TroubleShooting: airmon-ng with wlan1

Hi, So Guys yesterday I was working on kali and faced an error.
Code:

Code:

---

root@kali:~# airmon-ng start wlan1

---

and the Result was:

Code:

---

Found 6 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!

So Can anyone plz help me sort this out.

Sadly have exactly the same problem with my rtl8187. It worked wit no problem in kali 1.1a but now getting same error as you in Kali 2.0.
I have read on some other forums that it could be fixed with linux backports aka compat-wireless drivers but not sure how to do it and not mess up my system.

Not sure if it would be possible to extract drivers that used to work in 1.1a and install them in 2.0 since it's a different kernel but maybe some of the other more experienced linux & kali gurus here can advice us and help us.

Ok ... I have found the solution and it worked for me.

You need to run 'airmon-ng check kill' before trying to enable monitor mode.
You DO NOT have to pull the interface down.

Code:
airmon-ng check kill
airmon-ng start wlan0
airodump-ng wlan0mon

I had a similar problem with my Alfa AWUS036NH using wlan0. I have Kali Linux rolling 64-bit running in VirtualBox.
I solved it by changing my VirtualBox 5.1.22 USB Settings to filter for and automatically capture the WiFi adapter [Ralink 802.11 n WLAN (0101)] as a USB 3.0 (xHCI) Controller.
I am posting this because I haven't seen this answer anywhere else.
