(Help!!)Windows Vista can't detect my ethernet controller, Any Ide

Hello there,

My laptop is Toshiba M55 S1001, the entry level laptop. I tried to
install Windows Vista and it work fine so far, the only thing is when I hit
the device manager and it tells me that the Ethernet controller can't be
installed correctly ( has a question mark) in device manager. It seems that
I can't connect to internet if I can't install this controller right. Any
idea I can't find a driver to fit this baby??
