There is no way to know that. Basically, if such request fails, you know that promiscuous mode is not supported. If the request succeeds, the miniport is *supposed* to support promiscuous mode.

What is the exact traffic that you capture when you go into promiscuous mode with your card? Which packets are missing? Please consider that in the best case you will be able to see the packets sent on the specific channel your wireless network card is currently using (i.e. the channel used by the AP you are associated to). If for example your network card is not associated to any AP, I don't have a clear idea what you will be able to capture in promiscuous mode, as the card is probably hopping among channel to do network scanning, or even in low power mode.

Have a nice day

        HI
        Thanks for reply. Can you please tell me a way to check either my device card driver is supporting promiscuous mode

          The card (i.e. the hardware) supports promiscuous mode, but probably the driver (provided by the card manufacturer) doesn't. WinPcap just sends a request to the NIC driver to enable promiscuous mode. It's entirely possible that the NIC driver returns success, but fails to deliver all the packets anyway.

                    Most of the wireless network cards do not support promiscuous mode, i.e. even when they accept the request to go into promiscuous mode, they will just capture to/from the machine.

                    Also, your problem seem to be related to fedora 7, this mailing list is mainly related to the windows port of libpcap. For more detailed answers, I would suggest you to send your questions to the tcpdump-workers mailing list.

                            HI
                            Thanks for reply. I have solved the previous problem by adding static MAC Address in arp talble. now the problem is that my wifi card in not capturing packets in promiscusous mode my wifi card is DWLG122(D link) and it support promiscuous mode when i see the log the card goes into promiscuous mode but it is not capturing packets that are not destined to it. Any help in this regard i have open the card using pcap_open_live(). I am using fedora 7
