Talked to Dell and they said that with Windows XP they have a problem with their Proprietary WLAN Management Software. I disabled it by opening it from the system tray and then unchecked the box that says "Let this tool manage your wireless networks" and then also unchecked the box that says "Show utility icon." Left the "Enable Radio" box checked.
