I don't know if this helps - but you might be able to set exactly what your network adapter responds to in order to wake up your computer. Try going to Device Manager and opening the properties of your adapter, and look for an Advanced tab.
Mine for example (a Marvell device) has an entry called Wake-Up Capabilities, with the options of None, Magic Packet, Pattern Match, Magic Packet and Pattern Match and Link Change.
If yours has a similar setting, try changing it and seeing if that helps.
