What should you enable to hide your wireless network from users unless they knew its name?

Disabling SSID broadcast effectively hides the wireless network from casual users, as it prevents the network name (SSID) from being publicly advertised. When the SSID broadcast is disabled, the network does not appear in the list of available networks on devices searching for Wi-Fi connections. This means that only users who already know the SSID can connect, as they would need to input the network name manually to gain access.

In contrast, enabling SSID broadcast would make the network visible to anyone within range, which does not achieve the goal of hiding the network. Using hidden encryption or MAC filtering can enhance security, but they do not specifically address the visibility of the wireless network itself. Hidden encryption focuses on securing the data transmitted over the network, while MAC filtering restricts access based on device hardware addresses. These measures are beneficial for protecting the network but do not prevent it from being discovered in the first place.
