Enable the hardware first, then add the system in Wake Up Support.
- Open the Dell BIOS/UEFI setup and enable Wake-on-LAN. On many Dell systems this is under Power Management.
- Enable any option that allows wake from the built-in wired network adapter. Use LAN only unless the site specifically needs wake from another power state.
- In Windows Device Manager, open the Ethernet adapter, then enable wake options in the Power Management and Advanced tabs.
- Add the system in Wake Up Support using the system name, MAC address, optional IP address, subnet broadcast address and WOL port. Port 9 is the usual default.
The broadcast address should match the subnet, for example 192.168.154.255.
