Newly created monitor mode interface wlan0mon is *NOT* in monitor mode

[vicneanschi]

Device TL-WN722N ver2.1
I was able to install this driver on 4.9.0-kali3-amd64 #1 SMP Debian 4.9.18-1kali1 (2017-04-04) GNU/Linux

When I'm trying to switch to monitor mode

# airmon-ng start wlan0

Found 4 processes that could cause trouble.
If airodump-ng, aireplay-ng or airtun-ng stops working after
a short period of time, you may want to run 'airmon-ng check kill'

WARNING: unable to start monitor mode, please run "airmon-ng check kill"

Does the chipset support monitor mode at all?

I get the same error-message with the Alfa Network AWUS036ACH Realtek RTL8812AU chipset

[Re4son]

To put it into monitor mode, use:
iwconfig wlan0 mode monitor

To disable monitor mode, type:
iwconfig wlan0 mode managed

That'll do the trick.

running well in ubuntu 14.04 but not supported monitoring mode. You can't use aircrack-ng.. I'm still trying to get solution about this problem, any have idea?

[DJT77]

ifconfig wlan0 down
iwconfig wlan0 mode monitor
ifconfig wlan0 up

running airmon-ng start wlan0 should confirm that the interface is already setup for monitor mode.
airodump-ng wlan0 to monitor

Hope this helps!

I'm also using the Alfa AWUS036ACH with Kali Linux in VMware and having problems
I've done

ifconfig wlan0 down
iwconfig wlan0 mode monitor
ifconfig wlan0 up

and this looks OK

However when I enter

airmon-ng start wlan0

I get the following
PHY Interface Driver Chipset

phy0 wlan0 rtl88xxau Realtek Semiconductor Corp. RTL8812AU 802.11a/b/g/n/ac WLAN Adapter

and then hangs - CTRL-Z gets me back to the command prompt

Before this I tried

root@kali:~# rfkill unblock wifi; rfkill unblock all

root@kali:~# airmon-ng

(nothing showing)
run airmon-ng check kill again then
airmon-ng start wlan0

again it hangs and have to use CTRL-Z to escape.

any further ideas please - this is driving me nuts and I have an MSc assignment to write

I'm using ALFA AWUS1900 Adapter and I'm changing it into
monitor mode using iwconfig and it's working in monitor mode in wlan0 interface..
.
.
When I'm trying in
airmon-ng start wlan0

its showing like this

What to do please help

I want it into mon0 or wlan0mon

Because in wash --interface it's not working with wlan0

Please help 😔😕😕😕😕

You use a wrong version. I recommend to use Parrot OS or Kali or BlackArch. All this version are tested and worked fine.

Of course you need compatible Card.

[sampathsahukara]

Yes thanks alot

I don’t know that this specific adapter can be switched into monitor, however if you wanted to switch there are two ways:

First way:

“ifconfig wlan0 down”
“iwconfig wlan0 mode monitor”
“ifconfig wlan0 up”

second way:

“airmon-ng start wlan0”

and to check both type “iwconfig wlan0”
If you look under “Mode” it should say “Monitor”

If you still have trouble try:

“airmon-ng check kill”

This will take out the processes that look like they’re preventing you from switching. After doing that try the above again.

If not, it’s possible that the adapter isn’t able to switch. However if you search around on Github sometimes people build drivers that allow them to switch.

If you’re searching for an adapter that works with kali I recommend rtl8812au as I know that it does have the ability to switch and the drivers can easily be found on Github. The hardware itself is only about $20-$30.
