airmon-ng shows nothing

[bredal]

Hi

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!

PID Name
2419 dhclient3
2490 dhclient3
14456 wpa_supplicant
14464 dhclient
14484 dhclient
Process with PID 2490 (dhcleint3) is running on interface wlan0
Process with PID 14456 (wpa_supplicant is running interface wlan0
Process with PID 14484 (dhclient) is running on interface wlan0

Running Backtrack live from USB

From lspci:

Network controller: Intel Corporation Centrino Wireless-N 100

Anyone who can give me any pointers in easy steps?

Thank you for answers

Tried alot of older forumpost with no luck, but found on post which finally did the job.

copy from post:

Here's the instructions that I wrote for someone else with the same problem awhile back.

Uninstall the aircrack-ng suite (airmon-ng is included in this) with this command:
Code:

apt-get autoremove aircrack-ng

Then download the sources from the aircrack-ng website here:
http://www.aircrack-ng.org/
Extract the .tar file with this command:
Code:

tar -xf aircrack-ng-1.1.tar.gz

You will need to update some of the SSL-dev files so run this before building from source:
Code:

apt-get install libssl-dev

Enter the directory that was just extracted and then run:
Code:

make
make install

Reboot and everything should be good to go now.

You need to kill those 5 processes.
Afterwards, do a "airmon-ng check" to verify that they are not there.
Then, put your card in monitor mode.

I have the same issue. However I have a vmware player and running backtrack 5 on it.
What happens is that my HP 6710B wireless works fine in windows. When I start the vmplayer and run backtrack network also works fine but the ip address looks bit odd. I have set up my LAN in 192.168.0.* range whole in the VMplayer it seems to bridge to 192.168.2.* and sets the wireless connection to eth0.
Whe n I try to do some ettercap with the following command.

ettercap -T -M ARP -i eth0 /192.168.0.1/ // ( Trying to check all connections that go trough my router )
I get the following message and then nothing happens.

" 40 protocol dissectors
55 ports monitored

1766 tcp OS fingerprint

So then I start up driftnet besides and on my other laptop I go to google images but nothing shows at all.
Does this has to do with the fact we/I installed on vmplayer or so?
oh and when I check for WIFI it also shows for me nothing in the interface.

Thanks for your help.

Thank you a lot!
I had this problem with Intel Centrino Wireless-N 2230 in my new ThinkPad E430 and this solved it! I spent two days with searching over internet and was almost decided to give up.
Thanks again.
