Constant random wifi drops with IAP-205s

I am supporting an office with 6 IAP-205s and we have a random set of users that are disconncted from the wifi several times a day.  It happened to me and the Windows event logs show "Failure Reason:Security failed."  The users are on Windows laptops, iPhones, iPads mostly, but we haven't limited it to just those users.  On the other hand a user that used to have constant issues had no issues while others report this problem.

 

We are using a Windows Radius server and WPA2-Enterprise on in the instants.

 

Any tips on how to get more insight on what that means and how to fix it?

 

Thanks!

We are currently running 4.1.1.0, specifically: 6.4.2.0-4.1.1.0_45444.

 

Should we upgrade?

 

Thanks!
