I'm running WinXP Home Edition. I have DSL through Verizon.

At various times, I lose my connection to the internet. I've
called Verizon twice, and both times they say they've checked
and all is fine from their perspective.

I'll be on the PC on the internet, and suddenly I just lose
my connection. I don't even have to do anything. Sometime
I'll just sir down & try to access the internet or email, and
my connection is gone.

If I reboot, it's back.

I have no idea what to look for here.
