If your streamer is not connected to your internal network, nothing will work. Check your router connected devices to see if it’s on the LAN. I don’t know what the device will be called on the device list on the router but you should know what ip address your streamer is.
If you have another computer, ping the ip address of the streamer. You should get bytes of data received at what speed if it is on the lan, or it will say ip address not found, then you know it’s not connected
