Haven't you posted about this before ? Who do you have DSL through ? I'm not sure it matters. If you aren't using the built-in internet connection tool that comes with Windows XP, you are probably making a mistake. I have SBC Yahoo and after I uninstalled their crappy connection software, I haven't had any problems with disconnection since. I stay connected for 3 days straight easily. If you have SBC Yahoo, uninstall anything with the name Broadjump in it and use the built in internet connection device that windows xp has. Go to
