To secure your home wifi, besides changing passwords regularly, another effective method is hiding your wifi name, also known as hiding the Router's SSID. With this method, when devices scan for wifi signals, your wifi won't appear in the list of available networks. The following article from Mytour guides you on hiding SSID on two popular wifi modem brands, TP-Link and Tenda, with similar steps applicable to other brands.
1. Hiding wifi on Tenda modem
Step 1: Open your browser and enter the IP address 192.168.0.1 to access the Tenda modem's management page. After accessing the address, log in with the password 'admin'.

Step 2: After successfully logging in, navigate to Wireless Settings, check the box for Hide WIFI, and press OK to save the settings.

2. Hiding wifi on TP-Link modem
Step 1: Log in to the management page using the IP address 192.168.0.1, and enter the credentials (admin) when prompted.

Next, uncheck the Enable SSID Broadcast option and press Save to complete the process.

So, we've successfully hidden the wifi. Now, how do you connect to a hidden wifi? Follow these steps.
3. Connecting to a Hidden Wifi
For smartphones, go to wifi settings, choose Add Network (the option may vary for different phones, possibly represented by a plus sign).
In the new window, enter the wifi network name in the SSID field, choose security type as WPA/WPA2 PSK, input the wifi password, and finally, press OK.

For Windows 7 laptops, click on the wifi icon in the taskbar and select Open network and sharing center.

In the new window, choose Set up a new connection or network.

Next, select Manually connect to a wireless network and press Next.

In the new window, follow these steps sequentially:
- Enter wifi name
- Choose WPA2-Personal security type
- Select AES encryption type
- Input wifi password
Check Connect even if the network is not broadcasting (important)
You should also check Start this connection automatically to let the computer connect to wifi automatically.
Finally, click Next.

If you're confident with the settings, press Close to complete.
