There are many threads on the topic, however because you so eligantly posted the thread, I shall give you a somewhat eligent answer.
First of all you need to obtain the PRGA (xor file) that will allow you to send an association request to the AP. However the only method I know of doing this is to de-auth a host while dumping the traffic of the network. You can use the xor from a chop chop or frag attack but they must be over 144 bytes I believe.
So in short, you probably cant do it. Get a client hooked up and go for it.
