How to Reinstall Windows XP Ethernet Controllers

In a computer operating system, drivers - also known as controllers - allow the computer's central processing unit (CPU) to access and control all of the devices attached to the computer, including mice and other pointing devices, keyboards, modems and sound cards.

If the controllers for the ethernet/network card become corrupted, or if an attempted driver upgrade fails, they may need to be reinstalled. Luckily, reinstalling drivers in Windows XP is a relatively simply task.

Step

Download the correct driver file for your network card. This can normally be found by visiting the "Drivers and downloads" page at your computer manufacturer's website. (Also, see the Resources section.) Take note of where the file is saved.

Step

Right-click on My Computer, and select "Manage." Select "Device Manager" on the left of the Computer Management window.

Step

Click the plus sign next to Network adapters to expand the list. The adapter that needs to be installed should have a yellow question mark next to it.

Step

Right-click on the necessary adapter and select "Update driver."

Step

Select "No, not this time" in the Hardware Update Wizard and click Next.

Step

Select "Install from a list or specific location" and click Next.

Step

Click the Browse button and navigate to the folder where you saved the necessary driver file. Select the driver file and click OK.

Step

Click install and allow the wizard to install the driver file. Close the wizard and the computer management window.

Step

Reboot the computer to update the registry and complete the install.
