Summary

Throughout this chapter you’ve learned various troubleshooting techniques associated with some common problems to wireless networks. As stated at the beginning of this chapter, there will always be a troubleshooting component for wireless networks. That being said, being proficient at solving complex issues will set you apart from your peers if you’re able to carefully dissect and solve problems.

When approaching a new issue, remember to be systematic: start at Layer 1 of the OSI model by checking physical connections. Ask yourself if power is being supplied and if antennae, cables, connectors, and adapters are connected and oriented properly. From there move through the model to determine if you have Layer 2 connectivity or if other problems are occurring with the protocols at this layer. You then should check Layer 3 connectivity and stability. Collect as much information and diagnostic material as possible, target common problems, find the consistencies in the problem, and take advantage of professional troubleshooting tools. Remember: debugs, protocol and spectrum analyzers, support forums, and surveying tools are your friends,....
