: Firmware files are specific to hardware versions (e.g., V3.0, V4.0). Using the wrong one will damage the device. Step 1: Identify Your Hardware and Current Firmware

: Always connect your computer to the router via an Ethernet cable . Do not upgrade over Wi-Fi, as a connection drop during the process will fail the update.

To find the correct update file, you must first know your router's current status. Connect your computer to a LAN port on the Tenda F3.

: Ensure the router is plugged into a stable power source. Do not power off the device during the upgrade.
