WIndows 10 How to wake up another computer in the network?

I have two computers connected to the same router (Wifi and wired). Each computer is set up to go to sleep after 30 minutes of inactivity.

I would like to wake up the other computer, vis versa without having had to walk upstairs to turn it on, which defeats the purpose.

Can you help, please? Thanks.

I'm not sure how to turn on a computer connected using wifi, but it's simple enough to do to a computer connected by an ethernet cable. Now this is by memory, later when I'm home can be a little precise. Make sure you have installed the drivers for your nic, enable wake up in the nic configuration, enable wake up lan in the bios and then you will need to send a magic packet the the lan ip of the computer.

This is the only way I know about, but its been a long time, maybe someone knows an easier way.

When you have time, can you talk a little more about "sending magic packet".

Basically you just use a program that directs packages to a specified ip, the nic receives the packages and turns the computer on.

Download a program called "wake on lan magic packet" and install on the computer which is going to be used to wake another computer, run it filling out fields and then clicking wake up.

Have you already found wake up options in the bios and the nic configuration?

I will give it a quick go now so I can get myself reacquainted with the procedure.

Edit: FYI this will also wake up a computer that has been shutdown.

I did read your message and googled help. I am a little confused though.

1. The machine "R" is the one I want to wake up, and the machine "S" is the other machine I want to use to wake up R. I changed the network setting in R to enable WOL and enabled the magic packet. I opened the ethernet network setting and got the MAC info from R.

2. I downloaded the WOL software in machine S. I assumed that the WOL software should be in S to send the magic packet to R. Right?

3. When I open the WOL software, I create a new host, right? I can give it a name like "To wake Desktop". I can leave the Group and Note blank, right?

4. On the "Wake Up" tab, I have the MAC address and the IPv4 address that I can fill in. But I am lost from this point on. Can someone help me along?

And when I clicked on the newly created host, I got this error message and machine R is still not accessible.

What version are you using of Windows 10? Is it "Home or Professional". The Professional and Enterprise editions are the only ones that have Remote Desktop enabled.

OK. I played around with it a little bit and am able to wake up R from S. I even am able to log on remote desktop and operate R from S.

S is on WiFi and R is wired.

I duplicate the set up and try to wake up S from R . But I was not able to do it. It kept showing "Host is offline" after the magic packet was sent.

Is there anything else I should do?

I am able to access the laptop (on Wifi connection) from the desktop via "remote desktop". But I am not able to wake the laptop up either when it is on WiFi or wired. It seems that the HP8470p goes into a much deeper sleep.
I cannot find any power management in the BIOS. I changed the setting of the NIC properties from Device Manager (the same way I did for my desktop).

Any suggestion?

I did a bit more reading on WakeOnLan. It seems that it's designed for computers connected via Ethernet (wired) in the same network.

With that, it's no surprise that it doesn't work with my WiFi connected laptop. So the magic packet doesn't reach the laptop to wake it up. But when the laptop is awake, I can still use the remote desktop from the desktop computer to simulate the laptop.

I need to figure out why it is not waking up even when I wired the laptop. I wonder if it only works with the NIC in a desktop?

Maybe I wasn't clear enough. The program works when sending a magic packet Wi-Fi to Ethernet or Ethernet to Ethernet, but not the other way around or Wi-Fi to Wi-Fi. This program as far as I know only works to wake up a computer connected by an Ethernet cable, but packets can be sent by wifi.

I ask because if you can't then the computer most likely doesnt support this feature, I have never tried waking a laptop so......dunno.

There is no such option on the BIOS of my HP8470p. Maybe it wasn't supported as you suggested.
But currently it works just well because 90% of the time I would be trying to wake up the desktop (wired) from my laptop anyway.

If there's no option in the bios then I think it won't be possible to wake the laptop even when it connected by an Ethernet cable.

So it's working and you can wake up the desktop using the laptop?

Unfortunately I do not know of a way to wake up a wifi devices, sorry I can't help more but maybe someone else knows something.
