Airodump, fixed channel mon0 -1

Intel Corporation Centrino Advanced-N 6235 fixed channel mon0 -1?

I am not new with aircrack but i bought this Samsung Series 7 Chronos and installed Kali on it. But when i start sniffing with airodump it always says that mon0 interface is at -1 channel.

I tried the compat-driver after applying on next reboot i got this black screen of death, any help for making running Intel Corporation Centrino Advanced-N 6235 with aircrack?

Thank you.

(Sorry for my bad english, i'm trying my best, it's not my first language)

Did you try to fix your own channel with iwconfig ?

Code:

sudo iwconfig channel 5

Also, try a little mac-address reset :

Code:

sudo ifconfig wlan0 down sudo ifconfing hw ether 00:00:00:00:00:00 sudo ifconfig wlan0 up

Make sure you're not connected to a network while running airodump.

You could also try getting the latest version of Aircrack-ng from the subversion repository and use the option --ignore-negative-one.

airodump-ng --ignore-negative-one

this might help, I've heard of alot of people getting this error, It is a known bug. It might be your wireless card.

try this to test injection:
aireplay-ng --test mon0

Good Luck

Finally it works!. I updated my wireless card drivers with the ones from http://drvbp1.linux-foundation.org/~...tml/backports/ . Also, y used the --ignore-negative-one option and it seems everythings ok now.

Thank you all for your answers!

I will be very interested as I have the same model as you by a little explanation of what you have done to update wireless car drivers with backports and which version of backports, have you used?

Thanks

I downloaded the latest drivers from backports: http://www.kernel.org/pub/linux/kern...-rc3-1.tar.bz2 . Then i extracted the files and followed the instructions inside to install them. After that airodump-ng still shows the -1 channel value, however by using --ignore-negative-one option it seems that now works just fine.
Furthermore, and to make sure everything was good, i tested it with gerix wifi cracker. Before backports driver installation gerix did not work correctly, but after this it managed to work well. At the end i could solve my main issue (the one i did not mention in the main post): capture my wireless network handshake (maybe it captured it or maybe not, anyway i couln't notice because the -1 channel value).

Sorry if i wasn't clear enough, i'm still practicing my english :). Hope this can be useful in someway to you.

And, another thing. Since you have the same laptop model as me, i wonder if you have managed pyrit to detect your gpu using list_cores command? Apparently, for some weird reason, Pyrit, and Oclhashcat can't detect my gpu drivers (Radeon HD 8770). Also, when i use aticonfig command i get: "aticonfig no supported adapters detected". Do you know how to solve this issue?

The following post fixed it for me: https://forums.kali.org/showthread.p...rror-1-channel

Reposting details here, to make it easier to find for people having the same issue. (Google turns up loads of questions, few solutions.)

Basically, when you start up airmon-ng, you might see something like this:

Code:

Found 3 processes that could cause trouble. If airodump-ng, aireplay-ng or airtun-ng stops working after a short period of time, you may want to kill (some of) them! -e PID Name 2796 NetworkManager 2846 dhclient 2352 wpa_supplicant

You will see the same thing by executing airmon-ng check. I was hesitant to kill those processes, thinking that might cause some other issues, but I'm working in a VM, so in the end, I just went for it, using the airmon-ng check kill command:

Code:

root@kali:~# airmon-ng check kill (same as above, then...) Killing all those processes...

That fixed my problem with the interface being locked to channel -1, and so far, everything is working fine!
