onboard network card not functioning

Hi,

Dell has not tested XPS 730 with Windows 8. For more information on this you can check the link: http://dell.to/U7cW0Q  First step you can try is to check in BIOS if the Integrated NIC is enabled by following the steps below:

• Restart the computer.
• As soon as you see the Dell logo, start tapping the ‘F2’ key on top of the keyboard.
• If you wait too long and the Microsoft Window appears, then continue to wait until you see the Windows desktop. Now shutdown your computer and try again.
• After this a new window would appear. You can only use the arrow keys of the keyboard to navigate between the options as the mouse is not functional in this mode.
• Navigate to 'Advance' tab, enable 'LAN0 controller' and 'LAN1controller'
• Press F10 to save settings.
• Press Esc to exit BIOS and restart your computer

Once the Integrated network card is enabled, you can install the driver for Ethernet controller from link: http://dell.to/ZRaDIf

Steps to download drivers:

• Click on “Download File”.
• Select “For Single File Download via Browser”.
• Click on “Download Now”.
• Save the driver on your desktop.
• Once the driver is downloaded on the desktop, right click on it and select “Run as administrator”.
• Follow the prompts on screen and restart your computer.
