Wireshark can only do what the network adapter it's using, and the OS
packet capture mechanism and network adapter driver, allow it to do.

AirPcap is hardware, not just software.
It works around an underlying problem with Windows, namely that the
networking mechanisms in Windows prior to Windows Vista don't do a very
good job of supporting packet capture on 802.11 devices.
If you're running Windows prior to Vista, the chances are unfortunately
very good that the driver doesn't support promiscuous mode, which means
that you won't be able to run in promiscuous mode while associated with
the access point's network, and the chances are *certain* that the
driver doesn't support monitor mode.
If you're running Vista, Microsoft Network Monitor:

can capture in monitor mode if the driver for the wireless network
adapter supports it. I don't know which drivers support it.
If you're not running Windows at all, you might have better luck; the
drivers do a better job of supporting promiscuous mode, and man of them
support monitor mode, as per
