Very slow Download speed - Upload speed is OK

[Marek Babinčák]

Hi,

I'm getting very low Download speed values. Upload speed is fine. Wifi router is 4 meters away from me.

Tips from #90 or #94 didn't helped.

Tried on Lubuntu/kernel-6.5.0-25 and Fedora/kernel-6.7.9-200 both running in VMware player 17.5.0 with directly assigned USB wifi NIC.

$ lsusb -vv

Lubuntu VM

Example from Windows VM. This is little bit ridiculous with Download/Upload speed ratio.

Made some improvements with switching from USB2.0 controller to USB3.1 in VMware Player.
