My question is rather simple. Can you get a 0.0Mb/s data rate (per stream)?

I have multiple pcap files (165K of packets on average) with 802.11 traffic on them and I always seem to get a few tens of 802.11 data(only) packets showing 0.0Mb/s data rate (in the radiotap header).

As far as I am aware you can only get quantized data rate values (of 1, 2, 5.5, 6, 9, 11, 12, 18, 22, 24, 33, 36, 48, 54)?

The 802.11 traffic was captured with an AirPcap Tx USB adapter and Wireshark Version 1.6.1 (SVN Rev 38096 from /trunk-1.6).

Am I missing something major?

Thanks and regards Alex

As I am still perplexed about this issue I upload an image showing the 802.11 transmission rate vs data (in bits), of an AirPcap Tx/Wireshark measurement.

The figure was produce in Pilot PE, but Wireshark also shows valid data packets (FCS=correct), which are not retransmits, with 0.0Mbps transmission rate.

Any advice would be more than welcome.

Thanks Alex
