My old usb wifi adapter is working again but new is not doing pretty well

Hello,

OMV LX 3.0.3 updated

KDE plasma updated

Just to report:

About a year ago I’ve reported problems with a wifi usb adapter that had just stopped working after updates:

https://forum3.openmandriva.org/t/networkmanager-last-updates-caused-problems/1075/13

I’ve managed to use a different wifi usb adapter (different chips) and everything was OK but recently this current wifi usb adapter begun to show a weird performance.

The old wifi usb adapter device, however, is working fine again!

Why, if anybody knows, support for this type of devices is like this?

Thanks
