windows - Why my computer wakes up from the network card?

I've noticed my computer receiving a wake signal from my network. I am on a LAN with only few devices connected on it: printer, smart phones, nas, router + few other computers...

I checked the status of the last wake with power config:

C:\>powercfg /lastwake
Wake History Count - 1
Wake History [0]

  Wake Source Count - 1
  Wake Source [0]
    Type: Device
    Instance Path: PCI\VEN_8086&DEV_1503&SUBSYS_849C1043&REV_05\3&11583659&0&C8
    Friendly Name:
    Description: Intel(R) 82579V Gigabit Network Connection
    Manufacturer: Intel Corporation

So I disallowed my network card to wake my computer.

My question is why do I receive wake signals from my network? What can be the origin?
