Downloaded current driver from chip's website (RaLink) and followed instructions on included CD. Setup successful with their proprietary (non XP) software - which requires a manual step to connect on startup. To autoconnect use the tray icon to configure XP's WiFi Zero Configuration utility. Works fine (but logon screen is now a dialog box instead of full screen logon.) Computer is 30' from access point, thru 2 walls, and gets 2-3 bars.
