Can't connect to Internet, NIC seems to work fine

[R. J. Salvi]

Specs:
NIC: Intel Pro1000 MT
Drivers: latest Intel (10.3)
Mobo: ASUS P5LP-LE (HP box) with latest BIOS
OS's: MCE 2005 SP2, XP Pro SP2, XP Pro 64bit SP2...all fresh installs

Symptom: tries to open web page -- "opening web page" in status bar -- then
page times out after a few minutes

What works: ping & tracert by both name and IP address and Intel's NIC
diagnostics shows no problems

What's been tried:
- different cables (CAT5 and CAT5e)
- bypass router and wire NIC directly to cable modem
- different router ports
- different PCI slots for NIC

What's not been tried:
- NIC in different PC
- check MTU settings in registry

Any suggestions are appreciated. Thx.

Hi

In General, you can debug the Network Settings of a computer by following
these steps.
Step One. Check the Network parameters in the Computer's Device Manager.
Make sure that the Network Card drivers are installed correctly; i.e. there
is No IRQ conflict, and No Ghost installation.

Step Two Verify Basic network setting in the OS:

every thing looks good but functionally it does not work.
Step Three. Check (and repair if necessary) the Socket Layers, Winsock, and
or refresh the TCP/IP Stack. http://www.ezlan.net/clean#refreshnet
If need to Reinstall; Log to this page it have a lot of links to
instructions for Windows Network

Thanks, Jack. Unfortunately, the problem persists.

Reset TCP/IP stack, ran Winsock fix (though I'm not sure if XP Pro 64bit and
32bit are similar), set static IP, flushed DNS cache, etc.

I have a new card on the way based on the Reaktek chip, so we'll see what
happens.

Is the IP address assigned to the card correct? I'm having a very similar
problem. I have a Linksys router that is NATing two computers in my home. One
computer works fine. The other one worked fine when I first installed Windows
XP but a couple of weeks later I lost internet access and the IP is no longer
in the "public" range. Even when I manually config everything I still can't
connect. I purchased a Wn XP home Edition upgrade....I'm wondering if that
has something to do with it. I've installed on two seperate hard drives and
have experienced the same problem.

IP, DNS, Gateway...all entries are correct. It wouldn't work with DHCP
enabled either. I've come to the conclusion that one of two things is/are
the issue:

*either the card is faulty and it cannot be determined by Intel's
diagnostics, or
*there's an issue between this card/chip and the motherboard BIOS

It was tried on fresh installs of three different OSs and the results were
exactly the same. What I haven't done yet, is install the card in another
machine. Fwiw...the card is an Intel PWLA8390MT. Thx.

The card is bad. Thanks all for the help.
