    Arrow Monitor mode with TL-WN722N v2 wifi adatper

    Hello,

    I simply cannot enable monitor mode.

    Let me give a brief background on what is going on:

    - VMware virtual machine (USB 2.0)
    - KDE Plasma # Nice look
    HTML Code:
    toor@kali:~$ uname -r
    5.6.0-kali2-amd64
    With the adapter connected:

    HTML Code:
    toor@kali:~$ lsusb
    Bus 002 Device 002: ID 2357:010c TP-Link TL-WN722N v2
    Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
    Bus 001 Device 003: ID 0e0f:0002 VMware, Inc. Virtual USB Hub
    Bus 001 Device 002: ID 0e0f:0003 VMware, Inc. Virtual Mouse
    Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    HTML Code:
    toor@kali:~$ iwconfig
    
    lo        no wireless extensions.
    
    eth0      no wireless extensions.
    
    wlan0     unassociated  ESSID:""  Nickname:"<WIFI@REALTEK>"
              Mode:Auto  Frequency=2.412 GHz  Access Point: Not-Associated  
              Sensitivity:0/0 
              Retry:off   RTS thr:off   Fragment thr:off
              Encryption key:off
              Power Management:off
              Link Quality:0  Signal level:0  Noise level:0
              Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
              Tx excessive retries:0  Invalid misc:0   Missed beacon:0
    Secondly, cloned the TL-WN722N drives from https://github.com/aircrack-ng/rtl8188eus.

    Then, I crossed my fingers as I tried those two methods to enable monitor mode:

    1#

    HTML Code:
    sudo -i
    echo "blacklist r8188eu.ko" > "/etc/modprobe.d/realtek.conf"
    exit
    make
    sudo make install
    sudo modprobe 8188eu
    
    sudo airmon-ng check kill
    sudo ip link set wlan0 down
    sudo iw dev wlan0 set type monitor
    HTML Code:
    # ERROR MESSAGE:
    command failed: No such device (-19)
    2#


    HTML Code:
    sudo ifconfig wlan0 down
    sudo iwconfig wlan0 mode monitor
    sudo iwconfig wlan0 set mode monitor
    sudo iwconfig wlan0 mode monitor
    su iwconfig wlan0 mode monitor
    HTML Code:
    #ERROR MESSAGE
      Error for wireless request "Set Mode" (8B06) :
        SET failed on device wlan0 ; Operation not permitted.
    This is what I tried to do in order to set monitor mode, but I keep failing miserably. Can anybody help? Thx

    What i can get is, you brought your wlan down (ip link set wlan0 down), and then want wlan to be in monitor mode (iw dev wlan0 set type monitor).
    It cannot do that since the device isn't there/down.
