Hola bacunos necesito que me ayuden con este error cuando intento crakaear una red con seguridad WEP ya he crakeado varias como unas 13 veces con bactrack 4 pero esta no se deja jejje no se que tipo de error sea pero nomas no se quiere dejar

este es lo que me manda ..

Sending Authentication Request (Open System)
Attack was unsuccessful. Possible reasons:

* Perhaps MAC address filtering is enabled.
* Check that the BSSID (-a option) 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're too far from the AP. Get closer, or lower
the transmit rate.

de ante mano gracias por su ayuda°!!!!!
