The default Linksys WRT120N default password is “admin”, which is the same password used by most Linksys routers. WRT120N default password is case-sensitive (i.e. the admin must not have any uppercase letters), not only with router but with most passwords in websites and elsewhere.
Although some routers require a default username that must be entered with a password, the WRT120N user name field can be left blank – only password is required. Ignore the username field while logged in.
WRT120N default IP address is 192.168.1.1. This is the address that the network-connected device router and ultimately use to access the Internet. This IP address is also used as the URL to open the settings of the router.
While the default username and password already specified for WRT120N works with the router outside the box, anyway, it can be changed from within the router’s settings, which means that you have forgotten what you did to them has changed.
If you think that you cannot log into Linksys WRT120N with those credentials, you can always reset to the default settings and reset the router to restore the administrator’s default password.
Here’s how to reset a Linksys WRT120N router:
01-The Reset button is at the back of the router, so turn the whole thing around so you can see all the plugged in cables.
02-Using a small object, like a paperclip or pin, hold down the Reset button for 10-15 seconds.
03-Now remove the power cable from the back of the WRT120N for a few seconds and then plug it back in.
04-After waiting a good 60 seconds, time for the router to power on fully, be sure the network cable coming from your computer is still attached at the back of the router.
05-Use the default http://192.168.1.1 IP address to connect to the router with the default password of admin.
06-Don’t forget to change the router’s default password to something more complex than admin. If you’re afraid you might forget the new password, you can store it in a secure, free password manager.
This means that you have to reconfigure all your custom network settings such as your SSID, network password, guest network configuration, etc.
