<DIV><FONT size=2>At the moment there are no current plans to support native
WiFi in WinPcap, although I've definitely been thinking about it. The main
problem in supporting it is that it's not trivial, it basically requires to
rewrite all the kernel module of WinPcap in order to be an NDIS6 filter driver
(and as consequence, a lot of the installation code). I've actually experimented
with it and read some documentation, with this output:</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>- not all the wireless cards support the native wifi monitor
mode. vista supports both the "legacy" wireless drivers (i.e. the ones that also
work on 2000/XP) as well as native WiFi drivers. Only the latter ones *can*
support monitor mode. </FONT></DIV>
<DIV><FONT size=2>- even when they support monitor mode, I've seen native wifi
drivers that do not provide the original wireless frames. If you are only
interested in the L3 information, that's ok. But if you are interested in the
strictly wireless related information (e.g. 802.11 control/management frames),
that could be a problem. For example, I've seen 802.11n native WiFi drivers that
strip all the 802.11N related information from the frames.</FONT></DIV>
<DIV><FONT size=2>- transmitting on adapters in monitor mode should
be possible, but not documented (and probably not supported by
MS).</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Hope this clarifies the situation.</FONT></DIV>

mode support for 802.11</DIV>
<DIV><BR></DIV>
<DIV>Hi,</DIV>
<DIV>I'm wondering whether winpcap plans to or already support the native WiFi
monitor mode on Vista. If so what's the status, and if not what's the
difficulty there?</DIV>
<DIV> </DIV>
<DIV>Many thanks,</DIV>
