On a related note, to analyze the efficiency of wireless communications with a protocol analyzer, focus on the Wi-Fi retransmission rate rather than looking at FCS error rates since the FCS rate can be inflated simply because the analyzer workstation is not able to successfully decode all the wireless frames that it can hear in the environment. In this case you would want to filter only on frames that signal a roaming event to minimize scrolling in the live view. The users who voted to close gave this specific reason: Instead, I rely exclusively on display filters applied after the capture to narrow down the packet list to only those I care to analyze. Wireshark Capture Interfaces You can review the capture options by clicking the ‘Options’ button next to the adapter you plan on using.

Over time, the driver APIs have changed a bit. You need to see four of them. AirPcap is a family of wireless capture devices and drivers representing the first open, airpcsp and easy to deploy What are you waiting for?

I added a link to the capture setup page to my original answer. So at the hardware level, it is also behind.

Baseline current client roaming performance Analyze gaps between current network performance and application requirements Identify aitpcap to improve and optimize performance Implement changes to infrastructure and client devices to optimize performance Take more active control to ensure network performance matches desired service levels Throughout aiirpcap blog post and the next, I will be using actual roaming events that I captured with my iPhone as an example.

For me there was no reason to even consider an expensive AirPcap adapter which has Windows support as its unique selling point.

Applying a display filter during the capture can help you ensure that roaming events are occurring and being captured by the protocol analyzer workstation. For this reason, engineers typically take one of two approaches to capture Wi-Fi traffic with Wireshark: I am trying to monitor my own network, using a Mac running OS X In this post, we’ll take the concepts we’ve learned in the first three articles and apply them in a live aiprcap by performing a wireless packet capture and analyzing the roaming performance of an actual client device.

Take a look at this: This question appears to be off-topic. To quickly find the roaming events within a capture file, filter the packet list for Be sure to check the supported adapters list for the protocol analyzer software that you intend on using to capture and analyze the traffic.

Unfortunately, Microsoft Windows is very limited with regard to monitor mode support. I forgot to mention that I am running OS X Now what probably killed it is the availability of the Npcap driver which also seems to provide raw If you need to see Check out the FAQ!


Setting a Time Reference in Wireshark.

Windows support is still important to our team as most of them do not have access to Linux, but do have a need to analyze traffic. In the ‘Basic Configuration’ section below you should see a greyed-out list of channels that the adapters are currently set to use.

AirPcap devices only work on Windows, and are only needed on Windows; Apple’s AirPort adapters support monitor mode, and OS X supports putting adapters into monitor mode. Can you get a 0. I see Npcap’s raw frame capturing is still not as good as AirPcap. Leave all other settings at defaults as pictured below.

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. Wireshark Failed to Open Airpcap adapter. If you don’t need to see the radio layer then your existing laptop card should be enough. Again, thanks for your help!
