[Winpcap-users] Can't capture 802.11 management frame

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 somebody confirm? I found an email discussion from Gianluca as attached. Is that what you refer to?
I follow your link and track down the following information as in the below link. Is that exactly how Native Wi-Fi supports this?

Presumably you're running on Vista, Windows Server 2008, a Windows 7
beta, or possibly Windows XP with a recent enough service pack, so
that you have the Native 802.11 support:
If so, then, if I remember correctly, the problem is that the WinPcap
driver is an NDIS 5 driver, not an NDIS 6 driver, and doesn't support
the calls required to capture in monitor mode:
