The USB dongle works just fine.

Just a thought, but there is a capitalization error. It should be:

sudo iwconfig wlan1 mode Monitor

not:

sudo iwconfig wlan1 mode monitor

add non-free firmware to repository list ( /etc/apt/sources.list ) Replacing squeeze with whichever version you are using (wheezy, jessy, sid…):

echo "deb http://ftp.us.debian.org/debian/ squeeze main non-free" >> /etc/apt/sources.list
echo "deb http://security.debian.org/ squeeze/updates main non-free" >> /etc/apt/sources.list

echo "deb http://backports.debian.org/debian-backports squeeze-backports main non-free" >> /etc/apt/sources.list

update and install and reboot (make sure dongle is plugged in):

sudo apt-get update
sudo apt-get update && sudo apt-get install firmware-realtek
sudo reboot

Then:

sudo ifconfig wlan1 down
sudo iwconfig wlan1 mode Monitor
sudo ifconfig wlan1 up

@Blamo27 the adapter you mean? I use the WN722N V2, but I’m thinking about just buying a new one which works without the hassle

Yeah me too I’ve the same problem, nothing to do..
=> I bought the ALFA AWUS036ACH

Which version of Kali did you try? I tried on Kali 2017.3 and it didn’t work either.

Hello,
I had the same issue.
I am using TP-Link WN722N.
Was it a hardware or software issue.
If software issue any idea will it be fixed?

@fire-fly Hi, it’s software. If you bought WN722N V1 you should be fine, but I don’t think V2 will be fixed anytime soon. I bought the same device as @Blamo27 and it works fine.

@rlphkrs What is your kernel version ? And your driver ?

I have the same problem with TL-wn722n_v3 what a waste of time and money.

I managed to get a TL-wn722n_v3 into monitor mode using this driver https://github.com/kimocoder/rtl8188eus, forgot to check the version before buying, it just saved my day.
I’m using Kali 2018.4 kernel 4.18.0

I have TP-Link TL-WN725N and i am getting this error «»Error for wireless request «Set Mode» (8B06) : SET failed on device wlan0 ; Invalid argument»».
I’m trying to enable monitor mode…
Does this support monitor mode??

Hi, Can anyone help to set TP-LINK TN-WN722N V3, on Monitor mode. I have tried many ways but unable to make it. Can anyone please help in resolving this.

Hi, Can anyone help to set TP-LINK TN-WN722N V3, on Monitor mode. I have tried many ways but unable to make it. Can anyone please help in resolving this.

Hi, I am a newbie. I’ve been trying to figure out the same problem like yours for months. The only difference for usb-wifi adapter, mine is TL-WN725n V3. I couldn’t get the interface in Monitor mode but weirdly enough I could still get internet connected through it. Luckily this guy saves my day. I tried to remove old driver that I gathered from various version in github. And started to reinstall new driver which recommended by jocahamilton in his post: https://github.com/kimocoder/rtl8188eus . Yes, it finally worked!!! I got the monitor mode. Maybe you can try out, probably it might worked for you as well.

Can any solve this problem
ERROR:: wireless request «Set Mode»(8B06) :
SET failed on device(name of the device); Operation not supported.

same here. i use TP-LINK TL-WN725N on kali linux on virtual box and everytime i set the monitor mode i got this error ERROR:: wireless request «Set Mode»(8B06) :
SET failed on device(name of the device); Invalid argument.

anybody can resolve this?

Guys please help me out i’ve struggled for more than 2 weeks now with this problem

Error for wireless request «Set Mode» (8B06) :
SET failed on device wlan0 ; Operation not permitted.

I have tried anything and now i’m just stuck.

i have got this error too before i managed my kali linux to recognize wifi
connection by plugging in a wireless adapter plus installing the driver.

are you struggling on kali linux on virtual machine?

Yes with the drivers above monitor mode works on ubuntu 4.15.0-96-generic this this way:
ifconfig wlan0 down
iwconfig wlan0 mode monitor
ifconfig wlan0 up

Correct, this same issue I had with the wrong driver installed. Try this one. https://github.com/kimocoder/rtl8188eus

Still no solution for this issue ?

• Installed Kali on my asus laptop:

Same problem please help

Problem solved by for my AWUS036ACH on latest Kali Linux by installing driver RT8812au v5.7.0 branch:
https://github.com/aircrack-ng/rtl8812au/tree/v5.7.0

Follow install instruction:
$ sudo apt-get install dkms
$ sudo ./dkms-install.sh

Then, set monitor mode:
$ sudo iwconfig wlan1 mode monitor

All aircrack-ng suite works perfectly fine.

