[Winpcap-users] packet sending on win7

[Gianluca Varenni]

Can you please try connecting the two computers directly with an ethernet cable and see what happens?

Have a nice day

I can not send packets from win7, it has 2 network interfaces, ethernet with direct connection to adsl modem, and wifi connection to notebook.
The packets i send from win7 are visible in wireshark, but actually they do not transmiting over network. both devices (modem and notebook do not receive them).

  Are you saying that the issue happens when transmitting from either a wired host (with an ethernet connection) or a wireless card?

  Have a nice day

  One host directly through the cable, and the second via WIFI.
