For all versions of Linksys WRT54G default password is “admin”. The WRT54G password is case sensitive.
WRT54G default IP address is 192.168.1.1. This is through the address that you are able to access the router’s settings and options.
There is no default username for WRT54G, which means that you can completely empty this field while logging in and leave it.
If the password on your Linksys WRT 54G has ever been changed (which is a good thing!) Then the administrator’s default password will not work. This “backup” password or nothing like it.
In this case, your best bet is to reset its WRT54G router to its factory default settings, which will restore all the configurations during the router that was bought for the first time.
Here’s how to reset a Linksys WRT54G router:
01- Turn the WRT54G around so you have access to the back of the router.
02- Hold down the Reset button. You may need to use a pen or other small, pointy object to access it.
03- Release the reset button after holding it for at least 30 seconds.
04- Unplug the WRT54G for a few seconds and then plug it back in.
05- Wait 60 seconds, giving the router time to boot up.
06- Connect the WRT54G router to your computer via a network cable.
07- Connect to the router using its default IP address, 192.168.1.1, and enter the default password of admin.
08- Change the default router password from admin to something more secure. Be sure to take note of the password this time! Storing it in a free password manager is a good idea.
Now that you have reset the router, you have to set up a wireless network again, as well as have to reconfigure any other settings you’ve already set up. It includes anything from a wireless password and any custom DNS server configured with the name of the network, static IP addresses, port forwarding rules, etc.
When finished, I recommend using the built-in feature under the Admin> Backup Configuration menu to back up the configuration. In this way, if you ever want to reset the router again, you can easily restore them.
