    First a little history on my sons computer, it was purchased from a friend of his who made the computer, i came to find out he pirated a copy of windows when he made the comp. ( a couple years back) recently the comp. became infected and he could not access his files so i got him a genuine copy of windows xp so he could reformat his computer (crash and start over) so prior to doing this everything was working fine. So since this is not a manufactured computer hoe do i get the necessary software to get the card or driver working so it will reconize the ethernet cable. thankyou to the people who have responded, if you have a soulution please try to keep it in simple terms i am no computer guiness. Thankyou so much

    Check if your Ethernet cable is properly connected. Were you use the right installer for the ethernet? Is it really a modem port? or it is a LAN port?

If your son' s computer has a LAN port, then install the LAN driver. LAN port is different from modem. Modem is used for dial-up connection while LAN uses broadband or dsl connection. If you do not know where or how to find the LAN driver, post the manufacturer and model name of your LAN or the motherboard. You can also find it by right clicking the My Computer icon->Manage->Device Manager. On the right side, Expand the Network Adapter. You will then find the software that you are going to reinstall. Another thing is to try to update the driver if it works or not. Here are the steps :

  1. Right click My Computer icon.
  2. Click Manage
  3. A box will appear (Computer Management), Click Device Manager
  4. On the right side, Click and expand Network Adapters
  5. Right click the software, click update driver.
  6. Wait 'til it finds the necessary software.
  7. If it does, then your finished installing the Network Adapter driver. If it says it cannot find the necessary software, you have to manually install it.
  8. IF NOT yet installed, copy the Network Adapter software and paste it in google to find your Network Adapter installer.

It is likely that you have not installed the Network card driver.

Right click on My Computer and choose properties. Select the Hardware tab and click on the Device manager button.

In the list you will probably see at least one listing of Unknown device. If you do not have the driver already, you should be able to go to the website of the computer maker to find a driver.

Find the drive and install it.

If you need additional help, let me know.

Please provide the make (Dell, HP, etc) and model (Inspiron 6000, or whatever).

    Thanks for the additional information. It is typical for Windows to recognize major name brands, but there are a large number of manufacturers of ethernet cards and Windows can not keep up with all of them.

    I propose 2 solutions.

    1. The easiest solution is to power down the computer, unplug the power cord, open the computer, unscrew the holding screw on the ethernet card and buy a replacement at a local computer store. They can be purchased for as little as $14 so don't pay much more than that without some shopping around. The new card will come with the driver or instructions on what driver to select.

    2. Look at the card you took out to see if you can identify the manufacturer. If you can, do a Google search on the brand and any ID numbers on the card. Most cards have a number of ID numbers in various places so don't give up. Eventually you will find the manufacturer and then the maker's website for a driver.

    One other option to consider is that the ethernet port is integrated with the mother board. In a case like that, you will need to enter the BIOS when the very first display is on the screen (enter Setup).

    Look for a menu choice indicating integrated devices and find anything with network or NIC and disable it. Then buy a new card.

    If you are determined not to buy a card, you can search the Internet for the make and model of the mother board and possibly find the network driver file.

    Let me know how it goes.

Please ensure the following:

1. Make sure you use the LAN port.
2. Ensure the cable is in good condition. Try using new cable.
3. Ensure you installed proper network card driver.
4. Ensure the network card using correct link speed (100Mbps).
5. Try switching the link speed to Auto, if you're not sure.

These are the basics. If possible, try installing the latest firmware for your network card. Normally, downloadable from the manufacture's site.

Network cable not properly plugged in or may be broken

which OS do you have? XP, Vista, 7, etc. you must have a wireless adapter in your PC to use wireless and it must be enabled.
if not wireless, then you must have an ethernet slot with cable(CAT5) inserted from internet modem/router. if you have a laptop then you have wireless available. there is a key on keyboard to turn wireless on. you have to have your Network assigned to the wireless internet provider too. if you have cable(cat5) connected to a modem or router/modem connection, and you see an ethernet icon in your lower right corner window(looks like a little computer display), then you have an ethernet connection. if not then either the cable is bad or the modem/router is not producing a connection to pc. thats alot i know but i have little knowledge about your internet connection on your pc. you have not given that to me to use

I cant connect to my internet using a ethernet cable, it say limited or no connection yet after going through this with virgin media for an hour turns out the problem is to do with me not them, please

if you were able to connect earlier on this computer and if you can connect on another system/ computer using the same ethernet cable and virgin media connection as of now it does mean that the issue is computer specific so you can try a system restore thru start>>programs>>accessories>>system tools>> system restore and restore the system to a earlier time when you were sure that internet connection worked. you can also try forcing ip and dns settings which Virgin media can provide. also you can try changing the speed and duplex settings to force 10mb half duplex and see if it works. Good luck

Ethernet controller and USB are missing on XP

Yes, the device-drivers can be downloaded from the Internet, to one computer, and then burned onto a CD-writable, or written to a USB memory-stick, and then the files can be physically moved to the other computer.

But, "which" device-drivers is completely dependent on which computer that you have. Some motherboards have "integrated" network-adapters and "integrated" USB-ports.

Easiest solution is to take an add-in PCI network-adapter card, and install it, and connect the Ethernet cable to its socket.
Hopefully, Windows will recognize that card, and automatically load the correct device-drivers from the C: drive, i.e., without Internet access.
Or, if you buy an add-in card, it may come with a CD-ROM that contains the device-driver.

Once the device-drivers have been installed, you will have Internet connectivity. Access:
and click "Custom" scan, and then click "Optional Hardware".
Windows Update should find the device-drivers for your motherboard, and install them. Then, you can remove the add-in card, and connect the Ethernet cable to the "on-mother-board" network socket.

I reinstalled Windows XP to my computer and now i cant get the internet. There is a yellow question mark and exlmation point next to Ethernet Controller and it has a code 28 error.

You should have had 2 cds that came with your computer. The 2nd one has all the drivers on it. Install the drivers and your problem will go away.

Very possible you don't have the correct ethernet driver. Try looking up the driver off the manufacturer of you computers website. It will be listed as a "network driver". Good luck!

Local Connection 2 Unplugged

If you have a spare cat5 / ethernet cable that you know to be good just swap it.

Also at the router end plug it into a different port (one you know is working)

That's about all there is to it
