How to Check if Your Wireless Network Adapter Supports Monitor Mode & Packet Injection

To hack a Wi-Fi network, you need your radio card to support proctor mode and packet injection. not all radio cards can do this, but you can promptly test one you already own for compatibility, and you can verify that the chipset inside an adapter you ‘re thinking of buying will work for Wi-Fi hack. radio cards supporting proctor mode and mailboat injection enable an ethical hack to listen in on other Wi-Fi conversations and even inject malicious packets into a network. The wireless cards in most laptops are n’t identical good at doing anything other than what ‘s required to establish a basic Wi-Fi connection .

While some inner cards may offer some support for monitor mood, it ‘s more common to find that your card is n’t supported for tools included in Kali Linux. I found the calling card in a Lenovo laptop I use to support both, so sometimes it ‘s possible to save by using your home laptop tease for practice when appropriate. If the internal one does n’t support the modes, an external one will be needed. external network adapters average between $ 15 and $ 40 per card. While this may not seem like much, making a err in purchasing a network arranger can add up cursorily and be discouraging when beginning learning about Wi-Fi security.

These devices may seem a little complicated at first, but they ‘re pretty simpleton. Each radio network adapter has a nick inside of it that contains its own CPU. This chip, along with the early circuitry in the arranger, translates signals from your calculator into radio receiver pulses called “ packets, ” which transfer information between devices. Choosing a Wi-Fi adapter requires you to know about a few things, such as the chipset inside, the antenna in function, and the types of Wi-Fi that the card support.

Option 1: Check an Adapter’s Chipset Before You Buy

If you have n’t yet purchased the radio net card you ‘re considering, there are respective ways you can check to see if it supports monitor manner and packet injection before committing to a leverage. Before we dive into those, however, you need to know the remainder between manufacturers, so there ‘s no confusion .

Identifying the Card’s Seller

The seller is, you guess it, the manufacturer selling the network adapter. Examples include TP-link, Panda Wireless, or Alfa. These manufacturers are responsible for the forcible layout and invention of the adapter but do not produce the actual CPU that goes inside the adapter .

Identifying the Chip Maker

The second gear manufacturer is the matchless that makes the chip that powers the arranger. The chip is what controls the behavior of the card, which is why it ‘s much more important to determine the chipset manufacturer than the adapter manufacturer. For model, Panda Wireless cards frequently use Ralink chipsets, which is the more critical piece of information to have .

Determining the Chipset

Certain chipsets are known to work without much or any shape needed for getting started, meaning that you can expect an adapter containing a especial supported chipset to be an easy choice. A good place to start when looking up the chipset of a radio network adapter you ‘re considering buy is Aircrack-ng ‘s compatibility pages. The older “ deprecated ” version still contains a fortune of utilitarian information about the chipsets that will work with Aircrack-ng and other Wi-Fi hack tools. The newer translation of the Aircrack-ng scout is besides useful for explaining the way to check newer cards for compatibility, although it lacks an easy-to-understand table for compatibility the room the deprecate page does. digression from Aircrack-ng ‘s web site, you can often look up menu details on a resource like the WikiDevi database, which allows you to look up details on most radio network adapters. Another resource is the number of officially supported Linux drivers, which includes a handy mesa showing which models back monitor mode. Atheros chipsets are particularly popular, thus if you suspect your device contains an Atheros chipset, you can check an Atheros-only guide. Having a hard prison term finding the chipset of a card you ‘re looking for ? You can find a visualize of the FCC ID number on the dagger of the device. The number can be input into websites like which include home photos of the chipsets in consumption. once you ‘ve determined the chipset of the device you ‘re considering, you should be able to predict its behavior. If the chipset of the wireless network adapter you ‘re considering is listed as supporting monitor mood, you should be estimable to go .

Other Considerations in Adapter Selection

aside from the chipset, another consideration is the frequency on which the adapter operates. While most Wi-Fi devices, including IoT devices, function on the older 2.4 GHz band, many newer devices besides offer 5 GHz networks. These networks are by and large faster and can transfer more data, but are besides normally paired with a 2.4 GHz network. The wonder when buying then becomes, is it worth it to invest the excess money in a 2.4/5 GHz antenna that can detect ( and attack ) both ? In many cases, unless the point of your attack is to probe all of the available networks in an area, a 2.4 GHz menu will be all right. If 5 GHz is important to you, there are many 5 GHz Wi-Fi cards that support monitor manner and mailboat injection, an case being the Panda Wireless Pau09 .

Another significant factor is determining whether you need to mount a specify antenna. While most omnidirectional antenna will be very well for a novice, you may want to switch to an antenna with a directional model to focus on a particular net or area quite than everything in a circle around you. If this is the case, look for adapters with antennas that can be removed and swapped with a unlike type .

