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 down # Make sure the interface is down sudo airmon-ng check kill # Kill things that might interfere with the process 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 # Set the channel sudo ifconfig wlan0 up # Bring the interface back up
Now you should be able to capture on your wireless interface in monitor mode.
