Wake on Lan Not Working

I cannot get my Inspiron 3521 (Windows 7) to wake up using WOL. I have:

• Ensured that my Internet is only coming to the machine through a wired connection.
• The laptop is connected to a power source at all times.
• I have consulted my BIOS (A10 Inspiron 3521) and I do not see any relevant settings and from what I can tell online WOL on should be enabled by default.
• The software sending the magic packet is using the correct MAC address for the laptop and the IP address for the wired network adapter.
• I am truly putting the laptop to sleep, and not into hibernate mode or shut-down. I thought that this was all that was required in order for a WOL to work on a local network, but I appear to be missing something.
• I am able to wake my non-Windows computers on this same network using WOL.

Any help on this is greatly appreciated! Many a frustrated hour has already been spent on this and I am at my wit's end.

Please do not refer me to the Tech Center, as they have confirmed that they do not provide customer service support.

Thank you in advance!
