The factory reset process is the most utilizing process as the user could use it in case he forgets the password and wants to log in to the dlinkrouter.local window. After restoring the device into the default setting, the user could apply the new password and user to the login window of the Dlink router. After the reset process, the user has to use the default username and the password of their router.
