     Install or replace the drivers as necessary. For more information, see the NIC documentation.

   • Try another known good network cable.
   • If the problem persists, use another connector on the switch or hub.
4. Ensure that the appropriate drivers are installed and the protocols are bound. For more information, see the NIC documentation.
5. Enter System Setup and confirm that the NIC ports are enabled on the Integrated Devices screen.
