That being said, I have tried that without any noticeable difference. I use both wireshark and tcpdump for my testing. I'm just looking for wireless packets that one normally sees when doing wireless sniffing (there is a lot of sta's / AP's around me) acks, CTS/RTS, various management frames, etc. The missing traffic is pretty obvious when comparing to another working wifi stick (in my case 9khtc). I guess if this is not an obvious problem, I can go bisect until I find where the problem was introduced. This was working fine in the past. Example: carl9170 It seem like all the traffic I see is from AP's, no STA. The three types are all I ever see (1 data frame, and two mgmt frames, no ctrl). ... -82dB signal antenna 5 Beacon (...)
