These BIOS settings didn't work for me, I can only boot from sleep/hibernate, not from shutdown with my Z87-Pro. What other BIOS settings do you have enabled? Are you using an ethernet connection, or connecting via Wi-Fi?
Also, BigShowJoe, you may want to look into setting a static arp list entry on your router. Some routers allow you to telnet in and execute commands such as "arp -s [computer IP address] [computer MAC address]", this will set a static arp list entry for your PC, and it will remember the IP/MAC address if the PC has been of for awhile.
