Wireless Autodetect not working

Windows XP SP 3, Wireless autodetect not listing detected networks. Can connect to wireless if settings added manually. If a repair performed then setting have to be added again to connect. Wireless cannot display network even if it is connected, yet the message “wireless networks have been detected” is still displayed. Using windows zero config. Already tried updating driver, SFC /scannow, all Windows updates (laptop started at SP2). Any Ideas?
