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

The AP used is a Cisco C9120AXI-E.
Best regards,
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.
