After installing Windows XP Home last night, I updated to SP3, installed drivers from toshiba.com. However, installing the driver for Ethernet controller didn't work from toshiba.com. Realtek ethernet is listed and working in device manager. This ethernet controller with yellow question mark maybe from the wireless card? The wireless xp utility is not in the system tray. I have an atheros internal wireless card. This is a Toshiba Satellite A25-s2792 laptop. any help, I would be grateful.
