Deauth stage does nothing

[beelzebro]

im noticing that the dauth stage in the WPA phase of the attack is not deauthorizing any users from my network. i was watching two devices and they never lost connection from the internet, never tried to reconnect, nothing. is there a quick fix for this? i have all the necessary software. im using an alfa awus1900, so its not that.

any input would be great.

Are you sure you can deauth at all ? Please try airodump by hand if you haven't:

I had this issue on my awus036ach. I could run other attacks but deauths never seemed to come out of my adapter...

One of the reasons I ask - is that there was a problem for some time with the 88xxau driver that wouldn't send mgmt. frames out (but all the other attacks worked):

If you are using Kali - make sure you have the latest and greatest realtek-rtl88xxau-dkms installed (assuming that's how you get your driver in the first place).
