    [Question] Patching the ath5k driver for injection

    Well First time posting.

    Well, I just got myself a new netbook today. It's an Acer Aspire AOA150-1555 and have installed Ubuntu 9.04 on to it. Basically what I want to do is patch my wireless card for better injection, But that's where I'm hitting a wall.

    Code:

    I have downloaded the driver to patch it from the aircrack-ng site. (ath5k-injection-2.6.27-rc2.patch), but now I'm stuck as I'm not sure where the Ath5k sources are at on the system. This was easier on my old sylvania g netbook as there were a lot of tutorials on how to patch the r8187 driver. but running ls -a /usr/src/linux-headers-2.6.28-11/drivers/net/wireless/ath5k/ I get

    Code:
    owner@ubuntu:~$ ls -a /usr/src/linux-headers-2.6.28-11/drivers/net/wireless/ath5k/ 
    .  ..  Kconfig  Makefile
    I was wondering were the sources are or better yet if a tutorial was avaiable about how to patch the ath5k drivers on ubuntu 9.04.

    Thanks in advance to anyone who can help me with this issue

    Re: [Question] Patching the ath5k driver for injection

    Well I have not posted on these forums for a minute, but felt I should help you out since I figured this one out for myself after much head scratching


    You will need to get source code for a package called compat-wireless - Just google compat-wireless and the first hit is it.

    Get the latest stable release of that and then you must get the proper aircrack patch for ath5k injection rates, ath5k-injection-2.6.27-rc2.patch seems to work fine. So google aircrack patches and get that one.

    Once you untar the source for compat-wireless you will find the ath5k source in compat-wireless-2.6.30/drivers/net/wireless/ath5k . Before compileing the compat-wireless code you must patch the ath5k driver source with the aircrack patch mentioned above.

    To do that you use the patch command like so in a terminal

    patch -Np0 -i <name of the patch file>

    Now the patch file will point to a different location than the source is in so it will ask you for what file you want to patch, you need to give it the full path to the source code as well as the source code filename

    Example from a terminal prompt with patch in same folder as prompt is.
    patch -Np0 -i ath5k-injection-2.6.27-rc2.patch

    This returns that it cant find the file to be patched and prompts for file name & location

    So I enter the following for source file location ( via paste )
    /home/tech/CUSTOM-SOFT/compat-wireless-2.6.30/drivers/net/wireless/ath5k/base.c

    where base.c is the source code to patch and the rest is the path to where I have placed the source, you can put your source code to compile in any directory you want etc. I am no Ubuntu expert at doing it the right way - I am good at makin it work though as that is all I care about.

    Once you patch the driver its just these commands in the compat-wireless source directory.

    make
    sudo make install

    Then you will also need to deal with blacklisting any unwanted atheros madwifi modules previously in use etc. So if you don't know how to do that just search here on the forums as it is well covered.

    I also remove Jockey & Network Manager while installing WICD as a GUI replacement that seems to cause less interference than network manager can


    GOOD LUCK ALL AND POST IF YOU GET YOURS TO WORK

    Re: [Question] Patching the ath5k driver for injection

    If you have jaunty and ath5k comes working out the box, do you have to get compact wireless still or just patch the one thats with the system?

    Re: [Question] Patching the ath5k driver for injection

    Since the default install does not include the wireless driver sources, yes you need to get compat-wireless.

    I have followed the guide and it worked for me.

    Does it have to be 2.6.30?

    Ive searched around but I cant seem to find a thread that explains it in depth. Can you please point me to a good one?

    How can you make sure that Network Manager is uninstalled?


    Thats it from me, thanks for all the help thus far regarding patching these drivers.

    Re: [Question] Patching the ath5k driver for injection

    Well, I completed the patch and compiled the patched compat install, then made the install to kernel 2.6.28-14-generic. Now, for whatever reason it does not load. I was able to boot using 2.6.28-11-generic however. The new kernel just hangs after the ubuntu splash screen.

    I am not sure what happened. It all seemed to run smoothly, no errors. I saved the log information of the install. It seems that I have killed that kernel.

    Sweet.

    Yeah, Injection Works out of the box so to speak, about 500 pps!

    I would also like to know if it HAS to be 2.6.30 ? I am using 2.6.28 and I don't want a dead kernel like the poster before me thanks in advance!
