after reading the wireless capture setup, I think the problem is that I'm running Wireshark on Windows XP and this apparently doesn't work well when sniffing other machine's traffic in a wireless network environment.
Has anyone found a way to do this?
Sometimes, an extra word or two can greatly enhance the focus of a given
question:
"Has anyone found a FREE/trivially-inexpensive way to do this?"
The challenge of clarifying "this" might pose a greater challenge:
If "this" refers to setting the wireless adapter transmitting &
receiving the packets in question as the capture interface while running
wireshark atop M$ windows operating systems, then the limitations
referred to below apply. Otherwise, hardware-based solutions still
appear to work (in this case, it would be somewhat inexcusable if they
didn't):

The only programs I know that can do Wi-Fi captures on Windows XP, such as Tamosoft's CommView for WiFi:

or WildPackets' OmniPeek:

do so by providing their own device drivers for a set of supported 802.11 adapters. Even Microsoft's own Network Monitor 3:

only supports Wi-Fi capturing on Windows Vista and Vista 7; they rely on some networking features that first showed up in Vista (NDIS 6 and Native Wi-Fi) and, I think, rely on the driver for the Wi-Fi adapter to support Native Wi-Fi). Wireshark uses WinPcap on Windows; WinPcap doesn't use the Vista-and-later networking features and thus doesn't support monitor mode on Wi-Fi.
