Guys, I have got a weird problem.
Installed Kali Linux 2020.1 arm image on my Rasberry PI 4 and got my wifi working fine. Both the internal Wifi broadcom onboard driver and my Alfa AWUS036ACH Adapter (USB) with RTL8812AU driver worked flawless using the aircrack-ng tools.
Now here comes the strange thing. After a week or so, I have the following error below
"Ndiswrapper doesn't support monitor mode"
when I put my wifi cards in monitor mode and start to use airdump-ng to capture my wifi traffic.
I have searched the web for possible solutions because I know that aircrack-ng tools do not support Ndiswrapper and it will never be supported. But the strange thing is that i did not install any ndiswrapper drivers in the first place , so I am really puzzled why I have suddenly this error. And the other strange thing is that both my wifi adapters are having the same problem.
Just wondering if somebody ran into a similar problem.
My kali linux version is:
All suggestions are welcome.
