AX200 upload slower than download

[andrew01]

Hi,

I have AX200 card in my Thinkpad X260 connected with 802.11ax router (Huawei AX3 Quad Core).
I can download from a local NAS server at 110MB/s speed, but upload only at 60MB/s.
Window 10 and drivers are up to date.
What coud be the reason of slower upload speed?
Wired connection is OK, upload/download over 100MB/s.

Best regards
Andrew

Hi Andrew,

How is the NAS server connected to the LAN?

What is the model and brand of the NAS?

Do any other devices connect to the NAS, and if so, what transfer rates are those devices reaching?

Hi Khun_Doug,

thank you for the questions but the problem is solved, a clean Windows installation helped.

Best regards
