Glenn, Cisco Prime Infrastructure (PI) product can assist with a lot of this diagnosis since it collects trend data including information specific to the client such as AP associations, roaming, RSSI, etc. It is a indispensable tool for getting to the bottom of reported client issues. If you don't have it, I'd look at getting it. Your life will be far better.
That said, a few comments: * SSIDs - have you confirmed that they are all setup identically? Lots of knobs can be turned for each SSID that can impact the client * Do you have client band steering or load balancing enabled? In general, while clients have gotten better about honoring the trickery, many still don't. In most cases, clients (especially Apple's) do a great job now in picking the best SSID, so the need for controller tricks is diminished. In other words, disable these if you have them enabled and see if client happiness improves. * Code - Get off of 8.0 (or at least get to 8.0.140.0). Preferably, get to 8.2MR5 where you will benefit from a lot of improvements, not only in client-AP compatibility, but additional features that will make your life a lot easier.

Scenario 2 Physical area: In-doors in Dorms/reshall Infrastructure : Cisco 702W(80%) AND 3702I(20%) with WISM 8.0.133 Customer report: I get slow internet Observation: Customer device not connected to the strongest/closest AP * They might have been until an event happened (rogue AP or channel change) , but they don't go back Client devices - Apple/Samsung/ laptops/tablets/smartphones Troubleshooting - it is not intuitive to find root cause via status codes Additional notes: I am using RF profiles controller power and data rates in an attempt to force them to connect to the strongest and closest AP Recommendations -?
