WiFi Not Working After Windows Update? Here Are 12 Fixes

You installed a Windows update, restarted your PC, and now your WiFi is gone. No internet connection, no network adapter showing, or the WiFi icon has completely disappeared from the taskbar.

This is one of the most common problems Windows users face after an update. The good news is it is almost always fixable without reinstalling Windows or buying new hardware. I have personally tested every method in this guide on real hardware, and at least one of them will work for you.

Let me walk you through all the fixes, starting from the simplest ones.

Why Does WiFi Stop Working After a Windows Update?

Before jumping into fixes, it helps to know what actually causes the problem. Windows updates sometimes break WiFi for a few specific reasons:

• Driver compatibility issues – The update replaces your WiFi driver with a generic one that does not fully support your adapter.
• Corrupted network settings – Update files can corrupt the TCP/IP stack or Winsock settings that WiFi depends on.
• Disabled network adapter – Some updates reset the network adapter to a disabled state automatically.
• Broken Windows services – The WLAN AutoConfig service, which manages all WiFi connections, can stop running after an update.
• Update bugs – Microsoft occasionally releases updates with known bugs that affect specific WiFi chipsets (Intel, Realtek, Qualcomm).

Fix 1: Disable and Re-enable the WiFi Adapter

This is the fastest thing to try and it fixes the problem more often than you would expect. A quick disable and re-enable forces Windows to reinitialize the adapter and re-detect it properly.

1. Press Windows + X and click Device Manager.
2. Expand the Network Adapters section.
3. Right-click your WiFi adapter (it will say something like “Intel Wireless” or “Realtek WiFi”).
4. Click Disable device, then wait 5 seconds.
5. Right-click it again and click Enable device.

After enabling it, check if the WiFi icon returns to the taskbar. If yes, connect to your network and you are done. If not, move to the next fix.

Fix 2: Check the WLAN AutoConfig Service

WLAN AutoConfig is the Windows service that handles all WiFi connections. If this service is stopped or set to Manual instead of Automatic, your WiFi will not work even if the adapter is fine.

1. Press Windows + R, type services.msc, and press Enter.
2. Scroll down and find WLAN AutoConfig.
3. Double-click it to open its properties.
4. Set the Startup type to Automatic.
5. Click Start if the service is currently stopped.
6. Click Apply, then OK.

Fix 3: Reinstall the WiFi Driver

If Windows installed a broken or incompatible driver during the update, reinstalling it clears out the bad installation and lets Windows find the right one.

1. Open Device Manager (Windows + X).
2. Expand Network Adapters.
3. Right-click your WiFi adapter and click Uninstall device.
4. Check the box that says Delete the driver software for this device.
5. Click Uninstall.
6. Once removed, click Action in the top menu, then Scan for hardware changes.

Fix 4: Roll Back or Update the WiFi Driver

If the update replaced a working driver with a newer but broken one, you can roll it back to the previous version. Alternatively, if you were on an old driver, updating it manually can also solve the problem.

To roll back the driver:

1. Open Device Manager.
2. Right-click your WiFi adapter and click Properties.
3. Go to the Driver tab.
4. Click Roll Back Driver if the button is available.
5. Select the reason and click Yes.

To update the driver:

1. Right-click your WiFi adapter in Device Manager.
2. Click Update driver.
3. Select Search automatically for drivers.
4. Let Windows find and install the best available driver.

Fix 5: Disable Power Saving Mode on the WiFi Adapter

Windows updates sometimes reset the power management settings on your network adapter. If Windows is putting your WiFi adapter to sleep to save power, your connection will drop or disappear entirely.

1. Open Device Manager.
2. Right-click your WiFi adapter and click Properties.
3. Click the Power Management tab.
4. Uncheck Allow the computer to turn off this device to save power.
5. Click OK.

Fix 6: Run the Windows Network Troubleshooter

The built-in troubleshooter can automatically detect and fix common issues like missing IP addresses, reset adapters, and DNS problems within seconds.

On Windows 11:

1. Go to Settings (Windows + I).
2. Click System, then Troubleshoot.
3. Click Other troubleshooters.
4. Click Run next to Internet Connections.
5. Follow the on-screen steps.

On Windows 10:

1. Go to Settings and click Update and Security.
2. Click Troubleshoot, then Additional troubleshooters.
3. Click Internet Connections and run the troubleshooter.

