As I have mentioned elsewhere, my Chumby Classics, connected by ethernet, are very prone to disconnecting themselves and won't reconnect automatically.
Today, however, something a bit odd happened. I was listening to internet radio via YouStreams and had been for several hours. I looked up and noticed that the Chumby had switched to the default clock, and sure enough on the Control Panel it said it was Not Connected. All through this the music played without a stutter. A few minutes later, the Chumby reestablished its connection and the widgets came back. Radio kept going throughout.
