Visit the Tenda D305 Support Page to find the latest firmware version.

Use a wired connection: Always perform firmware updates using an Ethernet cable connected directly from your computer to the router. Updating over Wi-Fi can lead to failure and "bricking" the device if the signal drops.

Backup your settings: Firmware updates often reset the router to factory defaults, erasing your Wi-Fi name and passwords.  3. Perform the Update 

Access the Admin Page: Open a web browser and enter 192.168.0.1 or tendawifi.com.

Login: Use your admin credentials (default is typically admin for both username and password if not changed). Navigate to Upgrade: Go to Maintenance > Firmware Update. Alternatively, look under System Tools > Upgrade. Updating the Tenda D305 firmware, usually via manual

2. Release it. The router will reboot.
3. Log back into 192.168.1.1 (default password: admin).

• Crucial: Do not unplug the router or close the browser.
• The router will reboot automatically. This process usually takes 2 to 5 minutes.
• You will see a progress bar or a countdown.
• Once the reboot is complete, the LED lights on the router will stabilize.
