How to identify the version of ASUSwrt-Merlin Firmware?

Step 1: Log on to the ASUS RT router’s control panel by entering the router’s default address 192.168.1.1 to the address bar of your preferred browser. (If you change your router’s default IP address, enter that into your browser instead). While connecting using 192.168.1.1, the URL may change to router.asus.com due to the default DNS configuration specified in the router.

Step 2: Scroll down to the Administration tab.

Step 3: Click on the Firmware Upgrade tab and scroll down to reach the Firmware Version field under Firmware Version.
