I apologize for the redundant question. It seems like "clients disconnecting" is a common topic. But I am starting a new one, because it seems that every situation is different.
I have a C5210 and a bunch of 3825i AP's all over my hospital. Just before Christmas I upgraded to the latest firmware, 10.21.01.0065. Since then I am getting complaints from users (across the board) that they are frequently getting dropped from WiFi. After it happens they are easily able to reconnect and all is well. But it's driving them mad as they will be in mid-sentence documenting in their various applications and then it sort of freezes up and KAPOW! Connection lost!
There is nothing newer to upgrade to. And I suppose I could downgrade to see if the problems goes away. But I would rather seek out the source of the problem and fix it. Especially if it's just something wacky in my configuration.
I plan on putting in a call and opening a ticket on Monday morning with support. But in the meantime - does anyone have any ideas for me? I use Netsight and Purview, and I have all of these logs and diagnostic data at my disposal, but I am not really sure where to start. I suppose the first question is - does anyone else have this issue with this firmware?

I don't think this would be the cause of your problem. Just looks like the driver is trying to recover from a lack of connectivity.

Hello Ron, I found it rolling through the Application log (Event Viewer > Windows Logs > Application) filtering on types: Error, Critical, and Warning.

Could you share in which section of the event viewer I'd find such information - I'm too lazy to search for it 

according to https://supportforums.cisco.com/document/141136/80211-association-status-80211-deauth-reason-codes
deauth reason=2 is "Previous authentication no longer valid"
Could you tell us more about your authentication setup? Are you utilizing Extreme access control?

Nope. Nothing that fancy - yet. So the only authentication I can think of would be the PSK-TKIP passphrase. And why would that no longer be valid?
Perhaps there is some sort of session expiration value that I need to address?
