There is two type of packets in the wifi network traffic, in one the source is one PC and the destination is a wifi router, in the other one the source is the router and the destination is the PC. In my case I have a wifi card in promiscous mode and when I start tpcdump or wireshark I can see the traffic from router to my PC and from the router to all other PC but I can't see the traffic from all other PC to router wifi, why? |

This is probably another case of trying to capture WiFi data with a standard wireless card using a Windows operating system. For this kind of capture you need an Airpcap adapter as sold by Cace Technologies, or use linux instead. Otherwise you won't see the 802.11 layer and data from other stations, just your own. |
