Decided to enable fast roaming on my enterpise grade ap based wifi network at home.

Been working on improving the handoff/roaming performance accross my 3 APs and have really been impressed with fast roaming.   So impressed that 802.11r is staying regardless of the outcome here, the switch will be swapped if needed.

Anyway, my one and only HS210 is dropping connectivity, for no reason.  I'd say randomily polling the switch it's 80/20 with the vast majority being unconnected.  

Yet my HS200 is showing no issues and is rock solid.  (1.0/1.2.5)

No DHCP issues either and there's no proverbial tug-o-war ongoing wth the HS210 in question.  It's always connecting to the same AP and honestly have yet to even see it attempt to connect to any other besides the most logical one. Actually in the wifi's controller platform, it's keeping the lease, and sees the device even when the switch has lost connectivity.  

Before enabling 802.11r I never had any issues with connectivity in the year since I've had these smart switches.  Already reviewed switch's firmware, rebooted the switch, cycled the network and cycled the exact connection via the controller.  Seems the HS210 just isn't compatiable with 802.11r .
