Alpha USB in monitor mode

These instructions assume that you are using Ubuntu Linux. You MUST turn off the wifi adapter in the graphical user interface in the top right of the screen in Ubuntu.

Usually you would do this as the first thing in the labs, but I have seen cases where there aere permission denied errors unless this is done after this command sudo iwconfig wlan0 mode monitor

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

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 must 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.
