TL-WN722N v2 - monitor mode + mfruba kernel problem

[dominikk]

Hi,

I bought TL-WN722N v2. I want to use it in monitore mode.
I heard there is a many problems, but also found a solution.

https://github.com/mfruba/kernel

When I try to compile it, after make I've got a problem like that.

build is a symlink to the Linux kernel source.

Make it using

Code: Select all

sudo ln -s /home/pi/src/linux /lib/modules/$(uname -r)/build

Change directory /home/pi/src/linux to the directory where your Linux source/headers is.

[MrEngman]

That is not the kernel source.

To compile a module for Linux you need to get the Linux source or headers and prepare it for compiling the module before then compiling the module.

There is a script that can do it although I have never used it. Take a look here

The post is old but I'm fairly certain it is still being used as I've seen it mentioned in various posts quite recently.

As far as I'm aware this script installs the kernel source for the current kernel you are using and then configures it for compiling the module you want to compile.

Thanks for helping.

I install sources manualy.... and now even change the distro for Kali and I have still this problem.

I have no idea how to run WN722N v2 on monitor mode

I've never used monitor mode so can't help there. However, you need a working driver first. No idea what is giving the errors now you have the symlinks fixed.

You might find the following some help. I have a script which will automatically determine the driver you need for the Raspbian kernel version and wifi you are using and download and install it.

Download and install the script with commands

Code: Select all

sudo wget http://www.fars-robotics.net/install-wifi -O /usr/bin/install-wifi
sudo chmod +x /usr/bin/install-wifi

The command

Code: Select all

sudo install-wifi -h

will show details on using it.

To install the driver on your current kernel you should just need to run command

Code: Select all

sudo install-wifi

This will select the driver you need and automatically download and install it.

This script handles drivers for 8188eu, 8192eu, 8812au/8821au and mt7610 wifi modules.

[Ronaldlees]

I think the OP meant the driver was the reason he can't run monitor mode. But once he gets an appropriate driver built, running monitor mode is easy, assuming it's legal in his country. AFAIK, it's always legal if used only with the user's own packets. IIRC correctly, something like this is needed:

Code: Select all

sudo apt-get install iw
iw list
    --> should display a list of supported modes:
           IBSS, managed, AP, AP/VLAN, monitor, mesh, etc

If "monitor" mode is in the list, then one or the other ways should work:

• ip link set wlan0 down
  iw dev wlan0 set type monitor
  ip link set wlan0 up
  iwconfig wlan0 down
  iwconfig wlan0 mode monitor
  iwconfig wlan0 up
  ifconfig wlan0 192.168.1.40

Tcpdump can be used to capture WiFi/RF packets:

Code: Select all

tcpdump -I -i wlan0 -w rfpackets.log -XX -n
    ("-I" means "use the RFCOMM mode", -i specifies the monitor interface, -w is for the log file, -XX is for full packet, -n for no resolution)

Then, wireshark can be used to display the logged packets in a nice format. It takes two adapters. One adapter cannot do both a connection and monitor it at the same time. The OP should be sure to unplug the monitor adapter's antenna, and he should take any other precautions needed to be sure he gets only his own packets for inspection. Regulations vary.
