How can I change my Asus router password?

Whenever new firmware is available for the ASUS router, a notification will get popped up on the router.asus.com basic Homepage. You can directly update the firmware from the web interface of an ASUS router. Make sure you have read the guidelines before updating the firmware of a router. Users must create a backup of the current configuration through the web interface of the ASUS router. Sometimes the configuration gets erased after the update process which causes trouble in configuring the router again.
