Why Tenda HTTPS Web Interface Is Detected As Unsecure by Some Web Browsers
Sometimes, we receive some feedbacks which are related to the security issue of Tenda web interface management via HTTPS. When customers enable Local Management via HTTPS option on Tenda router to stay extra safe, some web browsers still report Not Secure when accessing HTTPS Tenda web interface however. This article will explain why this happens with details.
The error message reported by some web browsers for Tenda https web interface would be like the following picture:
The reason why our browsers recognize tendawifi.com as “insecure” is that tendawifi.com’s Certificate is a self-signed Certificate. Most browsers do not accept this kind of Certificate because tendawifi.com is not an authoritative CA.
However, even if our self-signed Certificate is not trusted, the connection between your browser and the tendawifi.com server is secure.
A Certificate’s purpose is only to allow a client verify an unknown server. It has nothing to do with the encrypted connection. The data transmitted between the browser (client) and tendawifi.com (server) remains safe and encrypted. No one else could decrypt these data except the client and the server.

How to reset Tenda device to factory default
How to reset Tenda router to factory default/What should I do if I forget my WiFi password?
Long press the reset(RST) button (It’s on the back side of the router) like for 8-10s, then the LED will start to blink. It means you successfully get back to the factory default.
Notice:
1. A hard reset will restore your device to factory default settings. You should reconfigure the device from scratch or you can load the configuration file you have backed up before the reset.
2. For these models, we could see WPS/RST button on the rear panel/the Front Panel. To use WPS function, please push the button for less than 5 seconds, and then the WPS LED will flash; to reset the router, please push the button for at least 10 seconds.
There are two methods to reset to the Router’s factory defaults:
Method 1: Hard reset/By pressing the RST button
With the Router powered on, press and hold the WPS/RESET button (more than 10 seconds) until the SYS LED becomes quick-flash from slow-flash. Then release the button and wait the Router to reboot to its factory default settings.
By default, Tenda routers broadcast their network name (SSID) to make it easier for users to see and connect to the network. Otherwise, the users need to know the network name and manually connect to it. Disabling SSID broadcasting is a good way to reduce the risks of being an easier target of network intruders. You can choose to hide SSID to disable the SSID broadcasting.
Method 2: By Router’s Web Interface
Go to the router web UI configuration page, then go to More > System Settings > Backup & Restore > Reset page, then click on the Reset and wait the Router to reboot to its factory default settings.
Note:
1. Make certain that the router is powered on before it restarts completely.
2. The default IP address/domain name can be found at the bottom label of the product, and the default login username and password both are admin for older routers (all lower case), newer routers are longer this anymore.

How to find the hardware version on a Tenda device
For most of products
Turn over the device so you can see a label on the back or bottom of the unit. Look for a character string next to the serial number, the looks like: “V: X.X”. This is the hardware version of the device.
For products without labels:
The number at the end of the FCC ID indicates the hardware version. If there is no version number, like V7TRX12P, after the model number, that means it’s version 1.
For products with management interface:
Open a web browser and enter the domain name which can vary between units in the address bar. The address for your device can be found on the label on the back or bottom of the unit.
Below are the official domains currently in use:
Router – http://www.tendawifi.com
Range Extender – http://re.tenda.cn
There is a character string “Ver:X.Y” (for example, Ver:1.0) in the Serial Number field, and the number X is the hardware version of the device. If the string is “Ver: 1.1”, normally it means that the hardware version is V1. Different model has different management interface.
