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!!
