Methods, apparatuses and systems facilitating the management of wireless computer network environments and the detection of rogue and other devices that may affect the performance and/or security of the wireless computer network. The present invention enables accurate and cost effective WLAN airspace mapping. In one embodiment, the present invention allows any conforming access point the ability to routinely scan its airspace, collect data on all operating frequencies and report this information back to a management platform. In one embodiment, the management and reporting functionality described herein uses a standards-based vehicle, such as Simple Network Management Protocol (SNMP). In one embodiment, the present invention allows for detection of all wireless traffic within or affecting an enterprise's computer network environment, picking up all active access points (Ad Hoc or Infrastructure) and all wireless clients data regardless of SSID, channel, or security settings. The management platform, according to an embodiment of the present invention, analyzes information received from the access points under management to detect and report the state of the computer network environment. In one embodiment, the present invention facilitates isolation of rogue wireless devices affecting the computer network environment and effective decision-making as to management of the detected device. The present invention also allows network administrators to optimize the configuration of the wireless network environment for performance and security.
