Wake-on-LAN requires various other settings to be set correctly. Your firewall and antivirus programs must be set up correctly, as must your router, your machine’s BIOS, and your operating system. As far as the driver settings go, ensure that you have the following set:
- In Device Manager > your Ethernet Adapter > the Advanced Tab
- Shutdown Wake Up set to Enabled
- Wake on Pattern Match set to Enabled (depending on your setup, Wake-on-LAN may work with this disabled)
- Wake on Magic Packet set to Enabled (depending on your configuration, Wake-on-LAN may work with this disabled)
- SWOI set to Enabled (this is optional, and enables specific applications to wake the machine from external IP addresses over the Internet. This should not be needed for Wake-on-LAN, but may be desirable for some.)
- In Device Manager > your Ethernet Adapter > Power Management
- Allow the computer to turn off this device to save power should be checked.
- Allow this device to wake the computer should be checked.
- Only allow a magic packet to wake the computer should only be checked if the computer wakes from sleep at undesired times, and you want to restrict this behavior to only waking from a magic packet.
Please note that, with modern Dell and Alienware machines, the Power Management options will be grayed out because these machines use Modern Standby. With Modern Standby, the computer is always connected to the Internet in every sleep state. However, Modern Standby does have its own set of wake sources. You can read more about Modern Standby wake sources by clicking here.
If those settings are all set correctly, then the network adapter is ready to go for Wake-on-LAN. Note that the machines have to be on the same subnet, and Wake-on-LAN may not be possible if there is any separation between the devices, other than a single router.
If you are unable to use Wake-on-LAN despite having all of the above settings correctly configured, there may be some additional configuration needed in the BIOS of your specific motherboard or machine. For further information, you will need to contact the computer or motherboard manufacturer for support.
