1. What if my uploading a setting file fails?

  • Please try to upgrade the latest firmware version and configure new settings. Do not restore the router to its default settings.


2. What if I can't enter the web UI to restore my router after uploading a setting file?

  • You can push the RESET button on your router. (See image below)


        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 not be on at this time. It is normal due to the router restarting.

         Wait for the LED lights to turn on again and try to login to the Web UI.

         If there still have issue, it is recommended that you try a hard factory reset. Please refer to [Wireless Router] ASUS router Hard Factory Reset for more details.
