Your screenshots appear to be from the SM linktest pages. Notice one is
transmitting 4X, thus the 9Mbps uplink. The other is 6X and 14Mbps uplink.
For the downlink, look at the AP's session page to see what it's
transmitting to those SMs and you'll have your answer.

Two different SM's on the same AP with very similar signal qualities,
QoS, etc. However, the linktests are vey different. Has anyone see
this before? Software 3.1.3.
