The Huawei B683 is a rugged, versatile 4G LTE router, often used in industrial IoT, marine environments, remote offices, and high-demand home networks. Its ability to convert a 4G signal into stable Wi-Fi and Ethernet makes it a favorite among users who need reliability over flashy features.

Since the Huawei B683 does not support 4G networks, it was likely phased out from official support years ago. If you are looking for a firmware update specifically from the year 2021, you should manage your expectations. The device's last official updates were likely released much earlier.

Ensure your router is plugged into a stable power source. Never turn off the router during the update process.
