let me just start off by telling you that wikihow and the like are sometimes full of crap so dont rely on them...
i would highly reccomend using wifite 2 as @Bigbiz said.
you can install it with apt
sudo apt-get install wifite
then you may need to install
bully
pyrit
hxcdumptool
hcxpcaptool
macchanger
foe macchanger its
sudo apt-get install macchanger
the rest are "git-clone" and it will instruct you....
or all this could be done as i forgot you said you use kali... woops
oh well ill post this anyway.. have a nice day/night and good luck with it
Also if you are looking to crack passwords on wpa2 i can help with that too
