Detecting intruder in Wi-Fi network is found to be the fundamental focus of this paper. The proposed work manually selects file from the location database from which it obtains the Received Signal Strength Indicator (RSSI) value. Distance is estimated by using the obtained RSSI value. By setting RSSI threshold and by using fingerprinting technique (unique MAC address) malicious intruder is detected in the wireless network.
