My Soundbridge basically doesn't work. It will connect to an internet radio station, play for 14 seconds, and then rebuffer. This goes on until I turn it off, fighting the urge to throw it across the room
Is there anything I can do, or do I just chalk this one up to experience?
The device in question is connected to my PC via an ethernet cable. I'm using a Linksys WRT54G router.

well, i think the problem you are having is bandwidth related.

either you don't have enough bandwidth from your ISP or your LAN is not fast enough to keep up with the streaming.

Does playing music from your PC work OK ? My soundbridge used to be fine with MP3 but once I went flac, wireless bandwidth wasn't enough.
