✨ Wake-on-LAN Magic Packet
Wake-on-LAN lets you boot a sleeping computer over the network. The magic happens via a "magic packet" — a UDP broadcast containing six 0xFF bytes followed by the target MAC repeated 16 times. This tool generates the exact bytes for any MAC. Send via netcat, your router's WoL feature, or a WoL app.
Examples
00:1A:2B:3C:4D:5E102-byte hex packet (FF FF FF FF FF FF 00 1A 2B 3C 4D 5E 00 1A 2B 3C 4D 5E ...)Frequently asked questions
Why won't my computer wake?
Check BIOS/UEFI for "Wake-on-LAN" or "Wake on Magic Packet" — often off by default. On Windows, also enable in the NIC driver: Power Management → "Allow this device to wake the computer".
WoL over the internet?
Possible but requires router config: forward UDP 9 to the target's LAN IP, and know the WAN IP. Most home routers also need a static ARP entry mapping the target's MAC since the device is asleep and does not respond to ARP.
