![]() ![]() It may be possible to do the same exporting the capture via Windows Network Monitor (.cap file) and opening in Wireshark. ![]() I was able to display 802.11 frames in Wireshark for the first time - capturing with netsh trace start capture=yes and converting the trace file to pcapng format with etl2pcapng. I tried investigating if there is a way to set the interface to monitor mode (which is what is this scanning option button is used for, ultimately) via netmon's command line counterpart - nmcap - to no avail. In a short, when configuring the properties of my wireless NIC in Windows Network Manager I need to see a screen like And so am I, at least following this assumption on how do I know whether my process is running with administrator privileges. Now, the article mentions one must be running netmon with Administrator privileges. Whatever) - because it shows the 802.11 frames as regular ethernet ones - so one cannot even find frame controls in the captured traffic, making it way more difficult for novices to start grasping what are they looking at (I have started from scratch with Wikipedia articles).īack to the article and to my problem - with netmon things seem to start making sense, but to my exacerbating frustration - when it comes to finally instruct on how to configure netmon to capture all frames including managament ones - it says one needs to apply some settings in the scanning option button. To my disappointment (and to all the other novices trying to do the same, I guess) - Wireshark, which was my first option up to several days ago - does a poorer job (the article says it's not wireshark's fault, but windows. Running netmon and starting a capture on your wireless NIC will indeed show frames with types 10 (2) (apply following filter: = 2), but no management ( = 0). As I mentioned at the top, I am after beacon frames, which consist of a specific sub-type of management frames. Having spent hours browsing through many articles, I found this gem - which seems to wrap it all up.Īs explained by the article - wireless interfaces, by default, do not allow capturing of EVERYTHING that is exchanged in the network - usually the only type of network frame the capturing utilities will catch are data frames. My wireless NIC is Intel Wifi AX201 160mhz, which seems to support monitor mode. I am trying to capture network traffic - specifically management frames (and from these, particularly beacon frames) in Windows. ![]()
