local network uplugged error

[hotcoffee]

My external modem (provided by my isp) was struck by
lighning this weekend. The modem has been replaced
however I still cannot connect to the interned using
enet, only usb...The local area network connection says
that a network cable is unplugged. I changed all of the
cables. They are not unplugged. I had my isp help me run
IP config and it showed disconnected with and without an
IP address which led us to think maybe the network card
is fried. My warranty computer support had me uninstall
and reinstall the network card. It was recognized and
reinstalled but still says disconnected so they think it
is an isp problem. I am logged on as admin but the repair
option is not available for this connection. Anyone have
any suggestions... Windows XP, Hewlett Packard PC
Thanks, Heather

It sounds like you have the wrong type of cable plugged into your NIC. Did
the ISP check this? I believe you need a cross over cable.

Thanks for the suggestion however, the cable and enet
worked fine before the lighning strike. I replaced the
cable with the cable that was sent with the new modem
(same kind of cable). One also suggested that maybe it is
a software issue however everthing was fine until the
lighning thing. Heather

The network card might be fried. Since a new one is so inexpensive
(around $10 at computer and office supply stores), I'd try a new one.

If the old network card is integrated into the motherboard, disable it
in the BIOS. If it's a PCI card, un-install it and replace it with
the new one.

Until you run a diagnostic for that NIC, then no one can
really say hardware is damaged. Operating System only talks
to NIC computer. NIC computer talks to network wires. Only
way to truly test hardware without potential software
complications is the NIC diagnostic.

First diagnostic will check out NIC computer functions.
Then it must talk to another NIC located on same network.
Here is the rub. That other NIC must be same manufacturer so
that same diagnostic runs on other, known good NIC. Without a
good result from this diagnostic, then you are stuck guessing
on everything. Best that two computers be interconnected
without using a hub. This would be beyond most users; should
be performed in the repair lab.

However you have additional important facts. Surge did not
just come in on phone line, damage modem, then stop. Surge
damage means first the surge found a complete electrical path
to earth ground via your machines. What was the incoming and
outgoing path? Only after a surge was passing through
everything in that path, was something else damaged.

So what else was damaged? If surge was either incoming or
outgoing on NIC, then what was the other NIC component
(possibly damaged) in that surge path? The answer to this
question better identifies failure to hardware. It will also
recommend anything else you should replace (or make plans to
replace) - since that component is also likely to fail.

Most typical source of incoming surge is AC electric because
so many buildings still don't have 'whole house' protectors
AND make surge damage easier by installing plug-in
protectors. External modem would have been damaged by surge
from AC electric, through modem, to earth ground on phone
line.

Another destructive path would be AC electric, through
motherboard ground, to earth ground via network. Is something
else on that network also damaged? If yes, then most possible
alternative is replace NIC - and verify that hub port also for
damage since surge via your NIC would have also passed through
that hub.
