Intel AX201 speed at 5Ghz transfer SMB only 1mb/s

[EllisXillia]

i use my Thinkpad L13 Yoga with Intel AX201NGW, and i use TP-Link AX5400 at 5Ghz for daily. 
i notice my download speed completely inconsistency aroung 1.4mb/s while download files from google drive

but transfer files from nas over air is even worse at 1mb/s it even use 5ghz mode

when i switch to 2.4ghz wifi it's completely normal and i got maximize speed from wifi card around 52mb/s to 75mb/s on my previous laptop use intel AX210. but in this wifi card and  20mb/s is completely annoying for me

from shouout wiki it say intel can match my wifi6 speed but i tried to match band of intel AX201 capable but none of them are got over 2mb/s at 5ghz wifi

i tried uninstall and reinstall driver, download old driver and doesn't help my problem. is there away to fix this problem ?

Hello EllisXillia,

Thank you for the quick reply.

I can see that you are using the OEM drivers which is also recommended.

You may try the Intel generic driver and check if there will be improvement in the speed.

Download the driver here:
