First of all : PLEASE don't use white colors, there are some people using the old board style, it's very hard to read (have to highlight it)
It isn't relevant how many data you can collect, you don't need thousands packets for getting a handshake.
But as you say you've collected some data, i suppose you have a second machine (the client mac) which is generating the data with the AP?
That is the most important thing: no client -> no data -> no handshake.
Sometimes you have to wait a bit longer and/or deauth the client a few times before getting a handshake. You did that?
is a correct command , as i said , try it a few times and wait 1-3 minutes.aireplay-ng -0 1 –a <MAC AP> -c <MAC CLIENT> wifi0
I have the same Intel® PRO/Wireless 3945ABG card, my one also shows power 0, but everything is working fine.
Aircrack is included in BT3 , so what do you mean with using a USB device?and still don't know if i need to or it's possible to install aircrack-ng as soon as i use an USB device !?
becouse i get some messages with many errors
What are these errors?
