hi,
Thanks for all the suggestion.
Answer to DMan's question:
If I power off the cable modem for 1 minutes , and
case #1), power off the computer, and power on the computer, and
power on the cable modem. the connection will
establish again.
case #2), power on the cable modem without off/on the PC, sometime,
the connection can be re-establish.
case #3), I also tried to just power off/on the PC only, and sometime
the connection
can be re-establish. But most of the time, this method would not work.
The sure way to re-establish the connection is case#1.
There were time if I wait long enough (for several hours), the would
re-connect
automatically. Again, this does not seem to happen consistently.
So, I do not know if it is the modem, the nic card, the cable connection,
or
just AT&T... THis problem happens on Windows/NT 4.0 also...
THanks!

If you power off the cable modem, wait a few minutes, and then power
it back on what happens? With my ADSL modem I have no problem at
all. Also, are you using PPPoE or DHCP? I have read that DHCP is
more robust than PPP because a connection can be dropped for some time
then resumed as if nothing had happened whereas a PPP connection is
broken if the connection is dropped at all.
