[Winpcap-users] Vista Wireless Architecture

[Mani, Swetha (Cognizant)]

HI !!!

I came across your messahe in the winpcap users group. You have
mentioned that WinPcap3.1 and 4.0 will have problems on listing the
adapter names on a Vista Beta 2 machine. Can you please tell me what are
the problems specifically ? I have tried the following but to no avail.
Still the wireless adapter is not getting listed.

1.    installed WinPCap 4.0 - npf.sys, packet.dll and wpcap.dll get
deputed to System32 folder.
2.    complied the source code for packet.dll and wpcap.dll. Here the
DDk was not used to install the driver. Then replaced the existing
packet.dll and wpcap.dll with the new one.
3.    I also checked in http://www.micro-logix.com/WinPcap/Supported.asp
for the list of supported wireless adapter and the one I am using (
Intel Pro / Wireless 2200BG Network Connection )
I cant figure out what might be the problem.

Thanks and regards
Swetha

  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 Vista with WinPcap3.x or 4.x will overcome this previous
limitation.

  Or put another way, I have not read anything on your site specifically
supporting Vista 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.

  

Kenneth,



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?).

In any case we are definitely interesting in evaluating native wifi and
exploit it to better support wifi networks.



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.



Have a nice day

  Kind regards,
