> Go to their website.
> On their first window, click their search box and search SVE14A1V1EB 7.51.116.2012 to get the driver file. Click the download bar (snapshot below)
> 2nd window: Verify you're not a robot then click a download bar again
> 3rd window: Click the download bar again to start the download (they REALLY make sure you're not a robot nor can simply give away download links)
Let's see if this gives you an ethernet connection. If it does, you can also try right clicking the other devices->Update Driver. See if Windows finds it for the drivers online. Otherwise we'll look back at driverscollection
