Connect the adapted and establish a baseline

First, we must connect the USB directly to our Linux Virtual Machine. Click VM at the top of your virtual machines. You will click:

VM->Removeable Devices->Realtek 802.11n NIC->connect

Issue a:

sudo ifconfig -a

If you are on Ubuntu, you will get a wlx98oeu8eoh like adapter name If you are on Kali should now see a wlan0 interface.

Install aircrack-ng

sudo apt install aircrack-ng

Put the WiFi adapter in Monitor Mode

Now, when you log back in, you must strictly follow the instructions below to get a reliable monitor mode. Do this one line at a time. Note that if you are on Ubuntu, you will need to substitute wlx93048324, or whatever your adaptor name is, into the part that says wlan0 below.

sudo ifconfig wlan0 down                         # Make sure the interface is down 
sudo iwconfig wlan0 mode monitor               # put it in monitor mode
sudo rfkill unblock all                        # Make sure there are no hardware bocks
sudo iwconfig wlan0 channel 1                  #Make sure you change the channel number to match the AP
sudo ifconfig wlan0 up                         # Bring the interface back up

Now you should be able to capture on your wireless interface in monitor mode.
