I'm having big issues here. My Alfa AWUS036H just won't play well with BT5.

I'm running BT5 in VMware on OS X.

the problem is, when I type to start wlan0 up for airodump-ng it errors a lot.

Code:
root@bt:~# airmon-ng stop wlan0


Interface	Chipset		Driver

wlan0		Realtek RTL8187L	rtl8187 - [phy0]
				(monitor mode disabled)

root@bt:~# ifconfig wlan0 down
root@bt:~# macchanger --mac 00:11:22:33:44:55 wlan0
Current MAC: 00:xx:xx:xx:xx:xx (Alfa, Inc.)
Faked MAC:   00:11:22:33:44:55 (Cimsys Inc)
root@bt:~# airmon-ng start wlan0


Found 2 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
995	dhclient3
1817	dhclient3
Process with PID 1817 (dhclient3) is running on interface wlan0


Interface	Chipset		Driver

wlan0		Realtek RTL8187L	rtl8187 - [phy0]
				(monitor mode enabled on mon0)
first what are those:
PID Name
995 dhclient3
1817 dhclient3
Process with PID 1817 (dhclient3) is running on interface wlan0

Second, why does it say: (monitor mode enabled on mon0) never seen that in BT3.

Hope you can help a friend in need
