Auto-NDISwrapper/Getting WPA&WPA2 support for AWUS036H in managed mode
Initially I was only going to start a thread to notify people of this handy script that will automate the whole installation process of ndiswrapper for several wireless cards. The script is intended to make the procedure easier by automatically downloading the appropriate drivers for your card and installing them.
Lately there have however been quite a few posts asking for specific directions on how to use ndiswrapper along with the popular AWUS036H wireless card (Alfa 500mw). As many of you without doubt already are aware of the default drivers included for this card does not support connecting to WPA/WPA2 encrypted APs and the only possible way to do this at the moment is by using ndiswrapper. For most wireless cards auto-NDISwrapper will make any tutorials obsolete due to the simplicity of the process, but there is still a bug in the current version of the script preventing it to fully work with the Alfa card. Because of this I changed my mind and chose to convert the announcement into a brief step-by-step guide on how to use the script using the Alfa card as an example.
First of all we will need to download the actual auto-NDISwrapper script, as it was released merely a few days ago and therefore naturally is not included in BT3F. The script can be downloaded at the following location: http://easylinuxwifi.org/
Once downloaded to a location of your choice unpack the file using the following command:
Next make sure that your Alfa card is properly connected to your computer and then cd into the newly created directory and start the script using:
tar xvzf Auto-NDIS-0.1.tar.gz
This will start the installation process and you will want to follow the given instructions from this point onward. If you have an internal wireless card beside the Alfa card you need to make sure to choose u at the first prompt asking:
Next you will notice that the script tells you to manually download the driver from a location which does not exist. Open a second terminal window and use the following command to download the correct windows driver:
Setup (w)ificard or setup your (u)sbcard?:
After downloading the file unzip it using:
Since auto-NDISwrapper wants us to manually place the .inf along with the .sys file into a specific location we copy the appropriate files from our recently created directory. The following commands will take care of that:
Now that we have the driver in place lets go back to the terminal running Auto-NDISwrapper and hit [ENTER] to complete the installation.
cp rtl8187.sys /tmp/auto-ndis/0bda\:8187/
cp Netrtuw.inf /tmp/auto-ndis/0bda\:8187/
To actually use the ndiswrapper driver along with our Alfa card we will only have to unload the r8187 driver and load the ndiswrapper driver instead.
You will now be able to connect to your WPA/WPA2 encrypted AP using the method of your choice, I personally tested both Wireless Assistant and wpa_supplicant. If the interface does not show up at once try unloading and reloading the ndiswrapper driver.
To get back into monitor mode and to be able to inject you will naturally have to revert back to the default driver.
Naturally the same result could have been achieved simply by using the already included ndiswrapper in BT3F, but as the script will make the process much simpler for a growing number of cards I chose this approach to make potential users aware of its existence.
Following the instructions, have questions.
I tried following the instructions. I have questions along
with my results so far.
Should this matter if I am booting from a USB memory stick instead
of a CD?
I assume I am suppose to have an ethernet cable connected
to my router for Internet access for it to download the drivers?
I didn't but thought about this later.
I downloaded them manually and copy them to my 2gig memory stick
which is what I use to boot backtrack 3.
I used (in Windows XP) winrar to unzip everything to my usb memory
stick. I noticed you mentioned what I am guessing to me a linux
unzipping command? Was it OK the way I did it? I seem to be
able to see the .inf file and rtlxxxxx file.
Doing my best to navigate through directories by copy an paste,
I think I got it to the right directory. It appears to do something
by asking me if my device is working. Other than doing a airmon-ng
I do not know what else I should do to know if it's working.
airmon-ng just shows eth1 my internal adapter.
Am I getting close to this installation?
If I ever get it right, would this be now installed
on my usb memory stick so I can use it on other laptops?
Has anyone done all of this and uploaded a working backtrack 3 ISO?
