Hi, first sorry for my English but it is not my native language.
So I'm on a all fresh installation of kali 2020.4 on pc (not vm)

using alpha AWSU036ACH used Realtek 8812au chipset.

when trying to use airplay-ng deauth, seem to work well cause sent paquet to device Mac adresse attacked but internet connection is still operational and no handshake discovered by airodump-ng.

aireplay -9 (test fonction monitor and injection said all is ok injection and monitor mode but in reality, it is not, seem to work well but it doesn't.

try a lot of different drivers, sources drivers, installing deinstalling driver etc, command process like down and down wlan lot of time , ifconfig mode monitor etc etc. Impossible to fix it. And this on lot of different pc, laptop, vm etc

reaserch on www find a lot of user said have the same issue with Realtek driver wifi adaptator rtl8812au, 8814au, 88XXau.

have you successfully to fix it?
some repository or driver compatible?
Many thanks.