Hello , i have a problem in the second step in fluxion for to create a «captive portal » this message appears when I select my wifi card :

can someone Help please?

iwconfig wlan0 mode managed
Error for wireless request «Set Mode» (8B06) :
SET failed on device wlan0 ; Operation not permitted.

if You are getting this error it means you are already in manged mode. sometime you set it into monitor mode but if wifi adapter physically eject by little push then it will again back to the managed mode. At the same time if you are trying to make it manage then it gives error because it is already in managed.

Having Kali in Virtual Box on Windows 10. Updating drivers for my Wi-Fi adapter on Windows 10 fixed issue.

I also personally use this adapter TLWN722N and I’ve faced the same issue
Error for wireless request «Set Mode» (8B06) :
SET failed on device wlan0 ; Operation not permitted.

To solve this issue you’ll need to set mode to auto by running the following commands :-
sudo ifconfig wlan0 down
sudo iwconfig wlan0 mode auto
sudo ifconfig wlan0 up
sudo iwconfig

After running these commands restart your machine

NOTE:- Always set to auto mode before shutting down your computer or else you’ll face the same issue

any blacklisted module/driver in /etc/modprobe.d/ ?

Thanks NabeelJiwani but the problem is that i don’t know what to do next.

My problem is, when I shut down my virtual machine and make the iwconfig wlan0 auto before I shut down my machine the error in the next session appears again. And when I see this error I just want to break everting near me.

Just sharing my finding:

I was getting the same error (Set Mode (8B06)) when running the «iwconfig wlan1 mode monitor» command.
However, I was able to fix/workaround it by bringing the adapter interface up then down again then setting to monitor mode. Not sure what is causing the issue but this seems to fix it (for me anyway)…

Here are the commands:
ifconfig wlan1 up
ifconfig wlan1 down
iwconfig wlan1 mode monitor

Notes:

• Using AWUS036ACH
• Screenshot attached to illustrate
• Didn’t read all comments

Hoping this might save someone time.

I just used command sudo apt-get install dkms
and its working fine now

I’m also using TL-WN722N ((V2/V3) and I also intermittently experience the same problem. This is how I solve it… with your adapter still plugged-in:
rmmod r8188eu.ko
modprobe 8188eu
Disconnect your adapter and reconnect. Now you should be able to put it in monitor mode. If it still fails, put it to auto mode first, down it, and now put it to monitor mode.

Thank you! You just help me tremendously. I signed up with GitHub because of you.

Same issue with RasPi on 3+ — Recompiled with «apt install raspberrypi-kernel-headers» but still have to put it down and up..? Why is it doing that remain a mystery to me :/

finally someone who knows a solution,this has been wreaking havoc for me,THIS IS THE FIRST STEP IN HACKING and it wouldn’t even work,thank you

Sudo iwconfig wlan0 mode monitor
Sudo iwconfig

I can’t believe this thread is still alive, but if you are still encountering this problem this may work for you.

1. take out your adapter
2. sudo rmmod r8188eu.ko
3. put your adapter back in
4. sudo modprobe 8188eu
5. sudo airmon-ng start wlan0

• note* the above command may not work, use iwconfig to check your adapter’s name.*
  6.iwconfig
  you should now be in monitor mode, congrats
  if somehow your are still in auto or managed mode:

1. put your adapter back in
2. ifconfig wlan0 up
3. ifconfig wlan0 down
4. now redo everything mentioned in the beginning
5. this worked for me, but everything is case-sensitive.

Good I’m using a tp link wn823n having the right drivers I get when trying to put the monitor mode with the command airmon-ng start wlan0 and then iwconfig I get manager mode instead of monitor mode and I’ve been trying the commands of the thread and I get the same error and I do not know what to do, if someone can help me. This image is an example but with all commands I get the same error

Hi ArturovI9,

Insert your network adapter first:

1. ifconfig wlan0 up

2. ifconfig wlan0 down

«Take out the network adapter»:

1. sudo rmmod r8188eu.ko

«Insert your network adapter»:

1. sudo modprobe 8188eu

2. iwconfig wlan0 mode monitor

Now, your network adapter should be in monitor mode, again lots of adapters no longer work with kali Linux, also make sure you have the proper drivers installed, and that your adapter is capable of monitor mode.

-Happy Hacking, josh
