How to detect faulty network card driver?

Detecting a faulty network card driver can be a tricky task, as it can be difficult to determine whether the problem lies with the network card itself or the driver that controls it. However, there are a few steps that can be taken to help diagnose the issue and resolve it.

1. Check the Network Card Status
The first step in diagnosing a faulty network card driver is to check the status of the card itself. You can do this by opening up the Device Manager and looking for the network card under the ‘Network Adapters’ section. If the card is not listed, it may indicate a hardware issue and you should check the hardware documentation or contact the manufacturer for further assistance. If the card is listed, check to see if it has an exclamation mark or an “x” next to it, which indicates that the device has encountered a problem and requires further investigation.

2. Update/Reinstall Drivers
If the card has an exclamation mark or an “x” next to it in the Device Manager, it could mean that the driver is out of date or corrupted. To fix this issue, you should try to update the driver. If the issue persists, you may need to uninstall and reinstall the driver manually. To do so, go to the manufacturer’s website and download the latest version of the driver. Once downloaded, open the folder and double-click the executable file to begin the installation. Follow the on-screen instructions to complete the installation.

3. Use System Restore
If the driver update or reinstall did not solve the issue, you can try performing a system restore to roll back the system to an earlier time when the network card was functioning properly. To do this, open the “Run” command by pressing the Windows key + R and then typing “rstrui”. This will open the System Restore window. Select the “choose different restore points” option and select the most recent restore point before the issue occurred.

4. Check for Viruses/Malware
It is also possible that your network card driver is being affected by viruses or malware. To check for this, you should scan your system using an updated antivirus program. If any malicious programs are found, follow the recommended steps to remove them.

5. Contact the Manufacturer
If none of the above steps have helped to resolve the issue, you should contact the manufacturer of the network card. They may be able to provide further advice on how to troubleshoot or replace the driver or card.

By following these steps, you should be able to diagnose any issues with your network card driver and fix them. It is important to remember that if you are unsure of any of these steps, you should contact the manufacturer of the network card for further assistance. Additionally, ensure that your computer is always running the latest version of the network card driver and its associated software to prevent any further issues from occurring.
