Tenda D302 Firmware Update

Important Notes Before You Begin:

• Do not power off the device or disconnect the cable during the update.
• Do not use the wireless connection for the update; use a wired (Ethernet) connection.
• The firmware file is specific to the hardware version (e.g., V1.0, V2.0). Check the label on your device.
• Updating may reset settings to factory defaults — back up your configuration.
