Why Network Adapter Disappeared from Device Manager Happens

A Network Adapter Disappeared from Device Manager is a common issue where the network adapter (Ethernet or Wi-Fi) is no longer visible in Device Manager, preventing internet access. This can happen suddenly after a Windows update, driver conflict, or hardware issue. For official Microsoft documentation, refer to the Microsoft network adapter troubleshooting guide.

When a Network Adapter Disappeared from Device Manager occurs, the system either does not detect the adapter or hides it due to driver or configuration issues. This problem is similar to other hardware detection issues like USB Device Not Recognized and GPU Not Detected. Common triggers include outdated or corrupted drivers, Windows updates that break compatibility, BIOS/UEFI settings disabling the adapter, power surges or static discharge, physical hardware failure, and incorrect power management settings.

Before diving into fixes, check if the network adapter appears in the BIOS/UEFI settings. If it is not detected there, the issue may be hardware-related. For a broader overview of Windows issues, see our Windows 11 Troubleshooting Hub.

⚠️ Warning: If a Network Adapter Disappeared from Device Manager after a Windows update, the update may have installed an incompatible driver. Rolling back or uninstalling the update can resolve the issue.

Open Device Manager.
Click Action in the top menu and select “Scan for hardware changes”.
Wait for the scan to complete.
Check if the network adapter reappears under Network adapters.
If it appears, right-click and select Enable device.

💡 Quick Tip: You can also run the scan from Command Prompt: pnputil /scan-devices.

3. Update or Reinstall Network Adapter Driver
