How does Wake-on-LAN with TeamViewer work?

77% helpful (10/13)

You can turn on a sleeping or powered-off computer using TeamViewer’sWake-on-LAN feature. This means you can control an offline computer remotely by waking it up first, before you establish a connection to it. 

You can initiate the wake-up request from another Windows or Mac computer, or even from an Android or iOS device running the TeamViewer Remote Control app. 

Note: it’s not possible to wake up a Mac computer that is fully powered down, as Apple doesn’t allow this. Macs can only be woken up from sleep mode. Windows and Linux PCs, however, can be woken up from sleep and hibernation mode as well as being fully powered down, so long as the hardware supports this. 

Wake-on-LAN can be used through two different methods: 

A: Wake up a computer (hereafter called the target computer) via another computer within the same network. 
B. Wake up the target computer via its public address. 

Choose one of the methods depending on the circumstances.

A: Wake up the target computer via another computer within the same network

Choose this method if there is a second computer (eg. a server) within the network of the target computer that is turned on permanently. 

In this case you can use the second computer to wake up the target computer. The second computer acts as a kind of “middleman” to forward the wake-up request to the target computer. This method requires considerably less configuration effort than method B.

If you can answer the following questions with "Yes", this is the appropriate method:

  • Is the target computer located in a network?
  • Is the target computer connected to the internet using a network cable?
  • Is there a second computer (PC, Mac, Linux) located in the same network?
  • Is TeamViewer 9 or higher installed on both computers?
  • Does TeamViewer start automatically with the operating system on both computers?
  • Is the second computer turned on 24/7 (the operating system and TeamViewer is running)?

If yes to all the above, you can wake up the target computer in three easy steps:

  1. Configure the hardware of the target computer
  2. Configure TeamViewer on the target computer
  3. Wake up the target computer

Please refer to the TeamViewer Wake-on-LAN manual for a detailed description of how to set up Wake-on-LAN with TeamViewer.

B: Wake up the target computer via its public address

Choose this method if the target computer can be reached via a public address. This is the case if you have either a fixed, static IP through your Internet provider or if your router has a public domain address with the help of a dynamic DNS provider. 

In these cases you can configure TeamViewer in such a way that the target computer is woken through this address. The configuration effort of this method is higher and more complex than in method A, because you have to set up your router accordingly.

If you can answer the following questions with "Yes", this is the appropriate method:

  • Is the target computer located in a network?
  • Is the target computer connected to the network using a network cable?
  • Is the target computer connected to the internet via a router?
  • Does the router support port forwarding?
  • Does the router have a public address (either a fixed IP address or a public domain address)?
  • Does TeamViewer start automatically with the operating system on the target computer? 

If yes to all of the above, the following steps are necessary to use Wake-on-LAN via a public address:

  1. Configure the hardware of the target computer
  2. Configure the router for port forwarding
  3. Configure TeamViewer on the target computer
  4. Wake up the target computer

Please refer to the TeamViewer Wake-on-LAN manual for a detailed description of how to set up Wake-on-LAN with TeamViewer.

Can I use my tablet or smartphone to wake up my computer via Wake-on-LAN?

Yes, you can wake up a computer / laptop via Wake-on-LAN using your tablet or smartphone.

To do so, you must configure TeamViewer Wake-on-LAN via your router (DynDNS) or TeamViewer IDs as described above. This allows you to wake up your laptop, computer, workstation, or other devices that are running Windows or Mac OS X.

To wake up a computer, use TeamViewer 9 (or later) for your smartphone or tablet that is running one of the following operating systems:

Alternatively, use TeamViewer 9 (or later) for Windows or Mac OS X, or the TeamViewer Management Console.
