I've got AT&T DSL, which is on all the time. Nevertheless, after turning on the computer for the day, if I don't actively use the Internet for a while (about a half hour), I lose my connection. In order to reconnect I've had to restart the computer. What program fluke may be causing the computer to disconnect like this? What can I do to ensure that I stay connected? AT&T says it's not caused by them, and I've verified this to be true. I've contacted Compaq, but the guy in India has no solution. I've run Norton virus scan, Spybot, and Spysweeper, all of which indicate that I'm not infected with any malware. My operating system is: XP updated with Service Pack 2 and all subsequent critical updates.
