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.
