<DIV>HI Guy,<BR><BR>Thank you very much for the tips. We are running on Vista
and Windows 7, so there is always native wi-fi support. It looks like we can
not get management or control frame via winpcap on Vista/Win7. Could you or
</DIV>
<DIV>somebody confirm? I found an email discussion from Gianluca as attached.
Is that what you refer to?<BR></DIV></BLOCKQUOTE>
<DIV><FONT size=2>Yes, you cannot capture management/control frames. Also
consider that even if Vista/Win7 have native wi-fi, the wireless network driver
can still be NDIS5 i.e. not using the native wi-fi support.</FONT></DIV>

<DIV><BR>I follow your link and track down the following information as in the

this?<BR>http://msdn.microsoft.com/en-us/library/aa503317.aspx<BR><BR>Regards,<BR><BR>Wei<BR><BR>-----Original
