LinuxQuestions.org - backtrack noob needs help

Hardware:
Laptop NB MSI GT780DX-406US RT
I'm trying to use the built-in wireless card because i couldn't get my wireless adapter to work (TP-LINK TL-WN823N - chipset RTL8192CU)

So here's how i'm trying to do it:

- I use VMware v9 with Backtrack 5
- I launch the virtual machine, then start X, then activate the network card device inside vmware
- To enable the wireless card i need to type in the konsole /etc/init.d/wicd start
- At this point, internet is working inside backtrack (i can browse the web with firefox and konqueror)

I'm trying to follow this tutorial here: http://www.rafayhackingarticles.net/...cktrack-5.html

First Login to your Backtrack / Linux distro and plug in your Wifi adpter , Open a new konsole and type in the following commands

ifconfig wlan0 up

where wlan0 is the name of the wireless card ,it can be different .To see all wireless cards connected to your system simply type in " iwconfig ".

iwconfig will give me this result:

lo - no wireless extension.
eth0 - no wireless extension.

but if i type ifconfig, i get this:

Putting your WiFi Adapter on Monitor Mode

To begin, you’ll need to first put your wireless adapter into monitor mode , Monitor mode is the mode whereby your card can listen to every packet in the air , You can put your card into monitor mode by typing in the following commands

airmon-ng start (your interface)

Example :- airmon-ng start wlan0

Now a new interface mon0 will be created , You can see the new interface is in monitor mode by entering "iwconfig mon0" as shown - See more at: http://www.rafayhackingarticles.net/....hk6CzeXJ.dpuf

If i type "airmon-ng start eth0" i don't get any result:

and "iwconfig mon0" will tell me "mon0 no such device"

I'm stuck here. Please help me !
