Please do your homework in regard to allowing your Mac or PC to be turned on remotely by all the naughty children out there.
Wake a Mac from a PC:
First, get the necessary information from your Mac by first going to System Preferences, then Network. Select your built-in ethernet and click "Configure...". Under the TCP/IP tab, write down your IP Address and Subnet Mask. Click the Ethernet tab and then write down the "Ethernet ID." Your numbers should look similar to the following (hypothetical of course) example:
- IP: 10.3.52.88
- Subnet Mask: 255.255.255.0
- Ethernet ID: 05:0b:95:87:10:3c
Wake a PC from a Mac:
On your PC, Right-click on "My Computer" on your desktop and click "Manage". Choose "Device Manager" then find "Network adapters" on the list. Click the + and launch your ethernet card properties box. Under the "Power Management" tab, make sure you allow yourself the ability to bring the computer out of standby. (not sure how this is done on your particular card). Close this window. Now go to your "Start" menu and choose "Settings" then "Network Connections" then "Local Area Connection." Click the "Support" tab, then the "Details" button. Write down the "Physical Address." This address will look like the "Ethernet ID" number earlier. Close this window. Put your PC on standby and go to your Mac.
Download the "WakeUp" utility. Add a computer to the list window and put in your PC's name and Physical Address number. Click the "Wake Up" button and your PC should wake up accordingly.
I hope this works for you and helps to make things easier in regard to WOL and WOMP commands.
