Newbie wants to look at other people's packets (promiscuous mode fails to capture packets)

    I want to start looking at other people' packets.
    But I must be doing something wrong.
    Don't I need to be in promiscuous mode to capture "someone elses packets"?

    Following advise read here, I installed netstumbler & wireshark on windows
    in my first attempt to capture encrypted packets from the safety and
    comfort of my home.

    Even though I KNOW there are wireless access points all around me, I can't
    seem to capture anything in promiscuous mode. Please see my netstumbler
    screenshot I just placed at which should be
    pretty normal when it comes to local area access points - so there MUST be
    some traffic that I can capture.

    My question is why doesn't being in promiscuous mode capture any packets
    from my home? When I'm not in promiscuous mode, aren't I only getting my
    own packets (which isn't the point).

    Can you advise me as to what step I'm missing so as to "see" other people's
    packets? It can't be that my neigborhood is that dead, wirelessly, can it?

  2. Yes. It's also known as "monitor mode".
    Yep. If wireshark doesn't see everyone elses packets, you don't have
    a promiscuous mode driver installed. Did you notice AirPcap?
    If you search alt.internet.wireless for "promiscuous mode", you'll
    find some clues on other ways to get it. For example, the WildPackets
    driver will work:
    I like the SSID of "Virus (infected)". Clever. Yeah, any place that
    crowded is going to see some traffic.
    See the WireShark Wiki and FAQ on wireless capture:
    No, I can't. No clue what you're using for hardware. It's a driver
    issue and the various replacement drivers are very hardware specific.
