Set wifi card to monitoring mode

Solved

Hello.
I can't get my Linksys WMP300N card to switch to monitor mode.
Airmon tells me that monitor mode is not supported:

usage: airmon-ng <start|stop> <interface> [channel]

Interface Chipset Driver

wlan0 Unknown ndiswrapper (MONITOR MODE NOT SUPPORTED)

I can't find any monitoring driver for this card.
Yet it has an Atheros chipset...
Maybe there's a solution to my problem?

For your information (if it helps), my driver version:
Version]

Signature = "$CHICAGO$"

Class = Net

ClassGUID = {4d36e972-e325-11ce-bfc1-08002be10318}

Provider = %Linksys%

Compatible = 1

DriverVer = 09/11/2006,6.0.2.9

Catalogfile.nt = net5416.cat

;Catalogfile = net5416.cat

there you go
Configuration: AMD 64x2 Linksys WMP300N PCI card Linux Ubuntu 6.10

    Hello,

    You don't have to use airmon-ng to enable monitor mode!!! Iwconfig can do it just fine:

    ifconfig ath0 down
    iwconfig ath0 mode monitor
    ifconfig ath0 up
    airodump-ng ath0

    Impossible with Atheros!!! It's one of the few chipsets where you can do injection on Windows.
    So if it doesn't work on Linux....

    ps: man iwconfig (section MODE: managed, master, repeater, monitor, secondary, master).

      Hello!

      You made some mistakes, but it’s not a big deal...

      ifconfig ath0 down
      iwconfig ath0 wlandev wifi0 wlanmode monitor
      ifconfig ath0 up
      airodump-ng ath0

    ifconfig eth0 hw ether 00.11.22.33.44.55
    nmap
    hping
    etc etc ..

    MAC filtering is unfortunately useless.

    As for the brute force attack, you just need it to crack the key. With 2,000,000 IVs, it goes quickly.
    As you said, what will slow it down is the MAC filter. Just a little bash script that sends "who is ..." and waits for the response.
    Once done, a continuous ping and you get the IVs very quickly.

    it's true but that's a question of responsibility to take.
    and if it doesn't harm the person, I don't see any reason to go to court or anything...
    if she asks me to stop, then I stop.
    it's not because the law punishes something that it's wrong.

    there you go

    Well, your card doesn't seem to be supported even though it's an Atheros chipset. Is it for Whax or Backtrack that you want to do this...

    You tried:
    airmon.sh

    Yes, but it doesn't work:
    climu@pc-climu:~$ airmon.sh
    bash: airmon.sh: command not found

    and before I tried with airmon (not -ng)
    but it told me the same thing: "monitor mode not supported"
    and what does the .sh do, by the way???
    because under troppix, you have to type airmon.sh
    whereas under ubuntu airmon ...

      Hi man,
      I have a problem with my wifi card. I'm using Ubuntu and I can connect, just to let you know that it works and everything. But the problem is that if I try to switch to monitoring mode, it says it's not supported.
      If I run iwconfig my_card, I notice in the chipset column it says Unknown and in the driver column it says wl. I don't understand any of this. Can you help me?
      My card is: Dell wireless 1397 wlan Mini-card
      I would like you to reply to the following address

      Thank you in advance.........

      Hello, to execute a bash script under Linux, it's ./airmon.sh.

    hacking WiFi is bad.
    also, your card doesn't support monitoring, let alone packet injection.

      Hacking Wi-Fi is bad, but checking if your Wi-Fi system seems more or less secure is good! One shouldn't see hacking everywhere.

    a Wi-Fi network is not protected in any way, even with an encrypted WPA v2 key and all that you want. Instead of taking 5 minutes, it will take you 10 ;)
    there is only the RADIUS server left omg

      Completely agree, but a WPA2 that cannot be easily cracked by brute force like As.,$Erc!§ec487E etc... should be changed once a month)... with MAC address filtering, a fixed IP range (No DHCP), and a non-visible SSID will deter more than one unless you have a professional hacker as a neighbor, you won't risk much.

    This confirms what I said earlier: unless you have a neighbor who knows quite a bit about it, you’re not at much risk. I’ve done a study on it, and it’s important to know that more than one third of WiFi connections are absolutely not secure, so who is going to bother hacking you when the neighbor next door is wide open? I have proof of this from my neighbor on the left, who I went to visit last week and showed him his setup!

    I believe the fault also lies with the ISPs who almost always offer WEP by default, lol.

    That’s for sure, a good little Lynksys or Cisco router (much more expensive) is definitely better.

    it's simply impossible...
    and besides, I don't agree that hacking wifi is bad...
    if you just check your emails it doesn't change anything for the other person.
    it's just a stupid notion of ownership.
    however, it's against the law.
    but morally, I don't think it's bad...
    anyway, thank you for telling me it was impossible, it will save me from searching in vain.

    Attention, toujours sur la même étude que j'ai réalisée, je me suis tourné du côté de la loi, donc pour une intrusion informatique, c'est 3 ans ou 300 000 € d'amende, ça fait cher pour relever 5 adresses par jour, non ?

      Hey yeah, but the neighbor in question still has to prove that "X" stole their WEP key! Especially since it's very easy to change your MAC address so that it doesn't match your own hardware. Good luck proving anything with that!

    Problem solved: In principle, it is impossible.

    nothing is impossible, however I really doubt that anyone could break a WPA2 key (unless it is poorly thought out ... like "pierre rides a bike"). whether by brute force or dictionary ...
    what is the maximum length of a WPA2 key?
    what characters can be used to create the key (ascii ...)
    how many possibilities does that make ???
    aside from user negligence in creating their key, the chances are slim!

    Hello,

    Um, I think you made a mistake and I don't believe I've made an error.
    I think it’s rather:

    wlanconfig ath0 destroy
    wlanconfig ath0 create wlandev wifi0 wlanmode monitor
    ifconfig ath0 up

    So you either go through iwconfig or wlanconfig, but the madwifi drivers don’t like iwconfig too much anymore.
    I'll still test your solution...

    Best regards, Narlotep

      I am on Linux (SUSE 10.3) and I did what was mentioned just before. When I then type iwconfig in a terminal, I can see that my wifi card (an Atheros) is in monitor mode, but I need to reboot because the wifi card does not detect anything anymore.
      I reboot and type iwconfig in a terminal again, and now my card is back in "Managed" mode.

      What should I do?

    I find Wi-Fi sharing to be smart, like carpooling; let's not forget that Wi-Fi is a form of pollution (besides, currently there are no studies showing the long-term effects on humans), and it's entirely stupid for everyone in their 30 m² apartment to have their own box with Wi-Fi radiating over the 10 neighboring apartments.

    For my part, back when all the boxes were WEP, I used to crack a lot of networks for friends.

    Otherwise, to answer the question, change your Wi-Fi card, it'll be quicker! Check out this link, the bible: http://www.tuto-fr.com/tutoriaux/tutorial-crack-wep-aircrack.php

    Good luck

    Hello,

    I have almost the same problem, my wifi card can't switch to monitoring mode. I just want to know if it's actually compatible with this mode. My card is a Broadcom 4313 802.11 b/g/n; I don't know if this information is enough.

    Thank you in advance.
