I have been seeing bad packet drops on EAP772 v1. 

I have 3 EAP772, they all have been working well for weeks/months on 1.1.2 until I upgrade one of them to 1.1.4. I see major dropped after ~20 minutes. 

Since i cannot downgrade to 1.1.2, I find the preview 1.2.0 and upgrade that one to 1.2.0.  It is better, but after 5 days it again started to see dropped.(in the event log, there is one "Disconnected" event for that EAP, then "connected" after a few minutes).

Since then, I see more than 50% packet drops if I connect to that EAP. 

Please help either fix the issue or provide a way to downgrade back to 1.1.2.

Thanks
