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

["Jean-François Ingelaere" <masterprenium@gmail.com>]

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,
