The Wake on LAN feature wakes a PC or Server from shutdown mode via LAN if it is connected to a power cable. The Wake on LAN works by sending a "magic packet" from a WoL client which can be used to turn on any computer from the same subnet/network that receives the magic packet.
A computer's hardware does have to support Wake-on-LAN with a compatible BIOS and network interface card, so not every computer is automatically able to use Wake-on-LAN.
We would recommend that you check if the model of your network card accepts standard magic packets.
How Wake On Lan works
- WOL uses port 12287. (UDP). In case this port is not available, we do not try other ports
- The Magic package is sent as Broadcast (i.e 255.255.255.255)
- Commands are sent to each Mac address of the 'Sleepy' Agent.
Wake on Lan Requirements
First, we have to make sure that WOL is enabled in the BIOS of each device, please refer to the manufacturer's documentation.
We must also "Enable Wake on Magic Packet" for the Ethernet Adaptor.
In the Power Management section, all three options must also be enabled.
Wake on Lan in Atera
- Agents should be located under the same customer in Atera.
- You must have at least 1 online Agent in the network.
- The machines you want to wake up must be in the same subnet/network.
- Ensure the devices are not missing an internal/external IP address in Atera (the 'IP Address' can be found on the Device page).
- You must enable the wake on LAN mode in the bios of each machine before this function can be used.
- Once the above is set, you need to pick one of the available agents from the drop-down list.
