Engineers also do not have to run separate Tshark instances to capture each Wi-Fi channel and subsequently merge the files together since AirPcap software includes a virtual channel aggregator that can be selected for capture within a single Wireshark instance. The benefit of this approach is easier capturing because many engineers are unfamiliar with Linux. This can be tedious and more time-consuming for everyday use. The capture files must then be merged together, typically using the Mergecap tool included with Wireshark. However, when multiple simultaneous captures are required, separate instances of Wireshark (or Tshark, the command-line version) must be run. Many Wi-Fi and Security engineers use the Backtrack distribution coupled with a compatible wireless card.

Use a Linux Distribution with custom Wi-Fi drivers.

For this reason, engineers typically take one of two approaches to capture Wi-Fi traffic with Wireshark: Unfortunately, Microsoft Windows is very limited with regard to monitor mode support. This usually requires the Wi-Fi adapter to be disconnected from the network. You will want to make sure that the adapter you use supports capturing in ' Monitor Mode' not 'Promiscuous' mode. This is because differences exist between operating system platforms which may prevent the ability to capture all wireless frames over the air.

The selection of a supported wireless adapter model for use with Wireshark can be tricky. It is worth your time to read (even almost 4 years later. So remember, never use channel scanning for protocol analysis!ĭevin Akin originally covered multi-adapter Wi-Fi captures in his CWNP whitepaper titled The Triple Blendy. If you are scanning 3 channels, then you can only capture 1/3rd of the frames (actually less due to hop time between channels). Remember, scanning ALWAYS results in missing frames. And if the scanning duration is set to a large a value then there is a good chance the adapter will be on the wrong channel when the roam occurs, as well as the inability to calculate roam times between data packets on the 'old' and 'new' AP as discussed in part 3 of this series. If the scanning duration (also called dwell time) is set to a small value then the adapter will likely miss frames related to the roaming and authentication exchange because it hops away to a different channel before the roam completes. Scanning between channels with a single adapter is not sufficient because the adapter will miss frames transmitted on alternate channels. Be sure to check the supported adapters list for the protocol analyzer software that you intend on using to capture and analyze the traffic. I have had good success with the Rosewill RHB-330 USB hub. In order to perform wireless roaming analysis, you will need multiple wireless adapters to capture frames simultaneously on different channels. The hardware required typically includes 3 wireless adapters and a USB hub.

You can download and open this packet capture if you want to follow along. Throughout this blog post and the next, I will be using actual roaming events that I captured with my iPhone as an example. Take more active control to ensure network performance matches desired service levels.Implement changes to infrastructure and client devices to optimize performance.Identify opportunities to improve and optimize performance.Analyze gaps between current network performance and application requirements.Baseline current client roaming performance.Remember from part 1 that roaming analysis provides insight into how decisions made on wireless architecture, network design, client selection, and configuration impact overall network performance. Performing Wi-Fi roaming analysis will enable network architects and engineers to: In this post, we'll take the concepts we've learned in the first three articles and apply them in a live environment by performing a wireless packet capture and analyzing the roaming performance of an actual client device. This article is part 4 in the Wi-Fi roaming analysis series.
