backtrack error code 514

[blade61]

hi guys, been using BT3 and BT4 and it works fine.
the adaptor i have is a alfa awus036h which can do packet injection, i have tried it out on a few WEP networks using the command aireplay-ng -1 0 -a (bssid) -h 00:11:22:33:44:55 (interface)

my problem is that tried to inject packets on another network i have found which is exacty the same as the others i have tried before (WEP). the only difference is the channel.
but when i try the command aireplay-ng -1 0 -a (bssid) -h 00:11:22:33:44:55 (interface) i get the following

sending authentication request (open system) ack
authentication successful
sending association request ack
association denied (code 514)
and it keeps repeating.... what is code 514 and how do i fix it???

as i said, have tried packet injection on other WEP networks with the above command and it works fine

any ideas

thank again blade61

Try slowing down your replay speed.

If I'm reading this correctly ... http://download.aircrack-ng.org/wiki...mentframes.pdf it looks like either the AP is overloaded (maybe because of you?) or the AP is trying to respond to an association request that's out of the expected order.
