximately 5 seconds.
Remove the power cable from the back of the WRT120N for a few seconds, then plug it back in.
Wait for 1-2 minutes for the router to power on fully, then make sure the network cable coming from the computer is still attached at the back of the router.
Enter the router's default IP address (192.168.1.1) into a web browser and log in with the default password (admin).
Change the router's default password to something more complex. Follow best practices for creating a strong password.
You can store your online login credentials with a free password manager.
Resetting a router removes all the custom settings that were configured. Therefore, 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 find your password, log in to the setup page and go to Administration > Factory Defaults.
How to Back Up the WRT120N Router Settings
After setting up the router with your custom preferences, make a backup so that you can restore the configurations if the router is reset again in the future.
To do this, open the router settings and go to Administration > Management, then select Backup Configurations. A file will be generated, which you can upload by selecting Restore Configurations on the same page to restore your settings at any time.
