Beware of public WiFi networks

Usually many people have a habit of using public Wi-Fi networks to access the Internet. Taking advantage of this vulnerability, hackers can create fake Wi-Fi networks for users to connect to, then hackers access users' systems, and steal important information.

My advice is that before using any public Wi-Fi network, you should double-check that the WiFi network is safe or not.

Disconnect Wifi

If there is no need to use Wifi, it is better to turn off Wifi.
