100 should be enough for smaller networks though. Note that you can send as many deauth packets as you want. This will send 100 deauthorization packets to the router, booting everyone off of it. To do this, type in aireplay-ng -deauth 100 -a wlan0mon

To force people off the network, we are going to send a bunch of deauth packets, essentially DDOSing the network. When they reconnect, we can intercept the handshake. Next, we are going to capture the handshake by forcing people off of the network. In this case, we’re going to try to find the password for router with SSID “mayhem.” Type in airodump-ng -bssid -c -write wlan0mon We can do this by noting the BSSID of the router and the channel that it is communicating on. In order to capture the handshake, we need to isolate the traffic on one router. To capture the traffic, type in airodump-ng wlan0mon Step 3: Capture the traffic and find the handshake We see that wlan0mon is listed under our wifi devices. We can check that we are in monitor mode by typing in ifconfig

Keep in mind that you will kill your wifi connection when you put Kali in monitor mode. If Kali responds with any warnings, type in airmon-ng check kill Open up a terminal and type in airmon-ng start wlan0 We will need a wifi card that supports monitor mode for this tutorial Step 2: Put Kali Linux in monitor mode and view traffic To do this, we can open up a terminal and type iw listĪs you can see, my wifi card has “monitor” listed under “Supported interface modes.” If your card doesn’t support monitor mode, you can buy a wifi adapter from amazon. Step 1: Check if your card supports monitor modeīefore we do anything, you need to make sure that your wifi adapter supports monitor mode.

Crack the password – using a password list, we can use a brute force attack to test each password in the list against the wifi router.

Capturing this handshake is essential to cracking the password.

Capture the handshake – when a computer or phone connects to a router, the devices establish a connection using a handshake.

Put Kali Linux in monitor mode – when we put our device in monitor mode, we can view traffic on that wifi network.

If your wifi card doesn’t support monitor mode, you can’t hack the wifi using this method.

Checking if our wireless card supports monitor mode – the only way we can hack a wifi router like this is by sniffing traffic in monitor mode.

Note: If you do not have Kali Linux, you can buy a pre-made ready to boot USB with Kali Linux on it from our shop or you can buy Kali Linux on Amazon.
