Hello @Anton_P 
To get a fast answer, please post also your system information, especially the chipid of the chipset is important, not the model name.
After searching I found this device:
https://linux-hardware.org/index.php?id=usb:2357-0109
It is the RTL8192EU chipset.
Then search the AUR and you’ll find this here: https://aur.archlinux.org/packages/8192eu-dkms/
It must be installed on the local installation (not the live session) and linux headers are needed. It necessary to have a internet connection first via wired cable or usb tethering via phone.
The run after installation:
pamac update
(check which linux you are running: uname -r)
pamac install linux510-headers
pamac build 8192eu-dkms-git
After reboot the driver should be available.
