Look at the AP's power tab on the sessions page. Do you see any SMs at
MIMO-A and/or less than 8X/6X modulation? That's the downlink rate to
the SMs. 4X is going to eat up some air time. 2X and 1X is obviously
even worse. MIMO-A is even more ungood.
I know Aaron talked about adding support to penalize low mod SMs so they
will have less effect on air time utilization. I hope that's coming in
14.3. Or maybe he said for 15.0. I don't remember.

I have a couple 450 APs showing relatively low traffic (20mbps) but
100% downlink frame utilization on a 20mhz channel. I�ve seen this AP
do twice as much traffic with less frame utilization in the past, so
what would be causing this?
