Turning on Panasonic Vierra Plasma, ethernet?

If i switch from Wifi to Ethernet on my Panasonic Vierra Plasma TV, will I gain the ability to turn the TV on?

Model is the p65st50 and I see a few entries on this site about the wifi network shutting down when it goes into standby, so you can turn it off remotely but not on.
Does ethernet solve this?

It does have an ethernet jack
