Help with Backtrack5r3 Wireless card problem

I installed backtrack5r3 64bit gnome on my macbook (10.9) through VirtualBox, and I ordered a wireless card to get it going. I chose Awus036Nh(RT3070 chipset, I am sure it is compatible with backtrack5r3, and i also checked), and it had a CD with it for the driver setup. I pulled the driver out and use the "make" command to get it installed, and it was successful(at least by its look).

However, the first problem I faced is that the USB does not appear in VirtualBox, even though usually every USB plugged in the laptop should appear in the bottom-right corner, including the mouse, trackpad. If I plug it in before opening virtualbox, it works in mac(the utility window pops up), and if i continue with virtualbox, though it does appear, if I click on it I get an error "someone else is using", because it is configured so if I want to have the USB in virtualbox not in the host, I have to plug it in after it is opened.

I looked for many threads, posts and youtube clips, but I can't find any tutorial for Awus036Nh, but for Awus036H(rtl8787l chipset), the more popular wireless card, and the driver is different, so it was not much help. It works on my host os(mac), and it can be detected by vbox(i've used the usb filter as all tutorials instruct, and also installed the extension pack) if i plugged it in earlier, so I am quite sure that nothing wrong is either on my mac, the card or vbox itself. Maybe I missed some steps during the configuration, can someone help with that? It will be great if someone can show me the clear steps, and probably also a clean copy of the driver.

Re: Help with Backtrack5r3 Wireless card problem

The below steps were given on many websites on how to use the Awus036Nh with Backtrack 5 r3:

Quote:
Step 1. The chipset needs to be a Realtek rtl8187.
Lets run: root@bt:~# airmon-ng
Interface Chipset Driver
wlan1 Realtek RTL8187L rtl8187 - [phy0]

Okay, all good so far:-)
Step 3.
Now we need to load the rtl8187 driver.
Lets run: root@bt:~# modprobe rtl8187
Step 4.
Now we need to make sure that our wifi adapter is turned on.
Lets run: root@bt:~# dmesg |tail -20

Please notice how our rtl8187 driver is turned off But this error is quite common so we to need to force our card back into an enabled state.
Step 5.
root@bt:~# rmmod rtl8187
root@bt:~# rfkill block all
root@bt:~# rfkill unblock all
root@bt:~# modprobe rtl8187
root@bt:~# rfkill unblock all
root@bt:~# ifconfig wlan1 up
lets check ifconfig
Step 6.
root@bt:~# ifconfig
And we now have a wireless interface that we can use and we are almost done. We have a wirless interface yes, but in order to use the tools such as aircrack-ng or wepcrack we need to put our Alfa Awus036H USB Wifi Adapter in monitor mode so we can utilize backtrack's wifi tools.

Step 7.
root@bt:~# airmon-ng start wlan1
Found 4 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
860 dhclient3
914 NetworkManager
1092 wpa_supplicant
2220 knetworkmanager


Interface Chipset Driver

wlan1 Realtek RTL8187L rtl8187 - [phy1]
(monitor mode enabled on mon0)
Lets check ifconfig again.
root@bt:~# ifconfig

Notice how we have a new interface mon0!
This is our monitor mode that we need to utilize tools such as aircrack-ng and wepcrack.
Run this command to find available wireless networks:
root@bt# airodump-ng mon0
