Alpha USB in monitor mode

These instructions assume that you are using Kali Linux, but there is no reason that it should not also work for Ubuntu. If you are in Ubuntu or Rasbian, I would recommend turning off the wifi adapter in monitor mode.

First we must connect the USB directly to our Kali VM. 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

You should NOT see a wlan0 interface, this is because we have not yet installed the drivers.

Identify which is your wireless interface name. It will probably be wlan0.

Issue an:

lsusb

You should see a line describing the Realtek netork adapter. Now, we need to compile the driver against your kernel headers.

Install the required build tools:

sudo apt install git dkms bc

Clone the Git repo

git clone https://github.com/morrownr/8812au.git

Cd into the directory

cd 8812au

Compile

make

Then install

sudo make install 

Now reboot your Ubuntu/Kali virtual machine.

sudo reboot now

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.

sudo ifconfig wlan0 up                         # Make sure the interface is down 
sudo airmon-ng check kill                      # Kill things that might interfere with the process
sudo iwconfig wlan1 mode monitor               # put it in monitor mode
sudo rfkill unblock all                        # Make sure there are no hardware bocks
sudo iwconfig wlan1 channel 1                  # Set the channel
sudo ifconfig wlan1 up                         # Bring the interface back up

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