Troubleshooting network connection errors on your Squeezebox is hard! Once the Squeezebox Duet is fully configured it is important to remember that you actually have two devices connected to your network: The Squeezebox player/receiver and the Squeezebox Duet controller!
If you eg. change network provider, router etc. you can easily set up your controller again, but you will have a very hard time reconfiguring or connecting to your Squeezebox receiver SBR as it is still configured for you old network!
In many troubleshooting situations the easiest and fastest solution is to do a full facotry reset and reconfiguration (as the full setup only takes about 1-2 minutes). Follow the steps provided here!
- Do a factory reset on you Squeezebox controller (Settings->Advanced Settings->Factory reset)
- Do a reset on your SBR by holding the led button until it flashes red (approx 10 sec)
- Go through the setup wizard on your Squeezebox controller and it should find your Squeezebox Receiver!
- Repeat the steps if you still can't find the Squeezebox receiver.
