The IP is listed on the SDcard or written on a piece of tape on the machine. That should be how you connect to it. It is not automatic.
Thank you so much for the help.
There is a 188 on the card. I've tried a direct connect, laptop ethernet to miner ( as I do with my antminers ) as well as using angry ip to scan the network. Nothing.
The light on the router does not show anything plugged into the port.
