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.
