I also note that there is no frame check sequence, nor do 802.11 ACKs show in the stream. Are there any other limitations?
I suspect the radiotap header is never put on the frame prior to sending, though a TZSP header is present:
TZSP: IEEE 802.11: Good
Version: 1
Type: Received packet (0)
Encapsulates: IEEE 802.11 (18)
Signal
Option Tag: Signal (10)
Option Length: 1
Signal: -88
Rate
Option Tag: Rate (12)
Option Length: 1
Rate: 11 Mbit/s (22)
Frame check sequence
Channel
Original Length
End
The FCS value is indicated as 'Good', but there is no numeric value. Are bad frames passed as well? Many dataframes show with rate as Unknown (0), so are these at 802.11n rates? Any way to know the capabilities of what will be sent, or do we have to reverse engineer?
This is all I found in the Wiki documentation:
Packets
Sub-menu: /interface wireless sniffer packet
Sub-menu shows captured packets.
There is some info here
