To update the firmware of your Tenda D301 v4 N300 Wi-Fi ADSL Modem Router, you must manually download the correct file from the official Tenda website and upload it via the router's web interface. Prerequisites Before Updating
Check Current Version: Log in to your router (usually at 192.168.1.1 or 192.168.0.1) and find the "System Version" or "Firmware Version" under System Status to ensure you aren't already on the latest build. Wait 2–4 minutes
Hardware Match: Confirm your device is specifically the v4.0 hardware version. Installing firmware for a different version (like v1 or v2) can permanently damage (brick) the device.
Wired Connection: Always use an Ethernet cable to connect your computer to the router during the update. Updating over Wi-Fi is risky as a signal drop can corrupt the installation. Step-by-Step Update Guide

Wait for Reboot: The router will process the update and automatically reboot. Do not turn off the power during this process, which usually takes 2–5 minutes. Post-Update Tips
