Hands on lab exercises

Wireshark Setup, Use, and In-Depth Analysis
Wireshark is fundamental to troubleshooting. Labs include:

- Capabilities, configuration, and data display
- Opening, collecting, saving, and modifying capture files.
- Filtering traffic, and using colouring rules as analysis aides.
- Live captures based on a set of desired collection criteria.
- Identify and isolate network problems.
- Conversation analysis.
- Remote packet capture with an AP.

Understanding Frame Components
Familiarity with the frame structure and contents is essential in real -world troubleshooting efforts. Labs include:

- Understanding the MAC header
- Comparing the three major frame types and their subtypes
- Analysing frame formats of individual frame types
- Analysing 802.11n frame components
- Additional information is reported by protocol analysers
- Information not visible in protocol analysers

Frame Exchanges
Understanding frame exchange rules and behaviors is critical to identifying expected and unexpected. It is also necessary to understand what is normal so that aberrations can be properly troubleshot. Labs include:

- Connectivity exchanges and sequences
- Legacy and modern security exchanges
- ERP and HT protection mechanisms
- Power save behaviour
- Acknowledgments, block acknowledgments, and supporting action frames
- Dynamic rate switching
- Band steering

Troubleshooting Common Problems
This lab exposes students to hands-on troubleshooting skills by setting up common problems in WLANs and allowing students to attempt to solve them.

- Trouleshooting connectivity exchanges
- Troubleshooting 802.1X and EAP exchanges
- Troubleshooting roaming

Spectrum Analyzer Setup, Use, and In-Depth Analysis
Specifically, it will explore the plots and charts used to display spectrum data and how to interpret this data to define a transmitter’s impact on the network. The following are covered:

- Installing the analyser and using display and navigation
- The “RF perspective” provided by each plot and chart
- Using built-in features and automated device identification
- Characterizing the behaviours of an interference source
- Assessing the impact of an interference source
- Determining the impact of transmitter proximity on interference.
- Identifying signatures of common transmitters
- Remote spectrum analysis with an AP
