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:

Any idea for improvements ?

Thank you for your help.

Morning Arthur,

Can you re-run the test without 2.4 enabled.
Also can you ensure the configuration for WLAN/Radio QOS and int rad 2 is configurated as follows.

!
wlan-qos-policy default
qos trust dscp
qos trust wmm
!
radio-qos-policy default
!
interface radio2
channel 44ww
power 20
beacon dtim-period 1
wlan 1 bss 1 primary
wlan 2 bss 2 primary
wlan 3 bss 3 primary
no dynamic-chain-selection
!
Note: also remove custom data rates from the wlan.

If speed is still slow please send output from "show wi cl st rf" and "sh wi ra st rf" for review.
