Maybe a TcpWindowSize issue on Windows XP? By default, this is higher for a 100Mb/s interface than the wireless interface. FWIW, I get the full speed of my Internet connection over a ral AP, 6Mb/s, and, when using it normally, with WEP I still can get about ~20Mb/s. Have you tried shutting off the power saving features of the Intel Wi-Fi?
