  Dear development team:

  I am a user of winpcap, now I install winpcap4.0 in Vista Ultimate.

  I use wireless adapter:  DWA-110 USB Adapter.

  the wireless adapter driver version: NDIS6.0

  I download winpcap4.0 Developer's pack and I rebuild the iflist project with VC++ 6.0.(No error, No warnning).

  I use NDIS6.0 driver for this wireless adapter.

  I exeute iflist.exe. It's appear a error -->  the description of this adapter is catch Error, but the instanceID is OK.

  The Adapter's description will show "microsoft".(It's wrong)

  When I use NDIS5.x Driver for this adapter, the iflist.exe work properly.

  Is the packet.dll not for NDIS6.0 driver??

Packet.dll is not involved in the NDIS stuff, it's just a user level DLL that communicates with npf.sys, which is an NDIS 5.x protocol driver. There shouldn't be any problem with an NDIS 5.x protocol driver on top of a NDIS 6.0 miniport (NDIS should provide the proper thunking to convert between 5.x and 6.0) but it doesn't seem so. 

I have a wireless card that should have an NDIS 6.0 miniport (not the dlink usb one, it's a dlink cardbus one with atheros chipset), i'll try to see if I can replicate a similar problem with what I have. In the meantime, can you try using the tracing version of packet.dll available at http://www.winpcap.org/bugs.htm and send me the generated winpcap_debug.txt file? Thanks!

Have a nice day
