LanTurnOn Help and FAQ

This page is for Lanturnon version latest on desktop. It explains Wake-on-LAN basics, common terms, setup checks, and troubleshooting.

Getting Started

1. Add the target device in the app.
2. Enter and verify the device MAC address.
3. Ensure Wake-on-LAN is enabled in BIOS/UEFI and operating system settings.
4. Keep both devices on the same local network for initial testing.
5. Send a wake command and confirm the device powers on.

FAQ

What is Wake on LAN (WoL)?

Wake on LAN lets you power on a supported computer remotely by sending a network trigger packet.

What is a magic packet?

A magic packet is a small network packet containing the target device MAC address. Supported devices listen for this packet and wake up.

What is the difference between MAC and IP address?

MAC identifies the network adapter hardware. IP identifies current network location. WoL depends mainly on MAC.

Do both devices need to be on the same network?

For most users, yes. Remote wake over the internet is possible, but needs advanced router setup or VPN.

Why does my device not wake up?

• WoL disabled in BIOS/UEFI.
• Network adapter wake settings disabled in OS.
• Incorrect MAC address.
• Router/firewall blocking packets.
• Device is in a power state that does not accept WoL.

Which power states are usually supported?

Typically sleep/hibernate, and sometimes soft-off, depending on hardware, firmware, and OS power settings.

Is Wake on LAN secure?

On trusted local networks, generally yes. For internet use, prefer secure access methods such as VPN and avoid exposing WoL ports broadly.

Do I need a static IP?

Not always, but DHCP reservation/static assignment can improve reliability and reduce intermittent failures.

What is broadcast address?

Broadcast sends packets to all devices in a subnet. Some networks require WoL packets to the subnet broadcast address for consistent wake behavior.

Can I wake multiple devices at once?

Yes, if each target is correctly configured and your network allows packet delivery to each device.

Troubleshooting Checklist

1. Re-check MAC address in app and on target system.
2. Confirm WoL BIOS/UEFI option is enabled.
3. Confirm OS adapter wake options are enabled.
4. Test wake on same LAN first, before trying remote networks.
5. Temporarily disable network filtering to isolate firewall issues.
6. Reboot router and target machine after settings changes.
