Wi-Fi Roaming: Why Switching APs Is Not the Same as Reconnecting
A device carries the same SSID (Service Set Identifier) as it moves around a building, the service occasionally stutters, and the logs show only one disconnected followed by one connected. That is where many problems get misread. It looks like “disconnect and reconnect,” but what you really need to understand is why the device left the current BSSID (Basic Service Set Identifier), when it decided to switch, and whether security or upper-layer networking had to be rebuilt after the switch.
