I've got a Premiere+ (bought in 2017, model #4630XB) that I've been using with WiFi until now. I now have a nearby networking switch that's connected to several other devices (like the blu-ray player, TV, and A/V receiver), and I was successful in migrating them all to a hardwired connection. The Roku, however, consistently gives a connection error. I verified the cable is good, and have already tried restarting the Roku as well. Any other tricks that I'm overlooking?
