what happens when you attempt to communicate with it?

sudo iw link set wlp1s0f0u4 up

if that doesn’t work, check the driver status

sudo dmesg | grep usbcore

you should get information back that shows something similar:

[   10.562887] usbcore: registered new interface driver btusb
[   10.612572] usbcore: registered new interface driver usbhid
[   10.922029] usbcore: registered new device driver r8152-cfgselector
[   11.766981] usbcore: registered new interface driver r8152

you can also try using nmcli or nmtui and check if the device is there and you can configure or change settings.

In nmtui there is an option for Radio and set the status

Still puzzled by this. Would you be able to download a Debian live ISO and try your device on the live environment?

I have a Debian-Testing installation on one of my Computers,
but there too I would need to install the driver from the git repo,

already bought a replacement stick so no need to spend more
effort on this.
Thanks for your assistance though, which I really appreciate
