Dear all, According to this document from wireshark http://wiki.wireshark.org/CaptureSetup/WLAN#Promiscuous_mode some wireless cards support promiscuous mode to capture the packets belonging to the same WLAN, but not destined to one of its local interface. I tried with TP-LINK TL-WN722N 802.11n USB dongle, on Ubuntu with ath9k_htc driver. I make the USB card associated to an AP (without encryption), and sniff with wireshark. Meanwhile I have another laptop sending ping traffic through the same AP, but the USB dongle never overheard any traffic from this laptop. Occasionally, the USB dongle could only overhear some downlink traffic, which is sent from AP to the laptop. Could anyone confirm the current support of promiscuous mode on ath9k_htc? Thanks a lot in advance! jintao -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
