UEFI Computers
Troubleshoot Network Connection
• In order for preboot authentication to succeed on a computer with UEFI rmware, the PBA mode must have network connectivity. By
default, computers with UEFI rmware do not have network connectivity until the operating system is loaded, which occurs after PBA
mode. If the computer procedure outlined in Pre-Installation Conguration for UEFI Computers is successful and is congured properly,
the network connection icon displays on the preboot authentication screen when the computer is connected to the network.
• Check the network cable to ensure it is connected to the computer if the network connection icon still does not display during preboot
authentication. Restart the computer to restart PBA mode if it was not connected or was loose.
