The Chinese model of the Tenda AC23 router is identifiable by a single LED on the top cover, unlike the global version which has five LEDs. The Chinese model uses a firmware that is in Chinese, but it can be switched to English or other languages.
Press and hold the reset button for 10 seconds, then let go. The router will restart and revert to its factory settings.
Alternatively, you can reset the router through the web interface: Navigate to http://tendawifi.com, select "System Settings", then "Reboot & Reset", and finally click on "Reset".
You can install the US_AC23V1.1re_V16.03.09.17_multi_TDE01.bin firmware.
Or, you can download it from the official Tenda website:
