Go to this site and find your drivers.http://www.realtek.com.tw/downloads/
Download them to a known folder.
Then in device manager expand the driver with the exclamation mark.
Right click it and choose properties. then update driver. have it go to the folder you downloaded the drivers to and install.
Or just double click the realtek driver .exe you downloaded and it should install.
Edit: I updated that link to the main menu. The origional link was to my drivers link.
