Monitor mode with TP Link 725N

[Masterjoa]

Hi,

I've just bought a TP Link 725N for Kali linux as a virtual machine.
I installed the r8188eu driver. It works fine... but when I try airmon-ng start wlan0, I get this:

Found 3 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!
-e 
PID	Name
8600	NetworkManager
8604	wpa_supplicant
9864	dhclient
Process with PID 9864 (dhclient) is running on interface wlan0


Interface	Chipset		Driver

wlan0		Unknown 		r8188eu (monitor mode enabled)

But the wlan0 is still Mode:Managed (iwconfig) and there is no mon0.

airmon-ng stop wlan0 doesnt work...

Any Idea ?
