Does it require you to buy the Sniffer to get it? I think the suppliers
of commercial network analyzers for Windows write their own drivers for
wireless cards in order to do capture, as the standard drivers, and
NDIS, are extraordinarily unhelpful for capturing. (It would be Truly
Wonderful if Microsoft were to provide a mechanism for doing "raw
802.11" captures in Vista, complete with radio headers. I'm not holding
my breath waiting, however; the document I saw on "Native 802.11", or
whatever they call it, wasn't very encouraging. And even that would
leave pre-Vista systems out.)
Also, does it plug into WinPcap to do capturing? Or do you capture with
Sniffer and then have Wireshark read the captures?
