I recently decided to start fresh and I reformatted my computer with the recover discs. The recover discs were junk and i ended up having to just use a regular copy of windows xp. Once i got it installed i noticed in my device manager that there were a few devices not recognized and none of those devices were a network adaptor. So i hooked up my comp via USB and was able to update my computer to service pack 2 which then recognized all my devices but still no ethernet adaptor. Now it isnt a problem at the moment but I would really like to be able to hook up to the internet via my router at some point in the future. Also i have tried installing a PCI ethernet card and once again it did not recognize it. Any ideas about how to get my computer to recognize the built in ethernet port?

Can't you download drivers from the manufacturer's website?

XP is very good at detecting devices, network adapters being no exception.
What I suspect, assuming that your computer has a built-in network adapter,
is that it is one of the "Unknown" devices listed in Hardware Manager.
XP may not have recognized it as being a network adapter.

You said that you downloaded the "original drivers". Does that mean you
downloaded the -manufacturer's latest- drivers ? How did you install
the driver ? Did the download have an install program or was it just the
driver files with a ???.INF file among them ? If it is just a group of
6 or 8 files you will need to go into Device Manager and "update" the
driver (read "install") them manually by navigating to that ???.INF file.

Sometimes network adapter chips built into a motherboard can be turned off
in the BIOS. If so, this would prevent XP from seeing the device at all.
Try going into the BIOS to see if this is what happened and turn it back on
if this is the case.

The only way XP would not recognize a network adapter plug-in card is if
the card was bad. Otherwise it will show up in the Device Manager, recognized
as a network adapter or not. Some new device should show up there.
Check again. Maybe there is an unidentified device listsed when that card
is plugged in. Don't expect XP to have the driver for any plug-in card,
much less a built-in device. Typically, there will be an install CD for a
network card or networking built-in device. What happened when you ran the
install CD for the plug-in card ?

BTW, what is the make and model number of your computer ? I'll take a look
at the manufacturer's site and get back to you.

its a hp pavillion a350y Ill recheck the device manager to see it there are any devices not being recognized or that i think dont belong. As for getting the original drivers I downloaded them from HP.com they were the originals from when i got my computer. They came in a .exe file as for being shut off in the BIOS you might have to tell me how to check that altho i am ok with computer I have never done that. Thanks for the help thus far tho I really appreciate it.

If they were in an exe file they should have installed automatically.

This is one of the reasons why the restore cd is better than using a generic installation.

What do you mean "they were junk"?

If you booted with the correct restore cd it should have given you the option to restore XP.

Now that I think about what I said before, I think it is unlikely that
the networking device is turned off in the BIOS and therefore can not
be seen in the Device Manager.

I agree with Enthusiast in that the device driver CD that came with your
computer should have the proper drivers for your built-in network port.
I have done many OS installs using a generic (OEM) XP install disc with
the computer manufacturer's driver CD to save time rather than having to
navigate the manufacturer's web site and download the files.

When you insert the disc it will probably auto-start. You will probably
have to navigate through it's menus to load the driver for networking.
Don't be concerned about mistakenly loading the wrong driver because XP
will only use the particular driver that matches the device that currently
has no driver (the one that has a yellow icon with a question mark in it
listed in the Device Manager.

Try using the driver CD again - this is the easiest way to install
the driver files. I navigated to the HP web page for your model and found
the networking drivers titled "Fall 2003 Original Network Adapter Collection.
To use these you must know the brand name of the network chip in your
machine. Check the Device Manager again - its got to be there ! Its
going to be listed under either "Network adapter" or "Other".
Its going to be one of nforce, Realtek, SIS or VIA.

If the icon next to the device is yellow it means there is no driver for it
and it needs one. If its red it means the device driver installed for it
is not right. Anyhow, check for either (or both) the two headings for a
network device. It will be listed under one of those.

(Start > Control Panel > double-click System > Hardware Tab > Device Manger
button. Click the plus sign (+) to expand the group and find out what is listed
there and what the icon looks like. If you are using this computer to access
this board then there is another network adapter being used. Ignore its
listing. Your non-working adapter should be listed there, too. Note
the name/number of that built-in networking device.

The driver CD may simply copy the driver to your hard disk and then leave it
up to you to install it. This is really easy. Once you know the name of the
networking chip (nforce, Realtek, SIS or VIA) you can right-click on its
listing in the Device Manager and choose "Update Driver". Its looking for
you to navigate to the .INF file in one of the 4 directories created under
C:\HP when you ran the executible download file from the HP web site.

To sum this all up, there are 2 ways to install the driver:
1) run the HP drivers disc which will create a directory C:\HP\... and then
you use the Device manager to install the driver, or,
2) download the exe file from the HP site and run it, which will create the
directory C:\HP\... and then use Device Manager to install the driver.

You can get this worked out. Give yourself some time and take it step by step.

One other suggestion is to download Everest Home Edition from oldversion.com
(oldversion.com because Everest is no longer offered as freeware by Lavalys, its author, and you can still get version 1.51 from oldversion that still has full functionality)

It will tell you about all hardware and software on your computer and provide the proper links for updates (sometimes).

Worth a try and a great ap to have anyway:

Get version 1.51 which has the Software listing capability which successive versions have deleted.

Download here:

The restore discs were messed up or something so i could not use them i would be force to abort the install when i would get to 40% or so and i would start getting error messages.
