How to use Intel Pro/Wireless 3945ABG in Backtrack 2
October 25th, 2007 by 
Patchy
The Intel Pro/Wireless 3945ABG (IPW3945) is a popular wireless card that is build-in many laptops. However, the drivers included in Backtrack 2 do not allow you to do packet injection. To fix this problem you need to install the IPWRAW drivers. The easy way to do this is to use Backtrack 2 module. A module adds additional components to Backtrack 2. To add a module, you copy the .LZM file into the modules folder in the BT2 .ISO. After adding the IPWRAW module to the BT2 .ISO, boot up Backtrack and click the “IPW3945 RAW load.sh” script on the desktop to install the IPWRAW Drivers. After the drivers are installed your wireless card will be lock in monitor mode, and you will be able to do packet injection with aireplay-ng. If you want to put your wireless card in managed mode and connect to a wireless network click the “IPW3945 load.sh” script on the desktop. That script will load the default IPW3945 Drivers.

hi! i follow the steps in the guide but when i boot my system tell me that cant boot because a Checksum error happens!!! i think thats because i modify the iso file…but i can t fix this error!!! can someone help me???

If you use winISO to build the entire ISO file it will create a checksum error. You have to create a copy of bt2final.iso then open it with winISO, add the module, and save the iso. It doesn’t create a checksum error when you just amend the .iso it does when you build the entire .iso

Hi, I have copied patch into the iso image of Backtrack2 and ait installed itself. However when I tried to fing my wireless card it was no result after using command iwconfig. It said no wireless extension on lo or eth0. It’s strange because I’m connected to the net through wireless card (Broadcom 802.11) and using internet on firefox under Backtrack. I just wanned to try packed injection with aireplay-nd. Can u give me advise how to make my wireless card visible as device in iwconfig ?

How about 2200bg nic? absolutely everything works except package injection.. any ideas?

Check your wireless card’s compatibility here: http://backtrack.offensive-security.com/index.php?title=HCL:Wireless
If your wireless card doesn’t support monitor mode or packet injection your best bet is to buy a cheap USB wireless adapter.

Well…. something is missing in this video… From the time you start Airodump.ng to the moment you log on to the web there is totally darkness… how about collectin those IV´s and how to save them… and later serv them into Backtrack… while working from a live cd… maybe this is an easy task if you have BT2 installed on a harddrive… but the most of us simply cant get acces to any storage media while working from a live CD… Patch this please….
wil my SD cardreader able to work as “harddrive” and can we format this type of card in Fat32 wich should be the best format for Linux ???
All the best and thanks for this waterhole…

The point of this Vblog was not to show you how to crack wep. It was to demonstrate how to use the Intel Pro Wireless 3945ABG in BT2, to show how to use the IPWRAW for packet injection, and how to use the default drivers for managed mode. If you what to learn how to crack wep watch Ep. 2.
It is not necessary to save IVs to a hard disk if you a have enough RAM. Also, I have never tried using SD card with Linux, so you will have to try it yourself. USB thumb drive may work better. Furthermore, FAT partition will work with Linux, but EXT is a more common type of partition for Linux

Hi Pathy,
If a networks ESSID is looking like this 0000000000000000 in Wireshark but apears as a “NO ESSID” in the networklist in Aircrack… what am I going to use in a Fake ID attack as ESSID.

Ohh No,
Your sofware took the backslashes… there must be one for every three zeros.. in the ESSD that I have encountered.
Thanks

I have a toshiba satellite with an INTEL 3945abg Wireless Adapter. For some reason, even after trying the above, I cant get my card to work.
iwconfig will always display no wireless extension. InfinityExists please help

March 20th, 2008 at 2:21 am

March 30th, 2008 at 9:11 pm

I’m getting an error:
No modules unloaded
Uloading ‘ipwraw’ … done
Loading ‘ipwraw’ … done
Waitng for /sys/class/net/wifi0/device/rtap_iface to appear…. time out.
Could not find wifi0 interface.
I am running this out of vmware… is there something specific I need to configure or that I’m missing?
April 18th, 2008 at 7:45 am
Nevermind, answered my own question, w/ vmware only USB dongles are supported.
April 23rd, 2008 at 12:41 pm
for some reason i get the error:
/tmp/ipwraw/load: line 93: ./set_channel: No such file or directory
Could not tune to channel 1.
any suggestions?
April 23rd, 2008 at 1:03 pm
great, but now how do I use it in a vm? LOL.
May 28th, 2008 at 12:31 pm
What about promiscuous mode? Can these driver allow implementation with say, the Intel 2200 b/g? Or will it only allow packet injection? Thanks!
June 3rd, 2008 at 11:11 am
I’m not running vmware and I’m still encountering this problem.
