Aircrack-ng (fixed channel mon0: -1)

Everyone knows the message: "fixed channel -1" on aireplay, in previous versions of Ubuntu 10.10 didn't happen, so we probably think in create a new partition only for the aircrack, but there is an easier solution, consist in patch the aircrack, cause the aircrack don't recognize your wlan driver. To install it:

We open a terminal and type:

sudo apt-get install linux-headers-$(uname -r) 

Now download the newest patch in http://linuxwireless.org/en/users/Download/stable and uncompress it in our home folder.

In the terminal again, we type:

cd (location of the file uncompressed)

Now, we download the patch, typing:

 wget http://patches.aircrack-ng.org/channel-negative-one-maxim.patch

and now install it:

  sudo apt-get install patch

Apply the patch:

patch ./net/wireless/chan.c channel-negative-one-maxim.patch

And we open this file in the terminal again:

gedit scripts/update-initramfs

Search: #*** line 13: KLIB=/lib/modules/2.6.31-wl/build #*** And placed it with : KLIB=/lib/modules/$(uname -r)/build 

Close gedit and save, then type in the terminal:

make

Then:

sudo make install

and then:

sudo make unload

And finally:

sudo reboot

Now everything's ok, but it's possible that the name of our wlan chipset has changed, so we type:

sudo iwconfig
