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!
