Hi,


Ihave been reading through a lot of posts on this topic to try andfind a solution to my problem but I can't seem to find a matching setof circumstances to mine so I thought I would ask. I am running Kali2018.3 on Virtual Box and I have a TP-Link WN722N_V1 wireless networkadapter. I previously had the TP-Link WN722N_V2 but after furtherinvestigation, it seemed like the consensus was that V1 was theoption that would work because it supports packet injection.


Thefollowing are my system specs:


uname-a:


Linuxkali 4.18.0-kali1-amd64 #1 SMP Debian 4.18.6-1kali1 (2018-09-10)x86_64 GNU/Linux



Ihave installed the recommended drivers with the followingcommands:






apt-getupgrade
apt-getdist-upgrade

aptgetinstall linux-headers-`uname-r`

gitclone https://github.com/lwfinger/rtl8188eu.git
cdrtl8188eu
make
makeinstall
modprobe8188eu





WhenI boot up my Kali VM with the TP-WN722N_V1 wirelessadapter plugged in, the green activity LED flashes in a randomfashion as opposed to when it was not working and it flashed at afixed interval. So the drivers seem to have installed successfully.This is an improvement on the situation previously usingthe TP-WN722N_V2 asit was not possible to connect to the internet.

Thenchecking my interfaces:


ifconfig (loentry omitted):

Thenafter entering ifconfigeth0 down (loentry omitted):

Itis receiving and transmitting packets and loading web pages issuccessful. So when I enter the followingcommands:



ifconfigwlan0down
iwconfigwlan0mode monitor


Iget the following error:


Errorfor wireless request "Set Mode" (8B06) :
SETfailed on device wlan0 ; Operation not permitted.



Itseems like I either get the above error or the following when I tryto reset with servicenetwork-manager restart.


Errorfor wireless request "Set Mode" (8B06) :
SETfailed on device wlan0 ; Invalid argument.


Ifanyone has any advice on how to proceed I would be very appreciative.

V1 works out of the box and there are no driver to install.
V2 is another story and I would recommend returning it and buying something else.

About monitor mode, the iwconfig command is deprecated, you have to use iw instead. You can always use airmon-ng to handle it instead. Make sure to kill any network manager prior to putting the card in monitor mode or you'll end up with tons of issues.
