Moglor USB Wifi Dongle impossible to use

Hardware Wireless
1

I have this USB mini adapter of brand “Moglor”.

lsusb says this:

Bus 001 Device 008: ID 0bda:0811 Realtek Semiconductor Corp. Realtek 8812AU/8821AU 802.11ac WLAN Adapter [USB Wireless Dual-Band Adapter 2.4/5Ghz]

I’ve followed the driver instructions here https://hub.libre.computer/t/realtek-wifi-drivers/57:

For RTL8812AU use rtl8821au .

sudo apt install -y build-essential bc flex bison
git clone https://github.com/aircrack-ng/rtl8812au.git
cd rtl8812au
ARCH=arm64 make -j`nproc`
sudo ARCH=arm64 make install
sudo modprobe 88XXau

wlan0 appears, but that is all. Unable to scan or connect.

Please, help me.
Thanks in advance.
