Aireplay-ng help

[abrocky]

hi

just trying to get to grips with the aircrack suite, and have fun into a small problem. When trying to fake authorisation I get:

 aireplay-ng -1 0 -a xx:xx:xx:xx:xx -h 00:11:22:33:44:55 ath0

Authorisation failed (code 256)

i have correctly set my mac to 001122334455 (iwconfig).
i can get ARK replies on the -3 code if have a computer on the network, but also want to be able to fake auth as well.

I am using a NetGear WG511T pcmcia

* Driver : Madwifi-ng
* Chipset : Atheros
* Notes: Works with Backtrack, (out of the box).

Supports all current Aireplay-NG attacks (-1,-2,-3,-4,-5)

can any one help? have looked at the aircrack help site, but tried the different command codes given for the ''fussy APs' but they also come up with the same error.

You need to include the ssid of the AP

-e YourSSID

sorry forgot to mention, have tried that as well... have even tried putting the SSID in " " marks... any other ideas?>
