Kali 2.0 Airodump-Ng wlan0mon Doesn't Work

Hi i have problem in Kali 2.0 with airodump-ng im using an external usb wifi adapter:

root@kali:~# airmon-ng
PHY Interface Driver Chipset

phy0 wlan0 rt2500usb D-Link Corp. AirPlus G DWL-G122(rev.B1) Ralink RT2571

root@kali:~# airmon-ng start wlan0
Found 5 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 kill (some of) them!

PID Name
772 NetworkManager
905 wpasupplicant
943 dhclient
1106 avahi-daemon
1111 avahi-daemon

PHY Interface Driver Chipset

phy0 wlan0 rt2500usb D-Link Corp. AirPlus G DWL-G122(rev.B1) Ralink RT2571
(mac80211 monitor mode vif enabled for phy0wlan0 on phy0wlan0mon)
(mac80211 station mode vif disabled for phy0wlan0)

root@kali:~# airodump-ng wlan0mon
ioctl(SIOCSIWMODE) failed: Device or resource busy

ARP linktype is set to 1 (Ethernet) - expected ARPHRDIEEE80211,
ARPHRDIEEE80211FULL or ARPHRDIEEE80211PRISM instead. Make
sure RFMON is enabled: run 'airmon-ng start wlan0mon <#>'
Sysfs injection support was not found either.

The error message tells you, run "airmon-ng start wlan0mon".

I had the same problem with mine, but I managed to fix it like this

airmon-ng start wlan0

airmon-ng check kill

airodump-ng wlan0mon

if that doesn't work try to
airmon-ng stop wlan0 after airmon-ng check kill

then just type as you would normaly do
airmon-ng star wlan0

airodump-ng wlan0mon

I hope this will help :)

Random Info:"The avahi-daemon discovers network resources, allocates IP addresses without the DHCP server, makes the computer accessible by its local machine name by acting as a DNS server and facilitates sharing of files and printers. The Avahi daemon is a default daemon in Linux and uses system resources and reduces the network performance."

This card will packet inject so it's something on that end. Maybe like Comment #1 and #2 suggest.

use
ifconfig wlan0 down
iwconfig wlan0 mode monitor
ifconfig wlan0 up

PID Name
772 NetworkManager
905 wpasupplicant
943 dhclient
1106 avahi-daemon
1111 avahi-daemon

kill some of These processes, especially avahi-daemon.

Do it like this:

airmon-ng start wlan0mon
see if it lists processes
kill one of them
airmon-ng start wlan0mon

repeat until no interrupting processes are listed.

For me, both the NetworkManager and the avahi-daemon made Monitor mode impossible.

first put it in monitor mode and then try again, should work

I've had that problem since kali 1.0.9 use:'iw phy phy0 interface add mon0 type monitor' to create monitor mode on 'mon0'.

Thnx , but after that i cant find any station associated to wifi target
