Hello everyone, I'm trying to sniff my network to detect on-going connections and I get the following problem:

First of all my equipment is ALFA network AWUS036H adapter and BT5R2 Gnome.

I'm sniffing in monitor mode (mon0) and I can see only 802.11 management, control and data multicast or broadcast packets,
but no actual data, which I know is passing since I'm pinging the router constantly with another computer in my network.
I tried removing the encryption and still can't see the pings in wireshark or airodump-ng.

To be clear, I can inject packets and see some packets in monitor mode, which are not actual data...
Also, distance is not the issue since both computers and the router are in the same room.

I'll appreciate your advice =]
