Intel 6E ax211 slow upload speed

[vfrc993]

Good day! 

I have desktop PC with Intel 6E ax211. Windows 11. Driver 22.160.0.3 (also same problems on new 22.180.0.4)

After first turn on everything worked fine, but in few days upload speed goes down (under 1 Mbps). I tried to reinstal drivers but nothing helped. So I decided to reinstall Windows 11. 

Just after reinstall everything worked fine, but again in few days - same problem - slow upload speed (from any WIFI hotspots from different iPhones and one more mobile router). BUT at the same time internet speed was fine on my old laptop.

And again I desided to reinstall Windows 11 with full formatting the entire ssd. Few days everything was fine but in few days - again same problem: slow upload speed from all devices. 

BUT at the same time internet speed on my old laptop is fine as always.

In addition I am adding 4 files

laptop 1, laptop 2 - internet speed from two different mobile operators and 2 different iPhones (on my old laptop)

desktop 1, desktop 2 - internet speed from same different mobile operators and iPhones on my PC

What can be the problem?

vfrc993, Thank you very much for your response and for providing the SSU report.

Accroding to the details shown in the SSU report, the wireless driver version currently installed in your computer is: 22.160.0.3, which is provided by MSI and should be the proper driver for your system since that driver was customized by them to work with your specific platform.

Even though the Intel® wireless drivers are generic and they might or might not work with your specific machine, for testing purposes, please try a clean installation of our latest wireless driver version 22.180.0.4 following the instructions in the links below:
