Connect your computer to your router's network, either wirelessly or via an Ethernet cable.
Open a web browser and type in the address bar. This should take you to the ASUSWRT Dashboard UI. If not, you can also try typing 192.168.1.1, which is the default IP address for most ASUS routers.
Enter your username and password to log in. The default username and password are both admin, unless you have changed them before.
You should now see the main page of the web management interface, where you can view and modify your router's settings.
How to Download the Latest Firmware Update from the ASUS Website

Save the firmware file to a location on your computer that you can easily find later. The file should have a .trx extension.

Go back to your router's web management page and click on Administration.
Select Firmware Upgrade from the menu on the left side.
Click on Browse and locate the firmware file that you downloaded earlier.
