Uhm... stupid question: are you sure you are choosing the right adapter with
pcap_open (in your l_Device variable)?
Have you tried to use of the samples of WinPcap and see if they work?
Have a nice day

I already change to pcap_open_live and the problem is the same, is
so strange, my program works perfect, the problem persist only when computer
has two active adapters, and second adapter receive a mirror.
Thanx be the same
