Uses or libraries to capture network traffic on Windows. Winpcap libraries are not intended to work with wireless network cards, therefore they do not support WiFi network traffic capturing using Wireshark on Windows. Therefore, Wireshark monitor mode for Windows is not supported by default.

Winpcap Capture Limitations and WiFi traffic on WiresharkCapture is mostly limited by Winpcap and not by Wireshark. However, Wireshark includes support, a special -and expensive- set of WiFi network adapters, which drivers support network traffic monitoring on monitor mode. In other words, WiFi network traffic capturing on.products include an NDIS traffic capture driver that captures WiFi network traffic on monitor mode on Windows, capturing WiFi traffic with Wireshark on Windows 10, Vista, Windows 7, Windows 8, and Windows 8.1.
This driver adds wireless network compatibility on Windows to other WiFi sniffers. NDIS Driver and WiFi interfaces on WiresharkTo make this integration possible, Acrylic installs an airpcap.dll library in the system. When Wireshark loads the installed airpcap library, it returns a fake list of airpcap network cards installed. One Airpcap device for each integrated WiFi network card or external USB WiFi network card.Through this method, you can use your preferred network analyzer compatible with Airpcap to monitor WiFi packets under windows. You can view wifi traffic by using Wireshark, cain & Abel, Elcomsoft wireless security auditor or with Acrylic. By double clicking on the network interface on wireshark, you can access the interface settings.
You can see that the interface shows a link-layer header, which includes captured packet signal level information.By clicking on the “ Wireless settings” button, you can configure advanced settings, such as WiFi channel to monitor and FCS check. FCS, or, is a WiFi network packet integrity signature that discards corrupt packets. WiFi traffic capturing using WiresharkAll in all, after installing, launch Wireshark with Administrator privileges (by right clicking on the Wireshark icon and selecting “Run as administrator”) and select any NDIS network interface WiFi network card. In this example, the Dell integrated WiFi network card ( Dell Wireless 1702/b/g/n). Video tutorial Acrylic WiFi NDIS driver with Wireshark on Windows. Hello Sancho,With Acrylic WiFi you can see your surrounding networks with all WiFi adapters. Only the special feature ‘Monitor mode’ requires a supported adapter.
However, even if your adapter is not listed as supported it’s possible that the software can inspect WiFi traffic correctly. The adapters listed on our web are a group that we have tested and proved that they work, but are not the only ones that will work.If you can see packets on Acrylic WiFi selecting your adapter in ‘Monitor mode’, then you should be able to see them also in Wireshark. If not, please run Wireshark as administrator.Hope this helps.
Hello Igor,That’s the expected behaviour. While using your WiFi adapter to inspect WiFi traffic the NDIS driver will take complete control of it, so you’re not going to be able to use the WiFi connection during a monitorization. This is necessary in order to set the adapter into a special mode so it can capture WiFi traffic. Besides, as the monitorization performs a channel hopping (i.e. Constantly changing the frequency to receive packets from all channels), it’s not possible to maintain a connection with a WiFi network on a specific channel.Hope this clarifies your question. Nice Post, But I have one question is there any way to handle large amount of PCAP file? I mean I have collected too many data using airodump-ng and i have PCAP file.
But when i was using Wireshark for analysis process it is very difficult to filter interesting part. So I have used PCAP2XML tool for converting my PCAP file into XML or SQlite db and only getting my interested part, like Mac Addresses, Destination Address and all. Have a look also please let me know if some other tools are available.Tool: –Tool Blog: –. Hello,The error is arising while copying 32 bits version of msvcp110.dll (which is a microsoft library). The installer is detecting that the file doesn’t exists and it proceeds to install it. But at the time of copying it to syswow64, the copy function fails because the file already exists, so the installer stops the execution.We suspect that there is some flag on the file that is making the function that checks if it exists to return a false negative. Could you check if that file already exists on c:WINDOWSSYSWOW64?As a workaround, please try to temporarily remove msvcp110.dll and msvcr110.dll from c:windowsSYSWOW64 (please make a backup of those files), and run the installer again.
The installer should correctly copy those files after the installation. Hello Brian,You can check for compatible hardware at. Wireshark timestamps are currently not implemented in our wrapper library, but it’s planned on our TODO.
Next releases will include that option.Regarding b) and c) unfortunately this is not a Wireshark nor Acrylic related issue. The problem relies on the NDIS interface implementation of some manufacturers.
