Hello,
The Cisco Catalyst C9120AXI (not Meraki), is running in Lightweight
mode, connected to the Cisco Virtual Wireless Controller.
I was running tests in 5Ghz, WPA2 + 160Mhz Channel width, not 80 (+all
supported rates enabled, RRM+DCA enabled, 802.11h enabled, BSS enabled).
As tested previously 20Mhz channel width gives better performances than
160Mhz after regression.
Following speed are observed with highest steams as I can (multi thread
iperf/nperf ect). Speed test isn't run in perfect conditions but it
doesn't really mind.
With 6.14.3 + latest firmware 20Mhz channel width (DL/UL) :
130mbps/160mbps (ch36)
With 6.14.3 + latest firmware 40Mhz channel width : 230mbps/330mbps (36,40)
With 6.14.3 + latest firmware 80Mhz channel width : 340mbps/6mbps
(36,40,44,48)
With 6.14.3 + latest firmware 160Mhz channel width : 640mbps/7mbps
(36,40,44,48,52,56,60,64)
As you can see, Upload speed is dropping with 80Mhz channel width. Can
you please try in your setup with 160Mhz ? As a check.
-> With 6.14.3 + latest firmware 160Mhz in 802.11AC (Cisco 2802E):
800mbps/380mbps (52,56,60,64,36,40,44,48)
As a debug/comparison :
With 6.14.3 + 202412 firmware 20Mhz channel width (DL/UL) :
130mbps/170mbps (ch36)
With 6.14.3 + 202412 firmware 40Mhz channel width : 130mbps/280mbps (36,40)
With 6.14.3 + 202412 firmware 80Mhz channel width : 390mbps/580mbps
(36,40,44,48)
With 6.14.3 + 202412 firmware 160Mhz channel width : 630mbps/950mbps
(36,40,44,48,52,56,60,64)
I don't have any other 802.11ax AP at the moment. Remember : no issue
with 802.11ac.
Best regards,
Jeff

Hi,
I had tested with this AP (5G HE80 & WPA2), and my setting is v6.14.3 +
latest firmware. It looked good for me.
Could you give me your AP setting and could you test with another AP?
Best Regards,
Yen.
