This is guide is about how to put your wireless adapter into monitor mode, using Kali Linux and then use Wireshark to inspect the frames (Wireshark comes standard with Kali)
*Not all wireless cards(chipsets)support monitor mode if unsure do a google search. For this I will be using a Alfa Networks card:AWUS036NH.
Step1: check that the NIC is attached type
Step2: Place wireless interface in monitor mode Airmon-ng start <interface name>
Step 3: kill an process that are currently running.
then check that processes have been stopped
Step 4: Put interface in sniffing mode this command will scan over all channels depending on wireless device chipset
Can just sniff on a specific channel with the following command
Once sniffing channels load Wireshark, in in root access you will be presented with the below error message press ok and the select the wlan0mon interface to load the 802.11 frames.
