Gianluca is trying to be nice and get you to "walk before you run". This will let you realize that the issues you may be having are either due to something in winpcap or something in the network stack or something in your code.
If you can successfully talk on a direct wire, then you know something you don't know now. If there is nothing wrong with your code then things should work on a direct wire. Prove that to yourself and to us out here in the peanut gallery. Once that works, you are still faced with two different issues: 1) Talking out the modem. 2) Talking across the Wifi link. Each are different problems with different reasons why they may or may not work. If you take baby steps you'll learn how/why you may be tripping yourself up.

BTW, are you sure it's a DSL modem and not a DSL router?

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). 2010/7/1 Gianluca Varenni <[email protected]> Are you saying that the issue happens when transmitting from either a wired host (with an ethernet connection) or a wireless card?
