They are both the same model, purchased one year apart. We need to reconnect the tv to Wi-Fi every time we turn the older set on. Our Wi-Fi is not great, live in a very rural area that has limited reliability. If the Wi-Fi goes out while we are watching (say, for a minute or so), the older tv has to be reset up again. The newer tv patiently waits and when the Wi-Fi is back up the new tv starts streaming again. The older one totally stops, and when the Wi-Fi is back up may or may not connect to the Wi-Fi. We get these error messages that make no sense since the newer tv is working fine at the same time. We know we don’t have restart the modem.
