@CraigBeck ... Putting my faith in you here, aswell as the other experts.
Dived into a rather strange issue today, which I had not too much time onsite to troubleshoot - so while waiting for next opportunity to look at this, maybe some others have had these issues;
-On all 802.1X secured networks, random disconnection issues arise. Clients are disconnected for no particular reason, then reconnects automatically. From the NPS logs we see only reauthentication, which is successfull. Wireless Controller logs show no deauth for that client, only successful reauths.
This is, very very most super unlikely RF problem, as the issues is organization wide, for both dense and sparse deployments - in RF-crowded environments, and RF-uncrowded enviroments - with no neighbouring APs. This also happens to all types of clients (Win7, Win8, OsX, iOS, Androids ++)
The only common is NPS server and wireless controller --- logs OK for both.
Aruba 7210 controller ... which I really is supposed to be on top of --- any ideas 802.1X auth-wise?
btw; one lead might be the Pairwise Master Key ---- which we're looking in to
