wireless captures</DIV>
<DIV><FONT size=2></FONT><BR></DIV>
<DIV>Hi Gianluca,<BR><BR>Thanks for the help.i have used SureCom wireless card
to capture the data and i am using the same for the replaying.but i am not
getting why wireless card is converting it as ethernet
packets?<BR></DIV></BLOCKQUOTE>
<DIV><FONT size=2>The standard windows driver for a wireless card does that.
This is how wireless drivers work on Windows pre-Vista. And WinPcap captures
what the wireless driver passes to it.</FONT></DIV>

<DIV>a friend told me that windows doesn't understand the wireless
packets and the device driver internally convert all the wireless packets in
to ethernet format and forward them to the upper layer.is it so?</DIV>
<DIV> </DIV></BLOCKQUOTE>
<DIV><FONT size=2>Exactly. Or better, for ease of protocol development Microsoft
decided that the wireless drivers had to export fake ethernet packets and manage
all the control/management frames internally. This behavior changed in vista,
and now vista wireless drivers can export native wireless
frames.</FONT></DIV><FONT size=2></FONT>
