Squeezebox Internet radio 'sputtering?

Squeezecenter is selected when you want to use your computer as a Server, in other words, access your iTunes Library, it will also play internet radio stations, and your Computer (Server) has to be on all the time, also make sure that Squeezecenter is enabled to start automatically when you reboot your computer.

Squeezenetwork is used only for internet radio, and a computer is not necessary, you only need an internet connection.

You should not be having this problem with a wired Ethernet Connection, unless the cable is very long, like way over 100ft, as packets could sometimes get dropped. I agree with above comments; check your router, ethernet cable, and security settings on your router, sometimes routers think they're being attacked and then they usually just block further communications totally, as opposed to starting and stopping. It sounds like a buffering issue. Do you have kids at home who do a lot of online gaming as I've heard that could also steal some bandwith.

Good Luck!

I forgot to ask you this. Did you first use your Duet with a wireless connection and then change it to a wired connection? Because if you did, you have to go into the settings on the remote and reconfigure it for a wired ethernet connection.

Just simply plugging in an ethernet cable will not change it to a wired setting. So if this is the case, then you would have an ethernet cable plugged in, yet still be connected to a wireless network, and of course the wireless connection would be causing your buffering problems.

I’ve faced the same issue the day before yesterday. my router is working smoothly now, I am even doing live streaming. I found this article on how gaming routers work very fruitful for me.
