I went to a CiscoLive2013-Melbourne breakout session about Troubleshooting WLAN done by Surendra BG- Sr wireless TAC Enginner. It was very informative & show us how to  troubleshoot wireless issues in structured way. Here is the full presentation (BRKEWN-3011)  of that breakout session.

As a reference documents following two documents listed in this presentation. Be familiar with these documents if you are troubleshooting WLANs.

1. Troubleshoot 802.11n Speeds (DOC-112055)
