CaptureSetup/WLAN – The Wireshark Wiki

If you are capturing traffic to troubleshoot a wireless connectivity problem, or to analyze traffic for a single AP or station, it’s best to capture on a single, fixed channel. I did that but I think my NIC can’t capture packets in monitor mode, so instead of getting an AirPcap adapter, I was thinking to go for a cheaper option such as this: The next section describes the operating systems supported and limitations by chipset.

Because the new kernel wifi architecture allows multiple virtual interfaces vif to share of physical interface wiphy it is essential to ensure aorpcap any other vif’s sharing a wiphy with your monitor vif do not retune the radio to a different channel or initiate a scan. I saw some people who also have the Driver Broadcom There are many, many manufacturers beyond the examples give here.

The golden rule is if the radio is not tuned to the channel you will miss stuff! Knowing the wireless chipset manufacturer allows you to determine which operating systems are supported, software drivers you need and what limitations are associated with them.

WLAN (IEEE 802.11) capture setup

In this mode, the driver broadom put the adapter in a mode where it will supply to the host packets from all service sets. Channel hopping will inevitably cause you to lose traffic in your packet capture, since a wireless card in monitor mode can only capture on a single channel at any given time. Sometimes the name of the files.

The box on the right contain all the information needed to identify the chipset manufacturer and model. In Wireshark, if the “Monitor mode” checkbox is not grayed out, check that check box to capture in monitor mode.

At this time April there is no way to read monitor flags back out the kernel. Optionally, you can specify additional channels with a different dwell time for each channel. Promiscuous mode is, in theory, possible on many You might have to perform operating-system-dependent and adapter-type-dependent operations to enable monitor mode, described below in the “Turning on monitor mode” section.

If this happens you will silently miss packets! Without any interaction, capturing on WLAN’s may capture only user data packets with “fake” Ethernet headers.

In Linux distributions, for some or all network adapters that support monitor mode, with libpcap 1.

You may have to perform operating-system-dependent and adapter-type-dependent operations to enable monitor mode; information on how to do so is given below. If that checkbox is not displayed, or if the -I command-line option isn’t supported, you will have to put the interface into monitor mode yourself, if that’s possible.

Here is an example of my interfaces file. airocap

The exact same principles apply to internal devices, the brosdcom difference is they will be found under lspci. For example, if you wish to channel hop between the IEEE Please read and understand the following prior to using this page: Wireshark does not have a built-in facility to perform channel hopping during a packet capture, but you can have multiple processes controlling a single wireless card simultaneously; one to perform the channel hopping, and a second process to capture the traffic Wireshark, in this case.

How much peer support and documentation is available for the card and software drivers. You can use the undocumented “airport” command to disassociate from a network, if necessary, and set the channel.

If it is not an
