📅 Updated: March 2026  |  ⏱ 5 min read  |  ✅ Tested on Windows 11 24H2

If your network adapter is missing in Windows 11, your PC cannot detect WiFi or Ethernet connections. This often happens after a Windows update, driver corruption, or accidental setting change — but the adapter is rarely truly gone. In most cases, it just needs to be re-enabled, updated, or reset.

❌
The Problem: Network adapter not showing in Device Manager, Network Settings, or the taskbar WiFi icon has disappeared.
✅
Good News: This problem is fixable in most cases without reinstalling Windows. Follow the steps below in order.

Why Is the Network Adapter Missing in Windows 11?

There are several common reasons this happens:

🔧 Corrupted or outdated network driver
🔄 Windows Update conflict
🙈 Adapter hidden in Device Manager
🚫 Adapter manually disabled
💾 BIOS/UEFI network setting disabled
🌐 TCP/IP stack corruption
⚠️
Tip: Before trying any fix below, note whether the problem appeared after a Windows Update. If yes, start with Fix 4 (Update Driver) or Fix 5 (Reinstall Driver).

Fix 1 Restart Your Computer

The simplest fix first. A basic restart reloads all system drivers and clears temporary glitches that may be hiding the adapter.

  1. 1Click the Start button (Windows icon)
  2. 2Click the Power icon
  3. 3Select Restart (not Shut Down)
  4. 4After reboot, check Device Manager → Network Adapters
💡 Pro Tip: Always choose Restart, not Shut Down + Power On. A fresh restart fully reloads drivers; a cold boot from Shut Down can use Fast Startup cache.
Fix 2 Show Hidden Devices in Device Manager

The adapter may be present but hidden. Device Manager hides disconnected devices by default.

  1. 1Press Win + X → select Device Manager
  2. 2In the top menu, click View
  3. 3Select Show Hidden Devices
  4. 4Expand the Network Adapters section
  5. 5If you see an adapter with a grey/faded icon, it is hidden
  6. 6Right-click it → select Enable Device
✅
If your adapter appears greyed out and becomes active after enabling, your problem is solved.
Fix 3 Enable the Network Adapter

If the adapter is visible but has a small arrow (↓) or exclamation mark icon, it may be disabled.

  1. 1Open Device Manager (Win + X → Device Manager)
  2. 2Expand Network Adapters
  3. 3Right-click your network adapter
  4. 4If you see Enable Device, click it
  5. 5Wait a few seconds and check if network returns
💡 Pro Tip: You can also enable the adapter from Settings → Network & Internet → Advanced Network Settings → Network Adapters.
Fix 4 Update Network Driver

An outdated or incompatible driver — especially after a Windows Update — is one of the most common causes of a missing adapter.

  1. 1Open Device Manager
  2. 2Expand Network Adapters
  3. 3Right-click your adapter → select Update Driver
  4. 4Choose Search automatically for drivers
  5. 5Let Windows install the latest compatible driver
  6. 6Restart your PC when prompted
⚠️
Better option: Visit your PC manufacturer’s website (Dell, HP, ASUS, Lenovo) and download the latest network/WiFi driver directly. Manufacturer drivers are often more up-to-date.
Fix 5 Reinstall Network Driver

If the driver is corrupted, updating may not be enough. A clean reinstall is needed.

  1. 1Open Device Manager
  2. 2Expand Network Adapters
  3. 3Right-click the adapter → Uninstall Device
  4. 4Check “Delete the driver software for this device” → click Uninstall
  5. 5Click Action → Scan for hardware changes
  6. 6Windows will automatically reinstall the default driver → Restart PC
💡 Pro Tip: Download your manufacturer’s driver beforehand using another device or mobile hotspot, so you can install it immediately if Windows does not auto-reinstall.
Fix 6 Run Network Adapter Troubleshooter

Windows 11 has a built-in troubleshooter that can detect and automatically fix many network adapter problems.

  1. 1Open Settings (Win + I)
  2. 2Go to System → Troubleshoot
  3. 3Click Other Troubleshooters
  4. 4Find Network Adapter → click Run
  5. 5Follow the on-screen instructions and apply any fixes suggested
Fix 7 Reset TCP/IP Stack via Command Prompt

A corrupted TCP/IP stack or Winsock catalog can cause the adapter to appear missing. This fix resets core networking components.

  1. 1Press Win + S → type cmd
  2. 2Right-click Command Prompt → Run as administrator
  3. 3Type each command below and press Enter after each
Command Prompt (Admin)
netsh int ip reset
netsh winsock reset
ipconfig /release
ipconfig /flushdns
ipconfig /renew
  1. 4After all commands complete, restart your PC
💡 Pro Tip: This fix is especially effective if your adapter is visible in Device Manager but you still have no internet connection.
Fix 8 Check BIOS/UEFI Settings

On some systems, the network adapter can be disabled directly in the BIOS firmware. This is rare but happens after a BIOS reset.

  1. 1Restart your PC and press F2, F10, F12, or Del to enter BIOS
  2. 2Navigate to Advanced or Integrated Peripherals settings
  3. 3Look for “Onboard LAN”, “Wireless LAN”, or “Network Controller”
  4. 4Make sure these are set to Enabled
  5. 5Save changes and exit BIOS (F10 in most systems) → Boot into Windows
⚠️
Caution: Only change BIOS settings you recognize. Incorrect BIOS changes can prevent Windows from starting.
Fix 9 Reset Network Settings (Last Resort)

If nothing else has worked, a full network reset will remove all network adapters and reinstall them, restoring all networking components to factory defaults.

  1. 1Open Settings (Win + I)
  2. 2Go to Network & Internet
  3. 3Scroll down → click Advanced Network Settings
  4. 4Click Network Reset → Reset Now and confirm
  5. 5Your PC will restart automatically
⚠️
Note: Network Reset will remove saved WiFi passwords and VPN configurations. You will need to reconnect to your WiFi networks after the reset. It does not delete your personal files.

❓ Frequently Asked Questions

Why did my network adapter suddenly disappear in Windows 11?
This usually happens after a Windows Update that installs an incompatible driver, or when the adapter gets accidentally disabled. Rarely, a BIOS reset or hardware failure can also cause it.
How do I get my network adapter back without internet access?
Use Device Manager (Win + X → Device Manager). From there, you can show hidden devices, enable, update, or reinstall the driver — all without needing an internet connection. For driver downloads, use a smartphone USB hotspot.
Will resetting network settings delete my files?
No. Network Reset only removes and reinstalls network adapters and resets networking components like TCP/IP and Winsock. Your personal files, photos, documents, and apps are not affected.
My network adapter is visible but showing a yellow exclamation mark. What does that mean?
A yellow exclamation mark (!) means the driver has an error. Right-click the adapter → Properties → check the error code under Device Status. Then update or reinstall the driver using Fix 4 or Fix 5 above.
Is it safe to reset the TCP/IP stack?
Yes. The netsh commands only reset network configuration settings and do not affect your files or Windows installation. A restart is needed afterwards.

✅ Conclusion

If the network adapter is missing in Windows 11, the problem is almost always related to a disabled device, a corrupted driver, or a networking configuration error. Start with the easiest fixes (Restart, Show Hidden Devices, Enable Adapter) before moving to more advanced options like TCP/IP Reset or BIOS settings.

If none of the fixes above work, your network adapter hardware may have a physical fault. In that case, a USB WiFi adapter is a quick and affordable solution while you arrange a hardware check.
