1- can winpkfilter supporte WIFI paquets ?.
Yes
2- Is the paquets captured by winpkfilter ara the original paquets or
just a copy of original? .
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.
