Re: FW: Wireless speed regression issue with >6.12.12/6.13.x + firmware update for mediatek MT7925

[Mingyen Hsieh (謝明諺)]

Hi,

Thanks for reporting this issue. We will conduct testing again.

And it is already known that the patch added in 6.12.13 does have some
issues, but we have also submitted new patches to fix.

Currently, these patches are in the maintainer’s tree. It should soon
be included in 6.14 and then ported Back to 6.12.x and 6.13.x.

Perhaps you can test the driver from here:
https://github.com/nbd168/wireless and apply this patch:
https://patchwork.kernel.org/project/linux-wireless/patch/20250317011724.3326979-1-mingyen.hsieh@mediatek.com/

Thanks

Best Regards,
Yen.

Hello guys,

I've just tested 6.14.3 kernel which seems to include the patched 
driver. Issue is still present, in Wi-FI 6.

Here are some more testings :

6.14.3 + firmware-202412x speed is NOT correct in download but correct 
in upload (20Mbps/750Mbps)
6.14.3 + firmware-202504x speed is NOT correct in download and in upload 
(<10Mbps/<10Mbps) 98% of time
6.14.3 + firmware-202504x speed is more or less correct in download and 
in NOT correct upload (400Mbps/<10Mbps) 2% of time

With older firmware, speed results are inverted as in 6.12.12 kernel (DL 
/ UP), with newer firmware, upload never work correctly.

Please note the speed is mono-thread/mono-stream (ex : iperf -P 1), 
while running multiple simultaneous connections, the DL speed with newer 
firmware seems quite OK. While I'm not having any issue in <=6.12.12 
with mono stream.
Remarks regarding upload speed doesn't change.

Any idea ?

Best regards,

It's a bit strange, the latest firmware should be 20250305, there
shouldn't be 202504. May I ask where your firmware came from?

And which AP are you using? I will test there combinations as well.

Best Regards,
Yen.

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.

Re: FW: Wireless speed regression issue with >6.12.12/6.13.x + firmware update for mediatek MT7925

[Jean-François Ingelaere]

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
