# Wake on LAN

> Turn on or wake a sleeping computer on your network from JetKVM, locally or through JetKVM Cloud.

Wake on LAN turns on a computer, or wakes it from sleep, with a network message called a magic packet. JetKVM sends it on JetKVM's network, so you can wake any computer there, even when you're connected through [JetKVM Cloud](https://jetkvm.com/docs/networking/jetkvm-cloud).

For a computer connected to JetKVM over HDMI and USB, it's an easy way to turn it on remotely. For full power control, including a forced shutdown, use the [ATX Power Control](https://jetkvm.com/docs/extensions/atx-power-control) extension.

## Turn it on in the BIOS or UEFI

Restart the computer you want to wake and open its BIOS or UEFI setup. Find the Wake on LAN setting and turn it on. Where it is and what it's called depends on the computer; look under power or network settings, or check the manual.

Wake on LAN usually needs a wired Ethernet connection.

## Turn it on in the operating system

**Windows**

1. Right-click the Start button and open **Device Manager**.
2. Under **Network adapters**, double-click your Ethernet adapter.
3. On the **Power Management** tab, check **Allow this device to wake the computer** and **Only allow a magic packet to wake the computer**.
4. On the **Advanced** tab, set **Wake on Magic Packet** to **Enabled**, if it's listed.

**macOS**

1. Open **System Settings**, then **Energy**, or **Battery**, then **Options** on a laptop.
2. Turn on **Wake for network access**.

**Linux**

1. Find your Ethernet interface, such as `eth0` or `enp3s0`:  
```  
ip link  
```
2. Turn on Wake on LAN for it:  
```  
sudo ethtool -s <interface> wol g  
```
3. This lasts until the next restart. To keep it, turn on Wake on LAN in your network manager's settings for the connection.

While you're there, note the computer's MAC address. On Windows, run `ipconfig /all` and look for **Physical Address**.

## Add it to JetKVM

1. In JetKVM's web interface, click **Wake on LAN** in the top bar.
2. Click **Add New Device**.
3. Enter a **Device Name** and the **MAC Address**, then click **Save Device**.

JetKVM saves the device, so it's there next time, from any browser.

## Wake it

Click **Wake** next to the device. A computer that's off usually takes a few seconds to start.

## If it doesn't wake

* Check that Wake on LAN is on in both the BIOS and the operating system.
* Shut the computer down normally. On Windows, a full shutdown with Fast Startup on can ignore magic packets; try sleep first, or turn off Fast Startup.
* If the computer is on a different subnet or VLAN, delete the device in JetKVM and add it again with **Broadcast Address** set to **Custom subnet**. Enter that subnet's broadcast IP, such as `192.168.2.255`.
