Hi Gianluca,

I successfully compiled the npf driver and the packet library. I wrote a small application to list down the adapters present. I am facing an issue here where in I observed that only Atheros based card are not getting listed. Is this a known issue? Is there is a solution to this problem?


1. Vista Business/Ultimate SP1
2. Winpcap 4.1.beta

I am able to list all micosoft and broadcom based cards. Please help me to get some resolution to above matter.

Thanks a lot Gianluca  I will surely have a look at wcap.dll code.

  Hi All,

I want my application talk to driver and receive the 
  packets captured  from air. And for the same I need protocol driver to 
  talk pull the packets from the driver and put them to user buffer. I have 4.1 
  wpcap source.

I have few questions. It would be great if some one can 
  help me with them:

1. Compilation environment for npf (protocol driver) 
  and packet library.
Please follow the directions in the WinPcap 
developer's pack, or online at

2. Will I have to do any changes in packet library to make it work 
  for my driver to push the packets up the application?
Integrating support for a new "driver" can be 
tricky. I suggest you to integrate it at the wpcap.dll level, it's much easier 
than integrating it into packet.dll. If you modify wpcap.dll, I suggest you to 
download the sources for 4.1beta5 and have a look at how I added support for the 
TurboCap cards in the files pcap-tc.h and pcap-tc.c

3. Are there any odds that needs to be taken care in Vista? I am new 
  to this part of windows.


Your help is greatly appreciated 
Have a nice day
