Verify the Version: Log back into the interface (192.168.1.1) and check the System Tools > Firmware Update page to ensure the "Current Version" matches the version you just installed.
Reconfigure Settings: Sometimes updates reset the router to factory defaults. If this happens, you will need to re-enter your ISP username/password (PPPoE settings) and your Wi-Fi name and password.
Speed Test: Run a quick internet speed test to ensure your connection is stable and performing as expected.

Cause: You downloaded firmware for D301 V1 or a different model.
Fix: Redownload explicitly for V2. Clear your browser cache and try again.

Where to Download the Legitimate Firmware

Do not download firmware from random forums or file-hosting sites. Only use official sources.

Go to the official Tenda support website: https://www.tendacn.com/en/support/download-cata-1.html
In the search box, type "D301 v2" .
Select "D301 v2 (ADSL2+ Modem Router)" from the dropdown.
Look for the latest firmware file. Typically, the filename format is something like D301 v2_VXXXX (Build XXXX)_US or TENDA_D301 v2_BRIDGE_XXX.
Check the release date and changelog. If the file is older than 2020, your router may be end-of-life, but update anyway to the latest version available.
Download the .bin, .trx, or .zip file. If it is zipped, extract the actual firmware image (e.g., d301_v2_firmware.bin) to your desktop.

Note: Tenda has regional websites (US, EU, Asia). If you have an international version, the US site usually has the most universal firmware.
