How to Fix Wi-Fi Not Working After a Windows 11 Update

If your Wi-Fi stopped working after a Windows 11 update, you may suddenly find that your computer cannot connect to your wireless network, keeps disconnecting, or connects without internet access. In some cases, the Wi-Fi option disappears completely from Settings.

This can happen when an update changes a device driver, exposes an existing compatibility problem, or affects network configuration. However, the timing alone does not prove that Windows Update caused the issue. A router problem or temporary wireless adapter failure can produce similar symptoms.

The best approach is to identify what changed and try the least disruptive fixes first. You usually do not need to reinstall Windows or reset your entire computer just because Wi-Fi stopped working.

This guide explains how to restore Wi-Fi after a Windows 11 update, including how to check your adapter, roll back a driver, uninstall a problematic update when appropriate, and repair network settings.

Why Does Wi-Fi Stop Working After an Update?

Windows updates can install security fixes, change system components, and sometimes deliver hardware drivers. These changes may affect how Windows communicates with a wireless network adapter.

Common possibilities include:

• A new Wi-Fi driver is incompatible with your hardware.
• The previous driver was replaced by a different version.
• The wireless adapter is disabled or not being detected properly.
• Windows network settings have become inconsistent.
• The WLAN AutoConfig service is not running correctly.
• A separate router or internet service problem happened around the same time.

The symptom provides useful clues. If the Wi-Fi option has disappeared, start by checking the adapter and its driver. If Wi-Fi connects but websites do not load, investigate IP configuration and internet connectivity instead.

Before making changes, confirm that your router is working and that another device can access the internet through the same network.

1. Restart Your Computer and Router

Start with a normal restart. Some updates require a restart before all driver and system changes are applied.

Restart Windows 11

1. Save your open work.
2. Open the Start menu.
3. Select the Power icon.
4. Click Restart.
5. Sign in and test your Wi-Fi connection.

Choose Restart rather than relying on closing and reopening the laptop lid.

Restart your router

If the computer still cannot connect, restart your router:

1. Disconnect the router’s power.
2. Wait approximately 30 seconds.
3. Reconnect the power.
4. Allow the router to finish starting.
5. Try connecting your computer again.

If other devices also have no internet access, the router or internet service may be responsible.

If other devices work normally, continue troubleshooting Windows.

2. Check Whether the Wi-Fi Adapter Is Enabled

A disabled wireless adapter can make it appear that Wi-Fi has stopped working entirely.

Check Windows Settings

1. Press Windows + I.
2. Select Network & internet.
3. Open Advanced network settings.
4. Look for the Wi-Fi adapter.
5. If it is disabled, select Enable.

Then open Quick Settings with Windows + A and make sure Wi-Fi and Airplane mode are set appropriately.

Check Device Manager

If the Wi-Fi adapter is missing from Settings:

1. Right-click Start.
2. Open Device Manager.
3. Expand Network adapters.
4. Find your wireless adapter.

Look for a downward arrow, warning icon, or other indication that the device is disabled or experiencing a problem.

If the adapter is disabled, right-click it and select Enable device.

If it has a warning icon, open its Properties and check the Device status message. An error code can provide a clue about whether Windows is having a driver or hardware detection problem.

If the adapter is not listed, select View → Show hidden devices in Device Manager. A hidden or unavailable entry may indicate that Windows is not currently detecting the hardware correctly.

Do not uninstall unrelated adapters. Focus on the wireless device.

3. Run the Windows Network Troubleshooter

Windows 11 provides troubleshooting tools that can detect some common networking problems and suggest repairs.

To run the troubleshooter:

1. Open Settings.
2. Select System.
3. Click Troubleshoot.
4. Open Other troubleshooters.
5. Find the available network or internet troubleshooter.
6. Select Run and follow the instructions.

Depending on your Windows version, troubleshooting may open through the Get Help application.

Apply suggested fixes when appropriate, then test your connection again.

The troubleshooter may not detect driver compatibility issues or problems caused by a specific update. If it reports that it could not identify the problem, continue with the following steps.

