I ask this because when I enable STBC 1-stream, the driver seems to uses Space division multiplexing (can this be disabled/enabled?), since the rate is over 150Mbps. When is STBC activated ?, ...Does Minstrel/ath9k rate adaptation?mechanism?find first check if Spatial multiplexing is better, if not uses STBC ? Thank you for your time
