Could it be the hardware that i use (it is not the Raspberry Pi 3 but instead a fitlet2 -> https://www.compulabnordic.dk/kategori/mini-pc/fitlet2/ and a USB wifi stick supporting 802.11n )

USB Stick:

Please run owl with the -d flag which produces a file failed.pcap in your working directory with all unhandled frames. Post the file here so we can investigate.

[keldnorman]

I could not figure out how to attach the file here so I placed it here instead:

https://www.lostserver.com/static/failed.pcap

Thanks for the code by the way and your willingness to help, I really appreciate the work you did, and I know how much research goes in to this and how much time you spend on it.

I fixed FCS handling, so the frames should now be parsed correctly. Please try out current master.
