Disappearing Network Connection

[Guest]

OS= XP w/ SP2 (up-to-date): For the past two weeks, on several occasions
(yesterday and today included) after the computer has been shut down
overnight, the LAN connection is gone upon morning boot. Restore to a system
checkpoint results in "System cannot be restored to [that] checkpoint. No
changes have been made . . ." But the LAN connection reappears when the
computer finishes booting.

Ad-Aware SE Personal, Spybot, Windows Defender and AVG Free (all up-to-date)
show nothing as of this morning. AVG Free did find and clean a trojan (first
one ever) in, I believe, Windows System32 a few days ago, which was after the
first 2-3 occurrences of the network-connection disappearing act. I've tried
to update the driver, but Windows reports none newer available. I've looked
on the manufacturer site, but get nothing but instructions on how to install
with a CD, which I don't have. So far, the connection has not been lost while
the computer is booted.

The Ethernet card is in a PCI slot and the driver is XP approved, having
been installed and updated at least once since card installation. Card is
TRENDNet TE100-PCBUSR.

The local ISP technician called the problem a "gremlin" which probably would
continue to do it's thing. Any other professional ideas will be received with
appreciation.

Computer is 6+ years old. Network card = 2+ years.

Hi Marty,

Could it be as simple as a modem reset? I know the one I use sometimes just
needs to be turned off and disconnected for a couple minutes, and all is
fine. And just as you stated, it never goes down while online. It usually
will happen overnight, when all is asleep.

Thanks, Curt, for the response. First time the connection disappeared I
rebooted the modem but that had no effect. Didn't leave it off for a couple
of minutes, but the modem, an all-in-one modem and router, is used by others
in the house and is never turned off, not even at night. So I surmise the
problem is somewhere else.

Perhaps I should clarify what I mean by "connection disappeared". The
occurrence is in my computer; viz., Control Panel/Systems/Network Connections
shows no LAN icon. And apparently the Ethernet Card is O.K.
