I have searched the forums, and found one guy with the same issue but no resolve. So, I will try this now.

I am creating a real-time network visualization app using libpcap. My previous use with libpcap made it seem like this would be cake. However, I'm running into problems seeing other's network traffic. I have a TP-LINK WN722N card (Atheros), and am running on linux (obviously).

The scenario is, that I have my host computer S (doing the sniffing), and two user computers A and B. I want S to be able to sniff the traffic flow between A and B. Currently, I can capture 802.11 frames using wireshark on the network. I have entered the decryption key, but I never seem to get any HTTP (or ICMP) traffic flow coming through from A or B. I'm wondering why I can only see traffic intended for broadcast or intended for my computer. Monitor mode AND promiscuous mode are enabled.

Thanks for your help!

I will note that unsecured networks have 0 problem capturing all data.
