Please help: 3945ABG wireless not working

[adamh128]

I have installed BT3 beta on HDD, but I'm having problems getting my 3945 to work.

Following this advice on an old thread:
3945abg works perfect in bt3.

just unload the normal drivers (modprobe -r ipw3945 or iw3945 i dont remember now..)

write:

cd /usr/src/drivers/ipwraw-ng/
make
make install
modprobe ipwraw

thast it!

now if you write iwconfig you have the wifi0 and rtap0 interfaces to use with aircrack-ng suite!!

also now you can adjust the channel and rate of your card:

iwconfig wifi0 rate xM
iwconfig wifi0 channel x

go crack now!!! :)

The make install works ok for the raw drivers, but I get the following error for modprobe:

#modprobe ipwraw
FATAL: Error inserting ipwraw (/lib/modules/2.6.21.5-smp/kernel/drivers/net/wireless/ipwraw.ko): Invalid module format

Any advice how to fix this?

Thanks.

The drivers you need are all ready installed on bt3 to fix the menu links check the bug&fix section for my fix. Then you can load and unload from the kde menu.

I fixed the KDE menu as suggested but I get:

FATAL: Error inserting ipwraw (/lib/modules/2.6.21.5-smp/kernel/drivers/net/wire less/ipwraw.ko): Invalid module format
No modules unloaded.
insmod: error inserting 'compatible/iwl3945.ko': -1 Invalid module format
Load failed.

Try reinstalling the drivers and if that doesn't help reinstall BT3. It may be worth checking if the BT3 download isn't corrupt... ie. check that the md5 sums match, if you haven't already checked.

do not load or install any thing , ipwraw and iwl3945 are already install in bt3 ,

try this :

1- modprobe -r iwl3945

2- modprobe ipwraw

then
3- ifconfig wifi0 down
4- macchanger --mac 00:11:22:33:44:55 wifi0
5- ifconfig wifi0 up

and

airmon-ng start wifi0

i think it's will work with you this time , i have the same intel 4945 wireless card and it's work with me so great , injuct and replay everything ,,,

note : do not install or load any drive couz it's already installed in bt3 :)

If you type in a light color some of us that use the white skin may never see your post --purehate


I found this in the boot log (dmesg):
iwl3945: version magic '2.6.21.5 SMP mod_unload 486 ' should be '2.6.21.5-smp SMP mod_unload 686

Looks like it might be the problem - any ideas how I fix it?
Thanks.

If you're using BT3 beta you should check the BT3beta Bugs & Fixes (http://forums.remote-exploit.org/forumdisplay.php?f=34)
section for possible solutions.

Example: this is to fix the menu items: taken from the Bugs section of the Wiki here:
http://backtrack.offensive-security.com/index.php/Bugs#Incorrect_menu_items

Incorrect menu items

Backtrack>Radio Network Analysis>80211>Misc
Fix:
Load IPW 3945/4965Command: modprobe ipwraw && rmmod ipwraw & load && cd /root;sudo -s
Workpath: /usr/src/drivers/iwlwifi-1.0.0/
Load IPWRAWCommand: unload && modprobe ipwraw && cd /root;sudo -s
Workpath: /usr/src/drivers/iwlwifi-1.0.0/

You can also check the wiki >>

There are a lot of threads covering the ipw3945.

You can use the Search Function (http://forums.remote-exploit.org/search.php) and search for ipw3945 to find them.

Good Luck ;)

{HARD}, I was having the same problem with my wireless card and your post helped me. Thank you. While I am very greatful that it is working, im not satisfied with the solution so much as understanding what was wrong and how I fixed it.

Would it be possible for someone to explain what was wrong and how those commands fixed it.

Greetings Captains!

Sorry for Invading this Thread, but i'm new to these forums, i've sent a PM to an Administrator, but i still have a problem.

I am a software developer, and a <backtrack enthusiast>.
BT2 worked fine for my laptop, but it no longer works with BT3 (initrd hangs at boot)

I want to start a thread in the BT3 beta section -- non working hardware, but i always get the message that i cannot post because my account is being verified.

Was this my fault? Is this normal?

Please enlighten my path :)

Cheers,
Phk

Firstly don't double post. If you had read the rules and the welcome email you would know that your first few posts are moderated. I think it also takes 3 days to become a full member.

Please read the rules now... the forum rules are very clear on some very important things.

Otherwise welcome and enjoy your stay. :)

btw. I think I answered your question on your other post. ;)

I've understood the rules now :)

Thank you. I'll reply in my thread.

Alright, so I've fixed the menu items for loading and unloading drivers, and I can't connect to the internet or drop my card into monitor mode and use kismet. However, I'm having a slight hiccup.

My AP is set to WPA2, and after loading the drivers, the first time I try to connect, it always fails. After that, I have no problems upon trying to connect a second time.

As a semi-separate issue, setting the auto-connect option via the wlan assistant results in the connection popping on and off every 2 seconds until I bring down the interface.

I tried Googling the issue, and I came up with the following bug report:

h t t p:// w w w. intellinuxwireless. org/bugzilla/show_bug.cgi?id=1589

The only problem with that was that it was in Debian, and backtrack doesn't have the ifup command so I don't believe I can implement his workaround. I'll continue to do research. In the meantime, suggestions?
