Intel Wireless Wi-Fi 5100 Card injection

[Mirus]

Hello,
I have a Dell Studio 1537 notebook with a Intel Wireless Wi-Fi 5100 Card. This card is supported by BT4 but the injection mode isn’t supported. I found a forum witch says: „In order to get injection working on Intel 5100 card download the latest linux-2.6.27-rc7.tar.bz2 kernel and patch the iwlwifi driver with the diffs from the latest kernel iwlwifi driver changes from Stefanik Gábor here”
link: tinyshell.be/aircrackng/forum/index.php?topic=4217.0

So my question: How to change the iwlwifi driver in the BT4?
Thank you for help!

There is a package in the repository named firmare-iwlwifi. That package and some help from google should be of some help. I don't think you need to compile a kernel on your own to get it working, though.

There's no need to download a patch. According to the changelog for kernel 2.6.28 the iwlagn driver supports injection w/out patching for Intel 5100 cards. BT4 uses 2.6.28.1 kernel. They do have a note about 5100 cards you might want to check out near the bottom of the link I provided.

Note: To inject management frames with encryption, HW crypto support
must be disabled using the "swcrypto=1" modparam (or "swcrypto50=1"
for iwl5000). Otherwise most management frames won't be transmitted.

ok, now where would these switches be? im a bit lost here

Do you have a file /etc/modprobe.conf (might also be called discover-modprobe.conf)? If so, you could try to put options iwl4965 swcrypto=1 (or whatever fits your laptop) in there.

[larryhaja]

According to the aircrack-ng.org website you need to pass pass the arguments to /etc/modprobe.d/options file.
http://www.aircrack-ng.org/doku.php?id=iwlagn
For 4965 card is says run

# echo options iwlagn swcrypto=1 >> /etc/modprobe.d/options

For 5100 card I would assume run

# echo options iwlagn swcrypto50=1 >> /etc/modprobe.d/options

Then reboot. I can't confirm that this works as I don't have an Intel 4965 card or 5XXX card to test.
Alternatively, if you just wanted to check to see if it works without making changes to the options file you could load and unload your driver.

# modprobe -r iwlagn
# modprobe iwlagn swcrypto50=1

Hi there larryhaja and thank you for your answers.
I followed your instructions shown above and my iwl5100 still can't inject. I'm using BT4 and everything works great, except injection. I'll be very thankful if you or someone else can help me with this issue.
Thanks in advance.

Hi all ,

First,sorry for my bad english, i'm not english.

I follow the instruction of Alex88, but my Intel 5100 cards have some problems to inject. When I test my card i can see

For information, no action required: Using gettimeofday() instead of /dev/rtc
13:04:04 Trying broadcast probe requests...
13:04:04 Injection is working!

and 3minute latter : the injection doesn't work. When I test aireplay-ng -3 i can see

What can I do to repair this bug ?

Thanks,

yes i have the same problem, but im to stupid to follow his instructions i dont understand certain steps. Would sum1 be nice to explain it, like a tutorial?

I patched the 8.10 Kernel with an injection patch for AGN Cards!
