I did look on the "My Downloads" page + "Download Drivers" link but it only shows/downloads Wireless Select Enable Disable(WSED), i'm not even sure what that is and cannot see any other drivers.
The download drivers link doesn't usually offer all drivers,possibly an updated driver maybe.
The driver disk you are supplied with will suffice to get you going,
If necessary you can update drivers from manufacturers websites,but you shouldn't really need to do that,
unless having problems.
