This paper shows the vulnerabilities of the 802. Hi Wireless Networks. We propose two lab scenarios capturing the management and control frames for analysis in Wireshark followed by a comparison of the advantages and disadvantages of each scenario in order to implement the best option in a real world setting. The first test scenario involves an access point with the capacity to have a Sniffer installed to monitor its network traffic. The second scenario is implemented with a regular AP, which uses an external adapter to capture the Management and Control frames. Both lab scenarios will provide us with valuable information through the Sniffers to detect weaknesses throughout the wireless network according to the 802.11i standard.
