As far as i know, when backtrack starts it boots on text mode and the wifi(wlan0) is down in order to be more stealth. Kali linux is the update of backtrack and when I boot it always starts in GUI mode. Is it possible to start it in text mode?Also i noticed that it asks for a wifi connection, so i suppose that the stealth of wifi scanning is not valid anymore?

Thanks @jan, you give me some clues. I added an answer because i wanted to give the full/good tutorial/explanation.So, the GRUB must be edited by pressing tab and adding for example the run level 2. this is done by adding 2Kali runlevel 2 still having the internet and the GUI. This can be easily modified with the following tutorial:http://santhecoder.blogspot.fr/2013/07/boot-kali-linux-in-console-mode-command.html
