apt update
apt dist-upgrade

Make sure the device appears in lsusb. If it does, check that it appears in ifconfig; if it doesn't, run modprobe 8812au.
- Restart the adapter in monitor mode:
sudo ip link set wlan0 down
sudo iwconfig wlan0 mode monitor
sudo ip link set wlan0 down
- Test:
sudo aireplay-ng -9 wlan0
