Maybe becouse you havent said what exaclty your network looks like

If its bridged networkm than you have to separe clients from each other:

1. turn off forwarding on AP
2. user bridge filter
3. Use VLANs

or turn on L3 filter on your bridge, if you still have no success, contact me on PM, i will see what i can do

you can just disable intercommunication in the switch, if it's smart enough. if it's a dumb switch, you will not be able to block sharing, because communications between users will not even reach the router, they will go though switch
