style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">I understand that capturing 802.11
frames in promiscuous mode in Windows is tricky because of the way Windows
NDIS drivers work and maybe other reasons that go above my head. This
makes using WinPCap+Wireshark frustrating in Windows. However having
read about the complete wireless re-architecture in Vista that includes
“native driver” support (whatever that means, and see link below) I was
wondering if anyone has tested whether <st1:place w:st="on">Vista</st1:place>
with WinPcap3.x or 4.x will overcome this previous
limitation.<o:p></o:p></SPAN></FONT></P>

style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Or put another way, I have not
read anything on your site specifically supporting <st1:place
w:st="on">Vista</st1:place> currently or in the future (only a snippet that
3.1 may work). How about giving us a glimpse of what is in development
or planned for WinPcap to take advantage of these architecture changes, (if
indeed there is any relevance to WinPCap)? Pardon my lack of technical
understanding of drivers.<o:p></o:p></SPAN></FONT></P>

style="FONT-SIZE: 10pt; FONT-FAMILY: Arial"><o:p>native wi-fi support in Vista
will *probably* enable to capture on Wireless LANs without some of the current
limitations. I haven't personally studied too deeply what features will be
available to a protocol driver like WinPcap. What I suspect is that in any case
at the beginning many Wireless card drivers will still expose the old NDIS
miniport interface (ndis 5.1), thus delivering fake 802.3 packets, and will be
only later ported to native wifi (= NDIS 6.0?). </o:p></SPAN></FONT></P>

style="FONT-SIZE: 10pt; FONT-FAMILY: Arial"><o:p>As of now, WinPcap 3.1 and 4.0a
have limited support for Vista. The limitations are mainly related to dialup
support (or better, lack of it) and in the listing of the adapters under some
circumstances (we are working on removing this last limitation). Apart from
that, WinPcap works on vista in the same way as it's working on XP/2000/2003.
