Hi everybody

I have a problem with the client deauthentication for a WPA network, i have a ALPHA RTL8197 card and i can normally deauth all clients, but in this test when i try to deauth a client it remains connect to te AP and i can't get the handshake.

i'm using the "aireplay-ng -0 1 -a <BSSID> -c <MAC Client> interface" command.

why happen this ?

Thank you for your time and answers
