After setting airodump to a channel (like usual):
airodump --channel X
It still displayed its status as:
fixed channel mon0: -1
Some forum users advised to use:
airodump --channel X,X
But this didn't work. For the record, I'm using a Thinkpad X60, with the iwl3945 driver. lshw output:
*-network

Here are the commands:
wget http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2010-10-16.tar.bz2
tar -jxf compat-wireless-2010-10-16.tar.bz2

make
sudo make install
sudo make unload
sudo modprobe iwl3945
Alternatively you can also use sudo reboot instead of sudo modprobe if you're unsure which driver module you need to load.
Aircrack should work fine again now. Note that kernel updates might overwrite the module again (and, hopefully, fix the bug at the same time).
Thank you very much.
ReplyDeleteIt works fine!!!

Awesome, appreciate
ReplyDeleteThis doesn't worked for me , but I found another way :
ReplyDeletesudo apt-get remove --purge aircrack-ng
sudo apt-get install libssl-dev
sudo apt-get install subversion
cd ~
mkdir aircrack-ng
svn co http://trac.aircrack-ng.org/svn/trunk/ aircrack-ng
cd aircrack-ng
sudo make unstable=true install
You just have to add this option : "--ignore-negative-one" at the end of aireplay command
ie : sudo aireplay-ng -0 10 -a xx:xx:xx:xx:xx -c xx:xx:xx:xx:xx: --ignore-negative-one mon0
hey i have atheros ath5k and i did both of thease and when i do aireplay it cycles through all the channels and wont stay on the one i need or it when i do airodump-ng wlan0 it wont collect data from a secure network just open???? please help
ReplyDeleteOk.. now my wifi stoped working... aparently using this patch altered some how the wifi driver. Checking the private drivers, it says that the b43 (broadcom card) is installed but not working... after looking up in forums I just gave up, now posting form a fres Ubuntu 10.10 install, hope ya can get aircrack to work..
ReplyDelete--ignore-negative-one works just fine for me....looks kind of ugly but it works and that is all there is...thx anonymous

ReplyDeletenice share! thanks! i used ubuntu 11.04
ReplyDeleteNo patch for Fedora 16?
ReplyDeleteI had the same problem with ath5k driver for Atheros card which supposed to replace mad-wifi. I fixed it by rolling back to old good mad-wifi and deleting ath5k .
ReplyDeleteath5k sucks totally and with mad-wifi I get much better range
