Fixing this issue is important to restore your network connectivity and ensure smooth functioning of your device. Fortunately, there are several simple solutions you can try on your own before seeking professional help.

In this article, we will guide you through easy and effective steps to resolve the “Windows 11 Did Not Detect Installed Network Adapter” error. Each step is explained clearly so even beginners can follow along.

By the end, you should be able to get your network adapter recognized and working again without any hassle.

Quick Note: Preliminary Checks

Before diving into the troubleshooting steps, make sure of the following:

  • Your network adapter is physically connected properly. If you are using a desktop, check the cable and adapter seating. For laptops, ensure the wireless adapter is enabled.
  • Restart your computer. Sometimes a simple reboot fixes temporary glitches.
  • Check if Airplane Mode is turned off. This disables all wireless connections.
  • Ensure Windows 11 is up to date. Updates often include fixes for hardware detection issues.

Step 1: Run the Network Troubleshooter

Windows 11 includes a built-in troubleshooter designed to identify and fix common network problems automatically. Running it is a quick way to detect the issue.

  1. Click the Start button and select Settings (the gear icon).
  2. Go to System > Troubleshoot > Other troubleshooters.
  3. Find Network Adapter in the list and click Run.
  4. Follow the on-screen instructions to complete the troubleshooting process.

This step helps by scanning your network devices and attempting automatic repairs or resetting network settings if needed.

Step 2: Check Device Manager for Network Adapter Status

The Device Manager shows all hardware installed on your computer. Sometimes, the network adapter may be disabled or have driver issues.

  1. Press Windows + X and select Device Manager.
  2. Expand the Network adapters section.
  3. Look for your network adapter. If you see a yellow exclamation mark, it indicates a problem.
  4. If the adapter is missing, click on View > Show hidden devices to see if it appears.
  5. If the adapter is disabled, right-click it and choose Enable device.

Checking Device Manager allows you to identify driver or hardware recognition issues, which are common causes of this error.

Step 3: Update or Reinstall Network Adapter Drivers

Outdated or corrupted drivers can prevent Windows from detecting your network adapter. Updating or reinstalling the drivers often fixes this problem.

  1. Open Device Manager again.
  2. Right-click your network adapter and select Update driver.
  3. Choose Search automatically for drivers. Windows will find and install any available updates.
  4. If no update is found or the issue persists, right-click the adapter and select Uninstall device.
  5. Restart your computer. Windows will try to reinstall the driver automatically.

Reinstalling drivers clears any corruption or conflicts that might cause detection issues.

Step 4: Reset Network Settings

Resetting network settings restores all network components to their default state. This can fix misconfigurations affecting adapter detection.

  1. Open Settings and go to Network & internet.
  2. Scroll down and click Advanced network settings.
  3. Under More settings, select Network reset.
  4. Click Reset now and confirm.
  5. Your PC will restart and reset all network adapters.

This step is important because it removes all custom network configurations that might block the adapter from being detected.

Step 5: Check BIOS/UEFI Settings

Sometimes, the network adapter might be disabled from the BIOS or UEFI firmware. Enabling it there ensures Windows can detect it properly.

  1. Restart your computer and enter BIOS/UEFI settings (usually by pressing F2, Delete, or Esc during boot).
  2. Look for settings related to Integrated Peripherals or Onboard Devices.
  3. Ensure the network adapter or LAN controller is Enabled.
  4. Save changes and exit BIOS/UEFI.

Enabling the network adapter at the firmware level is critical if it has been disabled accidentally or by default.

Alternative Method: Use Command Prompt to Reset Network Components

If the above steps do not work, you can manually reset network components using Command Prompt.

  1. Press Windows + S, type cmd, right-click Command Prompt, and select Run as administrator.
  2. Type the following commands, pressing Enter after each:
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

These commands reset network protocols and refresh IP settings, which can fix adapter detection issues caused by software corruption.

FAQs

Why does Windows 11 not detect my network adapter?

Common reasons include outdated or missing drivers, disabled adapter in Device Manager or BIOS, corrupted network settings, or hardware faults.

Can I fix this issue without reinstalling Windows?

Yes, most cases can be fixed by troubleshooting drivers, resetting network settings, or enabling the adapter in BIOS.
