[Wireless Router] I cannot log in to my ASUS router's web GUI using my username and password

If you encounter the following three circumstances, please reset the router into default setting and then set the password again. Once you have changed the username/password of WEB GUI , we will not know what password is.

A. When you can’t login to WEB GUI by your username and password.

B. When you forget or don’t know the username and password of WEB GUI.

C. When you find out that you had entered the wrong username or password, like the following picture :

You can try the following steps to set up the username and password again, and then try to login the WEB GUI.


1. Reset the router into factory default setting:

Note: All the settings (including internet settings) in your router will be removed. We suggest you ask your ISP for the related information of connecting to the Internet and then do following steps.

Please find the RESET button on your router like the below picture:

As for the following picture, we take [RT-AC66U B1] as an example.

 (Different models might have slight differences. If you have any question, please check the user manual)

Then press and hold the RESET button for 5-10 seconds until your power LED light starts to flash.

None of the LED lights should be on at this time. It is normal due to the router restarting.

Wait until the LED lights turns on again as the below picture, and it means that the reset completes.

If you can't use the RESET button to make the router reset to factory default settings, we would suggest you try Hard Factory Reset. For more details, you can refer to ASUS router Hard Factory Reset


2. Connect your computer to the router via wired or WiFi connection and enter your router LAN IP or router URL https://www.asusrouter.com to the WEB GUI.

    Note: Please refer to How to enter the router setting page(Web GUI) to learn more.
