(Under Ubuntu 14.04) To: linux-wireless@vger.kernel.org Content-Type: text/plain; charset=UTF-8 Sender: linux-wireless-owner@vger.kernel.org List-ID: Hi, All: I configured the Wifi Monitor mode with Intel 7260 card under Ubuntu14.04 and then used Wireshark to capture packets from air. But I could only get management/control packets but no data packets. I tried different channels and also with HT20 or HT40+/-. The commands I used were: iw dev wlan0 interface add mon0 type monitor iw dev wlan0 del //I googled and was told I needed to delete the wlan0 first. Or else I got device busy (-16) error ifconfig mon0 up iw dev mon0 set channel 1 I also tried to use other ways like "airmon-ng start wlan0". All the observations were same, no data packets. It's weird! Anyone has a clue? Thanks! dlw
