Hello, I was setting up my adapter to run airodump-ng, but then this happened. This is the first time I am experiencing this issue.

root@kali:~# ifconfig wlan0 down

root@kali:~# iwconfig wlan0 mode monitor

Error for wireless request “Set Mode” (8B06) :

SET failed on device wlan0 ; Operation not permitted.

I couldn’t find any solutions online

I would greatly appreciate help on this. I also ran through this problem too:

root@kali:~# ifconfig wlan0 up

SIOCSIFFLAGS: Operation not possible due to RF-kill

Hi!
Can you tell me the exact model of your adapter?(brand and model)
Is this the first time that you try it?

Thanks!
Diego

My adapter is Alfa AWUS036ACH. I have ran this multiple times with no issues at all. For more context… i hadn’t tried packet sniffing in a while because I was learning the MITM attack. During learning the attack I did connect the adapter for the first time to a wireless network (which was mine). Maybe connecting it for the first time messed something up? Just trying to give as much info as possible, maybe it’s useful.

Hi!
Can you try to use:

ifconfig wlan0 down
airmon-ng check kill
iwconfig wlan0 mode monitor
ifconfig wlan0 up

Let me know how it goes!

Hello,

I am getting the same response. I also tried deleting the drivers and installing them back, still the same bug. I also went back to an older snapshot and deleted the usb from VB and put it back on. None of those worked.

Hi!
Are you using the latest custom kali image provided by Zaid?

Let me know.
Diego

[samuel cauneac]

Yes, I got it about a month ago.

Hi!
Can you share a screenshot when using the command I suggested?

Thanks!
Diego

root@kali:~# ifconfig wlan0 down

root@kali:~# airmon-ng check kill

Killing these processes:

PID Name

1508 wpa_supplicant

root@kali:~# iwconfig wlan0 mode monitor

Error for wireless request “Set Mode” (8B06) :

SET failed on device wlan0 ; Operation not permitted.

root@kali:~# ifconfig wlan0 up

SIOCSIFFLAGS: Operation not possible due to RF-kill

root@kali:~#

I ended up installing a fresh install of kali instead of the custom one from Zaid, everything works good.

Hi!
Cool you got it, the only disadvantage is that some of the attacks like https downgrading, installing mana and maybe installing veil will not be possible in official kali release, but ry them out first.

Why wont they work? Is it because of legal purposes?

[Diego Pérez]

Hi!
No, for different reasons. Https downgrade will need custom hstshijack caplet and bettercap 2.23 but even if they are installed in custom kali many students still having issues. Mana is not supported any more by official kali, veil has many incompatibility issues.

Greetings!

Hi , I’m 70ty years old, very little computer experience, and am just starting the course for beginners, I had the same problem, but took me 5 mins to solve it. if you are using a wireless built in connection, (not hard wired) Simply disconnect your wireless connection, then follow the instructions in the video lesson. Once done. Turn it back on. run iwconfig you will see it is in monitor mode. Hope that helps?

Hi Alfie!
Thanks for the tip!

Greetings!
