局域网唤醒 Powershell 脚本不起作用

Question

I've been trying to wake a computer on LAN from a shutdown state. The computer that is sending the WOL request is a windows 10 machine and the machine i'm trying to wake is a Windows 10 machine. I've tried a few scripts that I've found on the internet most of the scripts use the .net class UdpClient

I've made sure the computer I'm trying to wake has wake on LAN enabled on both the BIOS and the NIC.

The network subnet I'm on is a 255.255.0.0 subnet. The IP adress is dynamic and is assigned via a DHCP server.

The Script I'm using is:

WakeUp-Machines – A PowerShell script for Wake On LAN

So far it's not waking from LAN, Any advice on where I might be going wrong or A script which is sure to work...

Cheers,

A Walter

Answer 1

The script is working. The problem was not with the script but with the computer receiving the magic packet. The problem was being caused by windows Fast Startup and it required me to turn this feature off.

The article below outlines all the settings needed to enable wake on LAN.

Thanks to Colyn1337 for their useful comment which lead me to solving my own problem.

Run the box you want to wake on lan and install a packet capture, like wireshark. Even though it's running, send a WOL request... does it show up in the pcap? It's possible a network device between you is dropping the packet (quite common actually) – Colyn1337

I had this problem, too. On my dev machine the "Wake On LAN (MagicPacket)" app would wake the target machine, but none of the various PS1 scripts worked. But my dev machine was on the ASUS router's VPN. I stopped the VPN connection, ran one of the PS1 scripts, and it worked.
How can i improve the script to work even when my dev machine in on the VPN?
