Spatial Streams in NetMon 3.4 Capture RRS feed

  • Question

  • Good day! I am using NetMon on Windows 8.1 RTM with the 2978 parser pack. I am able to capture packets in monitor mode, which is GREAT, however, I don't seem to be getting the proper data. For example, on a capture under the heading BasicMCSSet, I see a field called TXMaximumNumberSpatialStreamsSupported. This field should read 3, since this is a 3x3:3 802.11n AP. However, it merely reads 0. I have another AP that I have captured beacons on, and I see the same issue. It too is a 3x3:3 AP.

    Is there something I am missing, or is this a bug? Or perhaps I am missing a parser?


    Thanks for any help!

  • Could be a bug, or some other issue, but I'd probably need a trace to understand it better.  Can you contact me via the blog (http://blogs.technet.com/Netmon) and then we could exchange a trace by email?

    Thanks,

  • Hi Greg,

    Are you using the Netmon API or the UI?

    If you are using the API i would appreciate it if you could post the code that switches the adapter to monitor mode.

    Thanks.
