Summary

This module covered the basics of troubleshooting. After a discussion and hands-on lab activity documenting the troubleshooting process, the student should be familiar with the systematic approach to troubleshooting. This approach minimizes confusion and cuts down on time otherwise wasted with trial-and-error troubleshooting.

Next, a variety of tools were introduced that are used to troubleshoot a WLAN. Students learned about items such as cable testers, which are designed to verify connectivity of all LAN cable types. They also learned about spectrum analyzers, another common tool used by network professionals. The spectrum analyzer is the best tool to determine if there is activity on the frequency.

Finally, the WLSE was introduced. This software allows for effective enterprise WLAN management. The WLSE uses a Web-based GUI for a large number of APs and bridges for configuration changes, security, accounting, faults, and performance monitoring.
