This is slightly off-topic, but the Chromecast Ultra, with the Ethernet connection, is an absolute beast. I'm lucky enough to have Ethernet in my whole flat (two drops in every room), and a gigabit internet connection. When I launch a 4K HDR video on YouTube, it literally takes less than two seconds to start playing. In comparison, the YouTube app on the TV takes 5-10 seconds to start playing. The TV is hardwired as well. Please note that the Chromecast only has a 100Mbit ethernet port, same as a RPi, or most smart TVs. I thought the original Chromecast was great. But even if you have a great wifi setup, get the Ethernet power plug. It will change your Chromecast. You don't need the Chromecast Ultra to use the Ethernet feature, just a second generation Chromecast (the round one)
