Introduction:
This guide will attempt to fix the wrong channel reporting issue many users face on Ubuntu 13.04 (raring ringtail). Typically airodump-ng will report the following:

fixed channel mon0: -1

The odd thing about the above message is that this issue was fixed since the 3.3 rc1 kernel release. Note that 13.04 ships with a 3.8 kernel. I assume this kernel suffers from a regression.

The fix
The easiest way to fix this is to download and install backported drivers from a kernel release that works.
First, let's make sure we have the required headers and tools to install these drivers:

Code: [Select]

sudo apt-get install build-essentialNow we have to download and extract a stable backports tarball, I found version 3.10.4 to be working:

Code: [Select]

mkdir ~/backports
cd ~/backports
wget https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.10.4/backports-3.10.4-1.tar.bz2
tar jxvf backports-3.10.4-1.tar.bz2
cd backports-3.10.4-1
This tarball includes much more than drivers for wireless adapters, but we only need to compile the modules for the wireless subsystem.

Code: [Select]

make defconfig-wifi
makeIf everything went fine, your new modules should be ready to be used. Let's install them:

Code: [Select]

sudo make installNo worries, your original drivers are still there, the system will simply prefer these new ones.
The easiest way to get your freshly built drivers working is to reboot.
Once rebooted, make sure the system is indeed using the new drivers:

Code: [Select]

lsmod | grep compatIt should return a line that's similar to:

compat                 14155  4 bcma,cfg80211,brcmsmac,mac80211

The above procedure you will have to do once.

Let's add a monitor interface for our device (change wlan0 to the interface name your device has):

Code: [Select]

sudo airmon-ng start wlan0This will add an interface usually similar to "mon0".
We still have to stop the network manager service, or the reporting will be wrong:

Code: [Select]

sudo service network-manager stop
sudo killall wpa_supplicantYou should be all set now, fire up an airodump-ng monitor session on a single channel and see if you still get the annoying -1.

You can restart network-manager with:

Code: [Select]

sudo service network-manager start
In case you want to return to your original drivers:

Code: [Select]

cd ~/backports/backports-3.10.4-1
sudo make uninstall
I hope this will be useful, enjoy!

s0ullight,

Thanks for sharing this.

Code: [Select]

make defconfig-wifi or

Code: [Select]

sudo make installDone:

[int3]

I can't unistall! now I have huge lags.

Code: [Select]

make[1]: *** No rule to make target `unistall'.  Stop.
make: *** [unistall] Error 2

[misterx]

I don't think there is an uninstall. By the way, there is a typo, you're missing the 'n' after the 'i'.

[smd]

I followed this guide to the exact description, however these are the results after the "make" command is given. Towards the end it goes on about "error 2" a lot and some "Error 1". Suggestions?

Maybe you need to switch libnl versions. If you have 1, use 3 or if you 3, try one. I know 2 doesn't work with aircrack-ng and that might be it.

[SWAY]

I wanted to share with everyone the reason Ubuntu causes the "negative-one" issue and a simple fix:
I've notice that Ubuntu sets the wifi interface (not the monitor) to channel -1 to scan for available APs but then leaves the interface in that channel.  While you are using aircrack-ng to listen to hanshakes, set your interface down ("sudo ifconfig wlan0 down" replace wlan0 with your interface dev if different) just prior to sending your deauthorization packets.  This forces aircracking to bring up your interface with the correct channel prior to sending your deauth. packets.
I know it's not a "Real" fix to the problem, but it is an effective one.

[misterx]

Killing network managers fixes it.

can someone help me ?

I just saw that post. Use the latest version of the backports, not some ancient one.
