Wi-Fi is the most prevalent wireless network deployed worldwide. This course teaches you how to capture Wi-Fi traffic, analyze Wi-Fi capture in Wireshark, and troubleshooting complex problems in Wireshark, including 802.1X authentication and QoS.

Are you responsible for designing, implementing or managing a Wi-Fi network? Or simply want to understand how Wi-Fi works? In this course, Using Wireshark to Analyze and Troubleshoot Wi-Fi Networks, you'll learn how to capture, analyze, and troubleshoot Wi-Fi networks in Wireshark. First, you'll learn how to capture Wi-Fi traffic over-the-air, including how to select the best hardware, and how to configure that hardware in your preferred OS environment. Next, you'll explore how Wi-Fi is the only protocol where Wireshark provides physical layer information utilizing the de facto Radiotap standard. Additionally, you'll discover the 802.11 MAC header and elements, learning how to filter on key fields, such as the retry flag to find re-transmitted frames, and the protected flag to determine if your network traffic conforms to your security policies. Lastly, you'll cover the 802.11e Quality of Service (QoS) setting and how to ensure your traffic is being given the appropriate priority over the Wi-Fi network. By the end of this course, you'll have the necessary skills and knowledge to navigate Wireshark to analyze and troubleshoot your Wi-Fi networks with confidence.
