When u are on those laptops - does 'detecting wireless networks' show the name assigned to your wifi router?
sorry i wasnt clear. My 2 laptops can connect to my wireless network fine. Its my desktop with windows xp that cannot. WHen i click "view available networks" it says none. I dont know why. I made sure Wireless Zero Configuration was set to start but it still doesnt work. i dont know why i cant see a list of available networks.
