What is the effect of station isolation when a VLAN is not configured?

Station isolation is a security feature that restricts communication between wireless clients on the same access point (AP) radio. When VLAN is not configured, station isolation becomes significant in controlling how clients can interact with one another. It ensures that while clients connected to the same AP cannot directly communicate or share data, they can still connect to the network and access shared resources or the internet.

This property enhances security by preventing unauthorized data exchange and potential attacks among clients who are sharing the same wireless connection. Clients connected to different APs may still communicate depending on the network configurations beyond the access point level; hence, enclosure of direct client communication only applies when they are on the same AP radio.

Thus, the effect described in the context of station isolation accurately highlights that it specifically restricts traffic only between clients on the same AP radio, leading to increased security and reduced risk of lateral movement within the network.
