I have a fairly new Dell desktop stand-alone system with Vista Home
Premium. I don't use standby or sleep; when it is on, it's always full
power. Usually, I shutdown once each day, but occasionally not.
I've noticed that if the system is powered up for more than 24 hours or
so, it will disconnect from the internet (AT&T DSL with a Speedstream
Is this behavior normal, perhaps security related?
How can I reconnect to the internet without rebooting?
