cannot establish IP connection with the cable provider

[isser6]

Dear PC experts out there,
For unknown reasons, my Win XP Home desktop PC (HP Pavilion 750n)
cannot connect
to the Internet. This happended immediately after a power surge on
Sunday (five days ago). I have not made any changes to the PC.
The computer shares a router with 2 other laptop PCs at home via a
belkin wireless connection. The internet cable is routed into a modem,
the modem is connected to a router, and the router is connected to the
troubled desktop computer via an Ethernet cable. The same router also
provides wireless transmission to the 2 other laptop PCs. These 2
other PCs have no problem connecting to the Internet. I have tried
System Restore, TCP/IP repair, connected the modem directly to the
computer (took out the router) but it didn't work. I took the PC to
circuit city, they have replaced the ethernet card but still could not
establish connection with their own IP network. (same error message:
"cannot establish connection with IP, please contact network
administrator). I tried to manualy insert the IP and DNS address of
the cable provider but that did not work. I also hooked one of the
laptops via the ethernet cable directly to the modem and it worked
(that means that the ethernet cable is OK).
I also tried via command prompt IPCONFIG /release, /renew as well as
FlushDNS and other tricks that I fould in the HP site but still no IP.
I even tried to load a program called FIX LSP that should restore the
IP by recovering bad registry keys etc. but that did not work as
well.
I even de-installed the ethernet 10/100 card and re-installed it but
that also did not help.

When I click on "repair", it says that it is unable to
renew the TCP/IP address and that I should to contact network
administrator
or ISP.


Plse advise what do I need to do to restore my Internet
connection. Many thanks for your assistance.

HELP HELP HELP.... I am burning the midnight oil here for the last
week.
Thx, Abe

Perhaps the power surge did in the ethernet card.
You can't fix this type of problem with software.

Jim -- Abe has posted in the Original post that the ethernet card was
replaced so the "new" card should be able to get a IP.

Abe -- Have you "considered" getting a wireless adapter for HP. There
are several USB models you can get to "try" to see what is the
problem. Since you have stated a "power surge" occurred and since
then you can not connect from the HP, there might be other "damage"
done the it.

I overlooked that fact in his murky post.

Power surges cause all sorts of problems.

First objective is trying to understand the whole problem without
first breaking the problem down into parts.

For example, if using Windows for information, what does IPCONFIG
report for ethernet status? What does Ping to the router do? What
does Windows system (event) logs report? What does Device Manager
report? Still we don't try to fix anything since changes without
sufficient information may only exponentially complicate the problem.

Move on to now completely remove Windows 'complexity' from the
problem. You bought a computer from a far more responsible
manufacturer. Therefore what do HP comprehensive hardware diagnostics
report?

Ethernet diagnostics will first confirm that motherboard computer
can talk to ethernet card computer and that ethernet computer is
operating properly. Finally, (and unfortunately) we interconnect that
HP ethernet to another computer using same manufacturer's ethernet
card. Last test in that ethernet diagnostic then talk between
ethernet cards. Sometimes cards that work intermittently will only
fail this test after maybe five minutes of data exchange - meaning a
100% defective interface between ethernet computer and router.

Complete diagnostics test all functions, determine which function is
defective, provides information sufficient so that better informed
posters might add further insight (currently better informed posters
can post nothing due to insufficient information), AND eliminates
complications created both by Windows and by fixing things without
first identifying the failure.

Also useful information are those indicator lights. Do lights
illuminate when cable connection is made and extinguish when cable is
disconnected? Having not provided those details, then better informed
posters remain silent. I don't even see router model number or
ethernet interface manufacturer and model number.

Among other possible reasons for failure: that one router port is
damaged; will only connect to 10 Mb ethernet but not 100 Mb ethernet.
Does any other computer connected to that exact same ethernet port
using exact same cable ping to all other computers via that router?

Many more techniques to 'follow the evidence' rather than 'maybe do
this and maybe do that' or shotgunning. Again, your computer is from
a responsible manufacturer. Therefore it has provided comprehensive
hardware diagnostics that better informed posters were recommending.
Use those advantages. Then post technical details - especially all
numbers - so that better informed posters can provide assistance - and
so that you can learn from your experience.

Why do we fix things? Not to save time or money. Both are easier
accomplished by the shop. Number one reason for fixing things - to
learn. Just another reasons why your posts must including information
that will elicit educational replies from the better informed.
