Questions
about if a certain Wifi adapter is compatible with the Aircrack-ng suite or
what Wifi card is capable of packet injection and operating monitoring
mode are commonly asked at discussion boards and social
media. A Wifi adapter that is capable of packet injection and
monitoring mode is trivial and important functionality to be successful in
Wifi hacking. Wireless packet injection is spoofing packets on a network to
appear as if they are part of the regular network communication stream. Packet injection
allows to intercept, disrupt and manipulate network communication. An
example of this is sending a deauthentication message from an
unknown party outside the network to a connected client as if it was
send by the wireless router. This will result in the client disconnecting from
the router. Monitoring mode is one of the six modes a Wifi card can operate in
which allows you to capture network packets without having to associate with
the access point.
If you are looking to buy a
Wifi card which is capable of packet injection using the Aircrack-NG suite you
can have a look at the following list with supported Wifi adapters:
Steps To Perform An Injection Test :
First we
need to put the Wifi adapter in Monitoring mode using the following command:
airmon-ng start wlan0
If necessary kill the processes Kali is
complaining about:
Testing
if your Wifi adapter support packet injection can be done using the
following command:
aireplay-ng –test wlan0mon
Packet Injection is working for this
card!
In Kali Linux ‘iwconfig’ will show you
the operating mode of your Wifi card:
