Deauth WPA Question

[Mosh_]

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

maybe:

- macfilter is on?
- your neigbour is too far?

Temp Solution:

I increase the number of packets to send for deauth to 50 and was fine....

aireplay-ng -0 50 -a <BSSID> -c <MAC Client> interface

Yep, 1 is to little.

I am having a smiliar problem and have tried increasing the number to 50 any other reasons for this problem?

How far away is the access point? What security do you have turned on on your router?

Let me know which OS your client is running: Windows XP, Vista, Windows7 ?
