I'm currently following this guide (<https://technet.microsoft.com/en-us/library/ee851581%28v=ws.10%29.aspx?f=255&MSPPError=-2147217396>) to enable Wake-On-WLAN, but the option "Allow this device to wake up the computer" in the device manager is greyed out. I tried to enable "Power on by PCI-E" in the BIOS (Motherboard ASUS Z97-PRO GAMER) but it didn't help. In the linked article is also stated that the function might not be available for my network card if the option is greyed out.
My network card is the TP-LINK TL-WN881ND.
