I have a deployment of numerous APs in a multi-level structure made of steel/concrete/concrete blocks.  One area in particular, there is some overlap from the AP devices are SUPPOSED to connect to, and an AP from the floor below.     On occasion, the devices will associate with the 'interfering' AP instead of the AP they are supposed to.  I can't lower output on the 'interfering' AP because it needs every ounce of power to cover the area it is designated to cover, I can't adjust the RSSI on the client devices, and I can't remove the SSID from the 'interfering' AP because it is needed in the area it covers.  Is there any way I can just prevent these 7 client devices from associating with that 'interfering' AP?  Like a block list that only applies to one AP?  Will that even work, or will the clients just see the signal, try to associate, and basically end up in the same boat? ...
