When a suitable AP is detected (with the same SSID), its RSSI level is compared with the RSSI level of the currently connected AP. This comparison is done at any RSSI level of the currently connected AP and regardless of the defined RSSI level threshold explained above.
Another reason to roam is if the currently connected AP disappears. In this situation, if a suitable AP was detected beforehand, the station connects to it; otherwise, it invokes a scan to detect it. If no AP is detected, the station disconnects and starts a periodic connect scan.
