I'm new to backtrack and linux overall.

My problem is that on my new acer AOD257 netbook airmon-ng don't show any interfaces. My connection however is working for surfing the web etc. ifconfig shows wlan0.

Tried airmon-ng start wlan0 and get following message:

fount 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!

Anyone who can give me any pointers in easy steps?
