The devices connect at 5Ghz, which we have MBR set to 12. If we were to change it to 24, it would reduce the cell size and I would need to re-survey and potentially re-configure the signal settings on all the AP's. The current Tx Power is manually managed based on in house surveys, so they are not too skewed. The funny thing is that in one location, we have AppleTv's connecting to an adjacent rooms AP, which has it's Tx power set lower than the AP in the room where the AppleTv resides. So it seems that the devices are illogically choosing their AP, which is why i'm looking for a definite way to lock them down. Thanks.
