For all versions of the Linksys WRT54G router, the default password is admin. The password is case-sensitive, so it must be written exactly as it is.

The default IP address is 192.168.1.1. This address gives you access to the router settings and options.

There is no default username for the WRT54G, so leave this field blank when logging in. This is also true for most other Linksys routers.

If the password on your Linksys WRT54G has been changed, the default password of admin will not work. If you do not know the password, reset the router to factory defaults. This will return the configurations to how they were when the router was first purchased, including the password.
