Homelab warrior enables wake-on-lan for couch-bound server access, gets schooled by ancient ubuntu laptop's power betrayal

A technology enthusiast recently set up Wake-on-LAN, or WOL, on their Windows desktop and Ubuntu laptop, allowing them to turn on their devices remotely. The goal was to access their homelab and avoid keeping machines powered on 24/7. WOL enables a computer to be powered on by sending a special packet over the network, requiring a wired Ethernet connection, BIOS/UEFI support, and OS-level configuration. The enthusiast found that desktops work reliably, while laptops may have limitations due to hardware constraints. To set up WOL, one must enable the feature in the BIOS/UEFI and configure the network adapter. The process involves installing ethtool on Linux systems and using commands to enable WOL. With WOL, users can send a magic packet to wake their device, and it can be done locally or over the internet using a VPN for added security. This technology has significant implications for home automation and remote device management.
