All was fine, I was happily listening to music streamed to my amp from my vista PC. Then it stopped. And now I can't get the squeezebox to connect to my pc. It sits there with a slow flashing red light.

I have a feeling that my PC/Linksys Router unilaterally decided to re configure themselves and try as I might I can't get it to connect again.

How can this happen without me actually touching anything?
