Replace Logitech Squeezebox Duet

Are you running Logitech media server on the computer? Squeeze devices connect to that.

Yes. My setup has run for many years. A week ago we had a 5 hour power outage. Since then the remote cannot find the base. All it sees is Squeezebox.com. I have pushed the button on the base to make it blink red until my finger is red. I have set the remote to factory status many times. I have connected it to my network many times.  The remote just never lists my base as one of the Players. 

Have you tried using a web browser on a computer on your network if you have one as the controller to connect to LMS and see if your Squeezebox duet shows there?
In any case, most streamers you would replace an older SB with wiki use an app that runs on a smartphone tablet or other device as controller/remote and will display Whatever art or tags are available.

What url for the browser? I can open the server app on the pc but have not seen an option for a list of players.
