It shouldn't be a problem if both show connected as ethernet is the default networking connection however you can try a possible workaround to the no wifi on/off switch.
1. ensure you have an ethernet connection
2. enter the edit function to your wifi connection.
3. clear all the boxes in wifi connection and exit out. If there is a auto connect checkbox make sure it is unchecked.
If all goes well you should only have an ethernet connection remaining.
For the past few months I am getting intermittent pop up messages on my TV.
1st one says Wired LAN disconnected, then another message pops up and says Network connected. I have been calling my cable carrier Spectrum and Techs have been here and can't find problem. Also I went to check my wifi on my TV and my user name and connections aren't showing up all of a sudden. This TV was just purchased May 2017. What is going on and how to resolve!!
Yes it is, with XPLAY you can direct stream/play (without transcoding) 4k content, while PLEX official app cannot do that. My PLEX server runs on a raspberry pi3, so transcoding is out of the question...
