If a user wants to update a firmware using the automatic method, he has to make sure that his Tp-link router supports the cloud service. If tplinkwifi.net doesn’t support the cloud service, you can’t apply the automatic method for the update process, you have to update it through the manual process. To download new firmware for your router, you need a hardware version and a model version of the Tp-link router. Wrong firmware may void the warranty of your device or may permanently damage it.
