Time for action – creating a monitor mode interface

Let's now set our wireless adapter into monitor mode.

Follow these instructions to get started:

Boot Kali with your adapter connected. Once you are within the console, enter iwconfig to confirm that your card has been detected and the driver has been loaded properly.
Use the ifconfig wlan1 up command to bring the card up (where wlan1 is your adapter). Verify whether the card is up by running ifconfig wlan1. You should see the word UP in the second line of the output as shown in the following screenshot:
To put our card into monitor mode, we will use the airmon-ng utility that is available by default on Kali. First run airmon-ng command to verify whether it detects the available cards. You should see the wlan0 interface listed in the output:
Now enter airmon-ng start wlan1 command to create a monitor mode interface corresponding to the wlan0 device. This new monitor mode interface will be named mon0. (You can verify if it has been created by...
