Users are mostly recommended to perform the Firmware update process through the tplinkwifi.net window. A user has to visit the official support website of the Tp-link and has to download an available firmware version for his router. If your Tp-link router doesn’t support the cloud service, you won’t be able to perform the check online method of updating the firmware on your router. Make sure you download an appropriate firmware version for your router, as an incorrect firmware version could void the warranty of your product.
