Intel iwlwifi drivers with injection * WORKING with 3945 & 4965 cards *

[freon23]

i've disabled the rf switch support in Networking  ---> < >   RF switch subsystem support , but the message about disabled radio appears still in the log. I've been looking into the Device Drivers  --->\[*\] Network device support  ---> Wireless LAN  ---> Intel PRO/Wireless 3945ABG/BG Network Connection too, but there is no configuration option for the switch. Grep didn't find any other relevant lines with keyword RF, so I assume configured the kernel correctly.
I don't know, if it is relevant, but if I push the rf switch button to turn the wifi off, this appears in my dmesg:

usb 1-1: USB disconnect, address 2

and if I turn it on again:

hub 3-0:1.0: unable to enumerate USB device on port 1
usb 1-1: new full speed USB device using uhci_hcd and address 3
usb 1-1: configuration #1 chosen from 1 choice

The same lines as above used to appear while using any kernel (2.6.22-2.6.25).

That certainly looks weird. I guess you should post that on the linux-wireless mailing list.

[freon23]

.NetRolller 3D: Thanks for your time and patience indeed, I'll post into the mailing list as you suggest.

Do you have any bluetooth chip in your computer? that might be it...

[freon23]

JMF: Yes I have. You are right, this explains it: Bus 001 Device 003: ID 03f0:171d Hewlett-Packard Wireless (Bluetooth + WLAN) Interface [Integrated Module]

Has anybody got a guide on getting this working on ubuntu. Im abit confused as to what i need to install.

[.NetRolller 3D]

Ryanmt: it works on ubuntu, as long as you know how to update the kernel (Ubuntu has 2.6.24, but at least 2.6.25 is required). Joker has posted instructions on this.

Thanks for .NetRolller 3D. It was extreamly useful the information you gave me. I can start iwl3945, but I use ipwraw for injection because iwl3945 can't get an association (ACK) in my computer. However, I use iwl3945 for everything else. I sometimes need to restart the  iwl3945 driver (rmmod and modprobe) because it stops running well, I can't understand its behavior but I can set it up opening ipwraw before and starting a capture with ipwraw, then the message "no such device" is not showed so I can use my iwl drivers normally...
I am not a professional user but I try to keep improving.

Thanks for all contributors.

alezmad: did you install all patches correctly? Do you have 2.6.25 installed? (2.6.24 won't work, not even with the compat package!)

Also, use the 2008-05-20 version of compat-wireless, as iwlwifi is changing rapidly in later versions, due to the new iwl5000 card. I will post a patch for the new version once things calm down in iwlwifi.

[alezmad]

Thanks .NetRoller3D.
I gonna install 2008-05-20 version.

Perhaps you used the wrong -p or --strip option?

File to patch: ^C

I can patch it by hand but I'd rather doing it automatically.

Patch the compat package, not the kernel. The patch looks like a kernel patch, but it isn't.

[alezmad]

I extracted the compat package, after that I patched the package using the extracted folder. My kernel is here "/lib/modules/2.6.25-ARCH"
So I think I use the patch correctly.

Why doesn't the patch work properly? I used the versions which you recommended me.
Note that some hunks were succeded and I use this command "patch -p5 -i iwlwifi-injection-2.6.25.patch" in this extracted directory "/home/alezmad/Desktop/compat-wireless-2008-05-20/compat-wireless-2008-05-20/drivers/net/wireless/iwlwifi" where iwl3945-base.c and others are located.
"patching file iwl3945-base.c
Hunk #1 succeeded at 2542 (offset -203 lines).
Hunk #2 FAILED at 2585.
(...)"

If there isn't any other option, I can patch it manually.
Thanks NetRoller for your useful help.

[.NetRolller 3D]

Oops... I meant it the other way around. The patch you were using is for the "bare" kernel, without the compat-wireless package. If you use that, then compat-wireless is not needed at all. However, don't forget that 2.6.25 needs the 2.6.24.4 version of the frag patch - the 2.6.25-wl one is only for 2.6.25-wl and compat-wireless, not for the regular 2.6.25.

[alkar]

Firstly, many thanks and kudos for the work on iwlwifi guys!

No on my problem, I have an iwl3945 using kernel 2.6.25. I applied the 2.6.24.4 fragmentation patch and the iwlwifi-injection-2.6.25 patch on the bare kernel, rebuilt the modules and still no luck at getting packet injection.

Have I got it all wrong?
Do you need me to supply other info?

[.NetRolller 3D]

alkar: do you use 1.0-beta2 or newer? Older versions won't work, due to the lack of radiotap support.
