Mon0 Wont Start , Kali Linux 2.0

[Help]

Hi I installed Kali Linux 2.0 upon releas date and found various errors/problems.
At first kali linux wouldn't detect my wireless usb antenna so then I had to follow a tutorial elsewhere for kali
to recognize my usb wireless card
then my wireless card started being detected, but when I try to start wlan0
by executing armon-ng start wlan0 I get this :
I am also using ALFA wireless card MODEL:AWS036NH

root@kali:~# airmon-ng start wlan0mon
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
520 NetworkManager
651 dhclient
834 wpa_supplicant
848 avahi-daemon

PHY Interface Driver Chipset

phy0 wlan0mon rt2800usb Ralink Technology, Corp. RT2870/RT3070
(mac80211 monitor mode vif enabled for [phy0]wlan0mon on [phy0]wlan0monmon)
(mac80211 station mode vif disabled for [phy0]wlan0mon)

Im not really interested in anything but this :
(mac80211 monitor mode vif enabled for [phy0]wlan0mon on [phy0]wlan0monmon)
(mac80211 station mode vif disabled for [phy0]wlan0mon)

Im sure this signifies some type of error and please do keep in mind im not that knowledgable,
I do know that if i execute ifconfig I should be seeing mon0 somewhere and that is not the case.
P.S: I have also tried using fern wifi cracker to automatically enable wlan0 into mon0, but upon doing
so it doesnt capture any wifi access points please help someone!

If wlan0mon is enable, wlan0 is already in monitor mode.

[Help]

If i run ifconfig , or airmon-ng it doesn't show anything suggestion that as you can see? Or am I wrong ?

I had a little trouble with my card too. ran airmon-ng check kill before I put it in mon mode and it works fine. The wps supplicant was the only process running and it was stopping my card from working in mon mode.

[Help]

Mine is not detecting any networks though?

Mine is not detecting any networks though?
after you check kill try airmon-ng start wlan0, not airmon-ng start wlan0mon. airmon will put wlan0 into mon mode and rename it to wlan0mon by itself. see if that helps.

i have te some problem whit chip rt 3070 to say bypassing unplug and reconnect the USB socket and restart the monitor seems to work just has some problems when using wash

Your problem is with Network manager. We suggest you read thru this thread and at the bottom we give you a link to the aircrack-ng forums

https://forums.kali.org/showthread.php?26446-Networking-Issue-with-Kali-2-Sana

The quick solution to the mon0 problem is to run

service network-manager stop

You can then work in monitor mode with aircrack-ng tools reaver wash etc.

But the problems are more complicated so again read thru these threads.

NOTE: 90% of wireless issues reported to us are due to people not reading the aircrack-ng documentation. You need to run airmon-ng check kill before putting your card in monitor mode.

Run: airmon-ng check kill before enabling monitor mode.

Hey guys thanks to all your feedback I was able to fix my problem relating the mon0 interface starting up with the following Commands:
aircrack-ng check kill // determined that has to be used first
airmon-ng check kill // also needs to be used first
airmon-ng start wlan0 // from here everything should start working

However I noticed that on every boot up KaliLinux Does not detect my wireless usb card.
Ive had to follow these commands :
sudo su
cd /home/<yourkaliuser>/Downloads
git clone https://github.com/abperiasamy/rtl88...21AU_linux.git
cd rtl8812AU_8821AU_linux/
make
make install
from https://forums.kali.org/showthread.php?26483-How-to-get-Kali-2-0-to-work-with-my-AWUS036AC-wireless-adapter
however on every boot i have run
cd Download
cd rtl8812AU_8821AU_linux/
make
make install
and reboot for it to recognize my wifi card, does anyone have a solution?
P.S. the interface seems to drop and not list in ifconfig

Same here.
There is something very wrong in Kali 2.0 and strange it isn't fixed by now.
Previous Kali is working -at least this part- Kali 2.0 fails with all FOUR wifi chipsets I tested.
I managed to manually put the wlan in monitor mode ( lot of unnecessarily hassle ) to run into new troubles when I needed another setting.

Fern doesn't do anything either exactly as others posted below. ( Under the previous Kali Fern too works without such problems )

Old version 1.X worked. Fern wifi cracker and other tools. But 2.0 doesn't work.

I am about to purchase AWUS036AC, could someone please kindly confirm if monitor mode and packet injection will work fine with this adapter? will I have issues in Kali 2.0? Thanks.