Despite they’re WHQL-certified by Microsoft, many of these NDIS implementations are broken or at least not fully compliant when using monitor mode. That’s the reason why RSSIs are always 0 on your device (some manufacturers have only values of -100, -50 or 0, for instance). Same with FCS. Our driver request NDIS interface to return frames with the specified FCS configuration and is the manufacturer driver responsibility to check if FCS is correct or not. However, some driver implementations do not return those four FCS bytes, or they return garbage instead.We have been trying to contact several vendors but at this time only Broadcom answered us. They state that their drivers are fully NDIS compliant.The solution is to use compatible hardware listed at.
Feel free to report us information about compatibility and other bugs. Hi,This is a great feature!
Being able to use Wireshark in Windows for WiFi capturing has been always been difficult and has required specific wireless interface cards to capture in monitor mode. Your solution means that anyone can now capture WiFi packets, which is great news.I have been testing some captures in Wireshark and it seems to work well.
One question I have is around channel offsets. No matter which wireless NIC I use, the channel offset option is always grayed out.
Will you be building in support for 40Mhz and 80Mhz channels (assuming the NIC can support those channel widths)?ThanksNigel.

Let's start with the theory in order to understand why the process of decrypting Wi-Fi traffic in Wireshark requires some effort and why one cannot just decrypt any captured Wi-Fi traffic even if one has a password from the Access Point.
When transmitting via Wi-Fi, the traffic is encrypted using PTK (the Pairwise transient key). At the same time, PTK is dynamic, that is, it is created anew for each new connection. Thus, it turns out that Wi-Fi traffic for each connection in the same Access Point is encrypted with different PTKs, and even for the same Client after reconnecting PTK changes. To calculate PTK, you need data from a four-way handshake, as well as a password of a Wi-Fi network (in fact, you also need other information, such as the network name (SSID), but obtaining this data is not a problem).
The main thing you need to understand: to decrypt Wi-Fi traffic, you need a four-way handshake. And not any, but exactly the one that happened to transmit the traffic that needs to be decrypted. But to use the captured handshake you need a password of the Wi-Fi network.
So, to decrypt Wi-Fi traffic is needed:
1) a handshake that occurred between the Client and the Access Point immediately prior to the exchange of decrypted information
2) password to connect to the Access Point
Next will be shown two examples of capturing Wi-Fi traffic and its decryption. The first data capture is done using Airodump-ng, and then the wireless traffic will be decrypted in Wireshark. In the second example, the data will be captured and decrypted using only Wireshark.
Capturing Wi-Fi traffic in Airodump-ng
In order for the data to be suitable for decryption, it is necessary that the Wi-Fi card does not switch channels, but capture information on one channel on which the target Access Point operates. Therefore, we start by collecting information about the target access point.
We look at the names of wireless interfaces:
We set the INTERFACE into monitor mode with commands like this:
Run airodump-ng with a command like:
For example, I want to capture and decrypt traffic for the Paangoon_2G Access Point, which operates on channel 9.
Then I need to restart airodump-ng with a command like this:
The WPA handshake string says that a four-way handshake was captured. It means that:
Wi-Fi traffic decryption in Wireshark
Open the capture file in Wireshark. In its original form, the traffic looks like this:
That is, without decryption, we see only the MAC addresses of the data transfer participants, some types of packets, as well as data packets — in which the payload is encrypted.
Before decoding, make sure that there is a handshake, otherwise there is no point in continuing:
![]()
Before decoding, we need to make some changes in the IEEE 802.11 protocol settings.
Go to Edit → Preferences, expand the protocol section and select IEEE 802.11. The settings should be:
When you have the same settings as in the previous screenshot, click on the Edit button next to Decryption Keys (to add a WEP/WPA key):
Click the Create button. In the window that opens, in the Key type field, select wpa-pwd, enter the password for the Wi-Fi network, and after the colon enter the name (SSID) of the network and click OK.
For example, in my case, the password is 00001777, and the network name is Paangoon_2G, then I enter:
Click Apply:
Traffic will be decrypted:
Now there are visible DNS, HTTP requests and responses, as well as other network packets.
If traffic is captured not only for this network, but also for other networks operating on the same channel, or for this network but other clients for which no handshakes are taken, then this traffic will not be decrypted.
Capture Wi-Fi in Wireshark
Wi-Fi traffic can be captured directly in Wireshark. But we first need to switch the Wi-Fi card to the same channel as the target Access Point. This is done by commands like:
In these commands, the words INTERFACE and CHANNEL must be replaced with actual data.
When the interface is switched to the desired channel, in Wireshark, find this interface, in its properties, check the Capture packets in monitor mode box. Then start capturing data:
The subsequent decryption is performed in exactly the same way as shown above.
Conclusion
To decrypt WEP Wi-Fi traffic, you only need to know the password. But APs with WEP almost never occur nowadays.
