Cisco IUWNE 1.0: WLAN Maintenance and Troubleshooting

This course is included in our On-demand training solution.

Overview

Troubleshooting wireless networks presents a unique set of challenges. Unlike wired LAN users, wireless clients are mobile and their relative position within a building is often the most likely culprit in connectivity issues. However, positioning isn’t the only factor that can keep clients from connecting to access points. In an ever-changing RF environment, the connection quality from a fixed location may change over time. Proper maintenance of the wireless infrastructure can help prevent many issues, and good troubleshooting practices can make the detection process much more efficient when problems do arise. This course explains the procedure and reasoning behind controller backup and code upgrade. Design and site survey considerations are also covered, along with descriptions of many of the common and useful troubleshooting tools and techniques.
This course maps to the 640-721, Implementing Cisco Unified Wireless Networking Essentials (IUWNE) exam objectives for identifying basic WLAN troubleshooting methods for controllers, access points, and client methodologies; and understanding RF deployment and troubleshooting issues. As well, the course covers the objectives for using the WLC and WCS troubleshooting tools.
