I've been trying to reinstall my Realtek USB 11g/n connector since reinstalling Windows XP. Although the driver and utilities have apparently been successfully installed from the disc, the icons shows:
a) No Realtek 11n USB wireless LAN.
b) Ralink wireless LAN card does not exist.
When I put the drive in the USB port, the configuration utility does not start either, nor does it launch from the desktop icon. It flashes and disappears. What can I do?
