network adapter driver problem

When encountering the problem of "Windows could not find a driver for your network adapter", it is usually caused by the driver or system settings rather than hardware damage. You can solve it as follows: 1. Use the device manager to update or uninstall the network card driver and restart; 2. Go to the motherboard official website or use a third-party tool to manually download and install the network card driver; 3. Check the USB or PCIe interface, BIOS settings and power management options; 4. Run sfc /scannow to repair the system files or use DDU to thoroughly clean the old driver and then reinstall it.

How to fix \

If you encounter the problem of "Windows could not find a driver for your network adapter", it usually means that the system cannot recognize the network card device, resulting in the network connection failure. When this prompt appears, in most cases, it is not that the hardware is broken, but that the driver problem or the system settings are incorrect. Below are some common and practical solutions that can be troubleshooted and fixed step by step.

How to fix

1. Update drivers using Device Manager

This is the most direct way. In many cases, the problem is simply because the driver is not installed correctly or expired.

  • Open Device Manager (you can search in the Start menu)
  • Find the "Network Adapter" item and click to see if there are any devices with yellow exclamation marks.
  • Right-click the problematic network card device and select "Update Driver"
  • Select "Automatically search for updated drivers"

If the system prompts that the new driver cannot be found, you can also try "Uninstall the device", then restart the computer, and let the system re-detect and install.

How to fix

2. Manually download and install the network card driver

Sometimes the driver library that comes with the system may not contain the corresponding models of your motherboard or network card, so you need to manually download it on the official website.

  • Determine your network card model (can be found through BIOS and motherboard brand model)
  • Go to the official website of motherboard manufacturers, such as Asus, Gigabyte, MSI, etc., and find the support page for the corresponding model
  • Download the latest network driver (LAN or Ethernet driver) and run and install it

If you don't know the specific model, you can also use some third-party tools, such as Driver Booster or Snappy Driver Installer to help you identify and download the driver.

How to fix

3. Check whether the PCIe/USB interface is working normally (for external network cards)

If you are using an external USB network card or wireless network card, it may be due to insufficient power supply or poor contact.

  • Try to plug in with a USB port, especially don't plug it in the hub all the time
  • If it is a desktop computer, you can also try changing a PCIe slot (if it is a separate network card)
  • Check whether the integrated network card is disabled in the BIOS (some notebooks can turn off the built-in network card)

Sometimes the power management settings will also cause the network card to be powered off and hibernate. You can enter the network card properties in the device manager and uncheck "Allow the computer to turn off this device to save power" in the "Power Management" tab.


4. System file corruption or driver conflict

If none of the above methods work, it may be that there is an error in the system file or that there is a residual driver.

  • Run command prompt (administrator permissions) to enter:

     sfc /scannow

    This command scans the system files and tries to fix the damaged parts.

  • You can also try using "System Restore" to return to the time you were able to access the Internet before

  • If you suspect that it is a driver conflict, you can use DDU (Display Driver Uninstaller) similar tool to clean up all network card drivers and then reinstall them.


Basically these common ways of dealing with it. Although the problem seems scary, most cases can be solved by updating the driver or manually installing it. The key is to confirm whether the system identification problem or the hardware itself is faulty.
