AP7532 Wing 5.9.8.0 does not meet throughput requirement

[Arthurooo]

Hello,

I am currently running an AP7532 with wing software 5.9.8.0 and I am able to see that we don't meet the throughput requirement for 802.11 ac.

On my configuration, I am running the following settings on radio 2:

- Data rates custom basic- mcs-1s mcs-2s mcs-3s 

- Data rates mcs qam only

- Channel 44ww

By doing iperf3 testing, we are able to see that download/upload over TCP and UDP don't go higher than 220~240 Mbps, whereas the wireless client statistics show that phy rates is 1.3 Gbps. 

The configuration is the following:
