After using the wireless health yesterday to attempt to resolve a latency issue - I would like to suggest that there be further information available in the Wireless Health - Packet Latency tab.
Seeing the average latency per AP is nice, but doesn't provide enough information to do much with. Similarly with the device types, and especially when the AP shows a high average latency, but the device types doesn't come anywhere near that value (where did the missing latency go?).
I would like it if I could choose an AP from the Packet Latency page, and be shown more information about the specific clients that are contributing to the displayed average.
