HI Eric
You may not be able to use this in a business I haven't looked lately at the unleashed however you can try this
if it is available
Radio Resource Management:Enable 802.11k Neighbor-list Report (enable this)
and set this to this
Directed MC/BC Threshold: set this to 0
(0-128)Defines
the client count at which an AP will stop converting group addressed data
traffic to unicast
do not allow background scanning and set the 2.4 to channel one only do not use the other 2.4 channels.
I use a ZD1200 and this gives me the availability to set those commands so in a business you may need to go this route
