I am running XP Home on a desktop computer with a high speed internet connection via cable modem. I'm noticing that while listening to streaming audio such as internet radio, my connection times out at 55 minutes. Reconnection is easy enough. But, the interruption is problematic because I sometimes like to save the broadcast to listen to it later. I've looked for a setting that would mediate this but cannot find any. Am I to assume this problem is stemming from the ISP who is terminating my connection because there is 'no activity'?
