Hi kcdtv,
I see, you are replying to everyone with passion. Thank you for that help.
Alfa awus036ach was also not getting installed on Kali (dual boot). Your last suggestion about apt dist-upgrade has possibly worked.
I repeated the dkms package installation after uninstall.
Suggestion on Kali site is this which i used:
apt update
apt install realtek-rtl88xxau-dkms
Thank you
