Thanks again. I hooked it up to a TV as suggested, and it had booted up, and an IP address was shown. Strangely, the Roon app on my iphone then found the nucleus right away. I had re-started the nucleus a couple times before trying this, so not sure what’s different other than the ethernet jack I was plugged into. Also, after the nucleus was seen, it said both the nucleus and the controller needed an update, which I then allowed. Maybe that was it. I moved the nucleus back to its normal location and it’s working just fine now. Thanks all for your help.
