When two access points (APs) use the same SSID, who controls the wireless roaming behavior?

The correct answer highlights that the wireless clients control the roaming behavior when two access points are using the same SSID. This means that the decision to switch from one access point to another as clients move around is primarily made by the client devices themselves.

Wireless clients, such as smartphones, laptops, or tablets, utilize algorithms that assess the signal strength and quality of the available access points. As a client moves through an area served by multiple APs with the same SSID, it will evaluate which access point offers the best connection based on factors like signal strength and network performance. When the client determines that a different access point would provide a better connection, it initiates the roaming process to switch over.

While other components of the network architecture, such as access points or controllers, play essential roles in providing connectivity and infrastructure, they do not dictate the roaming behavior. Instead, they support the wireless clients by ensuring a seamless experience as they navigate through the coverage area. Therefore, the clients themselves are responsible for managing and controlling their roaming decisions in this scenario.
