What is the best option for preventing users from seeing each other on a WiFi network?

The best option for preventing users from seeing each other on a WiFi network is client isolation mode. This feature, when enabled on a wireless access point, ensures that devices connected to the same network cannot communicate directly with each other. This is particularly useful in public WiFi settings, such as cafes or airports, where maintaining user privacy and security is important. By isolating clients, it helps to prevent potential eavesdropping on data or malicious activities between connected devices.

In contrast, while MAC address filtering can control which devices are allowed access to the network, it does not inherently prevent those devices from seeing each other once they are connected. Client bridge mode is used to connect different network segments but doesn't provide isolation among clients. Client mode, similar to client bridge mode, also allows connections but doesn't address the visibility issues between users. Thus, client isolation mode is specifically designed to enhance user privacy and security by preventing inter-client communication on the network.