Fix 7: Reset Winsock and TCP/IP Stack

This is one of the most effective fixes when Windows updates corrupt the network stack. Winsock is the interface that programs use to communicate over a network. If it gets corrupted, nothing can connect even if your adapter is working fine.

1. Click the Start button, search for cmd.
2. Right-click Command Prompt and click Run as administrator.
3. Type each command below and press Enter after each one:

netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /flushdns
ipconfig /renew

4. Restart your PC after all commands complete.

Fix 8: Uninstall the Problematic Windows Update

If your WiFi was working perfectly before a specific update and stopped immediately after, you can remove that update to get back to a working state.

1. Press Windows + I to open Settings.
2. Go to Windows Update and click Update history.
3. Scroll down and click Uninstall updates.
4. Find the most recent update (check the date it was installed).
5. Click it and select Uninstall.
6. Restart your PC.

Fix 9: Reset Network Settings

A full network reset removes all network adapters and resets all network components back to their default settings. Think of it as a clean slate for your entire network setup.

1. Go to Settings (Windows + I).
2. Click Network and internet.
3. Scroll down and click Advanced network settings.
4. Click Network reset.
5. Click Reset now and confirm.

Your PC will restart automatically. All saved WiFi passwords will be erased, so have them ready to re-enter.

Fix 10: Download and Install the Latest WiFi Driver Manually

If Windows Update is not finding the right driver, go directly to your manufacturer’s website and download the latest one for your specific laptop or adapter model.

1. Find your laptop model (check the sticker on the bottom or press Windows + Pause/Break).
2. Visit your manufacturer’s support page:
   • Dell: dell.com/support
   • HP: support.hp.com
   • Lenovo: support.lenovo.com
   • ASUS: asus.com/support
   • Acer: acer.com/support
   • MSI: msi.com/support
3. Search for your model and download the latest WiFi or Wireless LAN driver.
4. Run the installer and follow the instructions.
5. Restart your PC.

Fix 11: Power Flush Your PC

This sounds too simple but it works, especially on laptops. A power flush fully drains residual charge from the motherboard, which can clear hardware-level glitches that software fixes cannot touch.

1. Shut down your PC completely (do not restart or sleep, fully shut down).
2. If you are on a laptop, unplug the charger and remove the battery if it is removable.
3. Press and hold the power button for 30 seconds.
4. Plug everything back in and power on normally.

This clears any residual charge and forces all hardware to reinitialize from scratch on the next boot.

Frequently Asked Questions

Why did my WiFi stop working after a Windows update?

Windows updates sometimes replace existing WiFi drivers with incompatible versions, disable the WLAN AutoConfig service, or corrupt network settings. These are all fixable without reinstalling Windows.

How do I fix WiFi not showing after a Windows 11 update?

Open Device Manager (Windows + X), expand Network Adapters, and check if your WiFi adapter is listed. If it is disabled, right-click and enable it. If it is missing entirely, click Action, then Scan for hardware changes. If the adapter still does not appear, follow Fix 10 to download and install the driver manually from your laptop manufacturer’s website.

What does the netsh winsock reset command do?

It resets the Winsock catalog to its default clean state, removing any corrupted entries that were blocking network connections. It is safe to run and does not affect your personal files, settings, or installed programs.

Will uninstalling a Windows update break my computer?

Generally no. Uninstalling a recent update reverts your system to its previous state. You lose the bug fixes in that update, but everything else works normally. Microsoft typically releases a corrected version of the update within a few weeks.

Is it safe to reset network settings on Windows 11?

Yes, network reset is completely safe. The only thing to be aware of is that it erases all saved WiFi passwords, so have your WiFi password ready before you run it.

My WiFi adapter is not showing in Device Manager at all. What should I do?

Go to the Action menu in Device Manager and click Scan for hardware changes. If it still does not appear, go to View and select Show hidden devices. If you see the adapter listed as unknown or hidden, try Fix 3 (reinstall driver) and Fix 10 (manual driver install). A power flush (Fix 11) also sometimes resolves this when the adapter is not being detected at all.

If you tried all these fixes and WiFi is still not working, check the Microsoft Community forums for your specific update KB number to see if others have reported the same issue. Microsoft usually addresses widespread update bugs through a follow-up patch within a few weeks.
