        Yes

        2- Is the paquets captured by winpkfilter ara the original paquets or

        Not sure what you really mean here, but if you modify the packet which is sent/received over WiFi it will come modified to network/MSTCP. This is unlike winpcap which gives you a copy of the packet and its modification won’t change anything.

          Many thanks for your help, but i have more questions please.

          first, i explain my project : i have to capture wifi paquets from a wireless network adapter, modify (crypt data) this paquets with my application, and sending modified paquets to the wireless network adapter.

          the problem is that all codes are about TCP, UDP,IP… , no one about wifi, so please can you help me about capturing/sending wifi paquets?

          Thanks in advance
          Regards

            Packets [received from]/[sent to] WiFi network interface are normal Ethernet 802.3 frames (WiFi NIC driver strips 802.11 specific headers). So basically at the NDIS level WiFi network interface does not differ from normal LAN interface and packets can be processed at the same way.