Option 2: Test Your Existing Wireless Network Adapter

If you already have a radio network adapter, you can check pretty well if the chipset inside supports monitor mode and package injection. To start, plug in the network arranger and then open a terminal windowpane. You should be able to determine the chipset of the network arranger by plainly typing lsusb -vv into the terminal window and looking for an output like to below.

lsusb -vv

  iSerial                 3 (error)
  bNumConfigurations      1

In my exercise, I ‘m looking at a Panda Wireless PAU06 network arranger, which reports having an RT5372 chipset from Ralink, which is listed as supported ! once you know the chipset of your calling card, you should have a boisterous estimate of what it can do .

Testing Your Adapter’s Abilities

now, let ‘s move on to more active quiz of the adapter ‘s capabilities .

Step 1: Put Your Card in Monitor Mode

For this gradation, we ‘ll break out Airmon-ng, but before that, you ‘ll need to locate the name of the interface. On your system, run the command ifconfig ( or ip a ) to see a tilt of all devices connected. On Kali Linux, your batting order should be listed as something like wlan0 or wlan1.


eth0: flags=4163  mtu 1500
        inet  netmask  broadcast
        inet6 fe80::a00:27ff:fe59:1b51  prefixlen 64  scopeid 0x20
        ether 86:09:15:d2:9e:96  txqueuelen 1000  (Ethernet)
        RX packets 700  bytes 925050 (903.3 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 519  bytes 33297 (32.5 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73  mtu 65536
        inet  netmask
        inet6 ::1  prefixlen 128  scopeid 0x10
        loop  txqueuelen 1000  (Local Loopback)
        RX packets 20  bytes 1116 (1.0 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 20  bytes 1116 (1.0 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

wlan0: flags=4163  mtu 1500
        ether EE-A5-3C-37-34-4A  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

once you have the name of the network interface, you can attempt to put it into monitor mode by typing airmon-ng start wlan0 ( assuming your interface name is wlan0 ). If you see the output below, then your tease appears to support radio receiver monitor mode.

airmon-ng start wlan0

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 run 'airmon-ng check kill'

  PID Name

  522 dhclient
  718 wpa_supplicant

PHY	Interface	Driver		Chipset

phy1	wlan0		rt2800usb	Ralink Technology, Corp. RT5372

		(mac80211 monitor mode vif enabled for [phy1]wlan0 on [phy1]wlan0mon)
		(mac80211 station mode vif disabled for [phy1]wlan0)

You can confirm the results by typing iwconfig, and you should see the name of your card has changed to add a “ monday ” at the end of your batting order ‘s appoint. It should besides report “ Mode : admonisher ” if it has been successfully put into monitor manner.


wlan0mon  IEEE 802.11  Mode:Monitor  Frequency:2.457 GHz  Tx-Power=20 dBm
          Retry short  long limit:2   RTS thr:off   Fragment thr:off
          Power Management:off

Step 2: Test Your Card for Packet Injection

Testing for mailboat injection is reasonably aboveboard to test thanks to tools included in Airplay-ng. After putting your wag into monitor mood in the end step, you can run a screen to see if the wireless network arranger is capable of injecting packets into nearby radio receiver networks. Starting with your interface in monitor mode, make certain you are in proximity to a few Wi-Fi networks so that the adapter has a gamble of succeeding. then, in a terminal windowpane, type aireplay-ng –test wlan0mon to start the packet injection test .

If you get a leave like above, then congratulations, your network menu is successfully inject packets into nearby networks. If you get a result like the one below, then your card may not support mailboat injection.

aireplay-ng --test wlan0mon

Step 3: Test with an Attack to Make Sure Everything Works

finally, we can put the above two steps into drill by attempting to capture a WPA handshake using Besside-ng, a versatile and highly utilitarian creature for WPA snap, which besides happens to be a great manner of testing if your batting order is able to attack a WPA network .

  • Don’t Miss: Automating Wi-Fi Hacking with Besside-ng

To start, make sure you have a network nearby you have permission to attack. By default, Besside-ng will attack everything in range, and the attack is identical noisy. Besside-ng is designed to scan for networks with a device connected, then attack the connection by injecting deauthentication packets, causing the device to momentarily disconnect. When it reconnects, a hacker can use the information exchanged by the devices to attempt to brute-force the password. Type the besside-ng -R ‘Target Network’ wlan0mon command, with the -R field replaced with the name of your trial network. It will begin attempting to grab a handshake from the victim network. For this to work, there must be a device connected to the Wi-Fi network you ‘re attacking. If there is n’t a device introduce, then there is no one to kick off the network therefore you ca n’t try to capture the handshake.

besside-ng -R 'Target Network' wlan0mon

A Flexible Network Adapter Is Key to Wi-Fi Hacking

A knock-down radio network arranger with the ability to inject packets and listen in on Wi-Fi conversations around it gives any hacker an advantage over the airwaves. It can be confusing picking the right arranger for you, but by carefully checking the chipset contained, you can ensure you wo n’t be surprised when you make your purchase. If you already have an adapter, putting it through its paces before using it in the field is recommended before you rely on it for anything besides crucial.

I hope you enjoyed this guide to testing your radio network cards for package injection and wireless monitor mode. If you have any questions about this tutorial on Kali-compatible radio network adapters or you have a remark, feel free to reach me on Twitter @ KodyKinzie .
