I am trying to make Wake-on-LAN for my home server, so far connected only by Wifi, Wake-on-Wifi seems to be extremely tricky, and it's unfortunately quite far from router and I am reluctant to start laying ethernet cables everywhere in a rented house. So I came across to powerline ethernet, that is LAN through house mains, using adapter like: TL-PA9020P AV2000 Gigabit Passthrough Powerline Starter Kit.
Question is, would Wake-on-LAN work through them?
UPDATE
My main concern is that what keeps this adapter powered? All they always on? What activates them? What concerns me, is comments like here, on Netgear Powerline Adapters FAQ:
Q: Why my Ethernet printer/Nas is not waking up when connected to my powerline?
A: The Powerline adapter can only be awoken by a device that is connected to its Ethernet port, not via the power outlet. So, if the Powerline adapter is asleep, it can't pass data to the printer (or NAS), only FROM the printer..
