Attack was unsuccessful. posisible reasons:

* Perhaps MAc address filtering is enabled.
* Check that the BSSID (-a opition) is correct
* Try to change the number of packets (-o option).
* The driver/card doesn`t support injection.
* This attack sometimes fails against some APs
* The card is not on the same channel as the AP.
* You are to far from the AP. Get close, or lower the transmit rate.