4. Roll Back the Wi-Fi Driver

If Wi-Fi stopped working immediately after an update, the wireless driver is one of the first things to investigate.

Rolling back the driver can restore a previously installed version if the newer one is incompatible with your device.

How to roll back the driver

1. Right-click Start.
2. Select Device Manager.
3. Expand Network adapters.
4. Right-click your Wi-Fi adapter.
5. Select Properties.
6. Open the Driver tab.
7. Select Roll Back Driver, if available.
8. Follow the prompts and restart your computer.

You may be asked why you are rolling back the driver. Select the option that best describes your problem.

The button may be unavailable if Windows has no previous driver version to restore.

After restarting, test the Wi-Fi connection.

When this fix makes sense: The issue began after a driver update, and the adapter is still detected by Windows.

If the problem began after a major Windows update rather than a driver update, check the update history and manufacturer support information before assuming a driver rollback will solve it.

5. Install the Correct Wi-Fi Driver

If rolling back is unavailable or unsuccessful, install a compatible driver from your computer manufacturer’s official support website.

Windows may not always select the best driver for a particular laptop or wireless adapter.

Find your computer model

If you are using a laptop, look for its exact model number on the device or in the system information.

You can also press Windows + R, type msinfo32, and press Enter. Check the System Model field.

Download the driver

1. Open the official support website for your laptop or motherboard manufacturer.
2. Search for your exact model.
3. Select the appropriate Windows version.
4. Find the Wireless, WLAN, or Wi-Fi driver.
5. Download the compatible package.
6. Follow the manufacturer’s installation instructions.
7. Restart the computer if requested.

If your computer cannot access the internet, download the driver using another device and transfer it with a USB drive.

Avoid third-party driver-download websites and do not install a driver intended for a different adapter.

If the manufacturer’s driver package includes a specific installation or cleanup procedure, follow those instructions rather than improvising.

6. Reinstall the Wireless Adapter

A driver installation may not completely resolve the problem if the existing adapter configuration is damaged. In that case, reinstalling the wireless adapter through Device Manager may help.

Before starting, download the correct driver if possible. This is especially important if the computer has no other way to access the internet.

Reinstall the adapter

1. Open Device Manager.
2. Expand Network adapters.
3. Right-click the Wi-Fi adapter.
4. Select Uninstall device.
5. Review any option to remove the driver package carefully. Do not select it unless you have a compatible replacement driver available.
6. Confirm the uninstall.
7. Restart the computer.

Windows may detect the adapter and reinstall its driver automatically.

If the adapter does not return, install the driver you downloaded from the manufacturer’s website.

Test the connection after installation.

If the adapter remains absent from Device Manager, check the manufacturer’s hardware troubleshooting instructions and consider whether the device has a hardware issue.

7. Check Windows Update History

Before uninstalling a Windows update, identify which updates were installed around the time the issue began.

Windows maintains an update history that can help you distinguish a recent quality update from a driver update or another system change.

Open update history

1. Press Windows + I.
2. Select Windows Update.
3. Open Update history.
4. Review the recent entries.
5. Look for driver updates or quality updates installed shortly before Wi-Fi stopped working.

Record the update name and installation date.

A recent update is not automatically the cause. The problem could have appeared at the same time as a router failure or an unrelated driver issue.

If you identify a relevant driver update, rolling back that driver is often more targeted than removing an entire Windows update.

If the problem appears to be tied to a Windows quality update and other fixes have failed, consider the next step.

8. Uninstall a Problematic Windows Update

Removing a Windows update can help if a specific update is strongly associated with the problem and less disruptive fixes have failed.

However, this should not be your first step. Updates contain important security and reliability fixes, so removing one may expose your computer to known vulnerabilities or remove other improvements.

How to uninstall an update

1. Open Settings.
2. Select Windows Update.
3. Click Update history.
4. Find Related settings.
5. Select Uninstall updates, if available.
6. Review the installed updates.
7. Select the relevant update and choose Uninstall, if Windows allows it.
8. Follow the instructions and restart your computer.

Not every update can be removed through this screen. Some updates have different removal procedures or are not uninstallable.

If Windows does not offer an uninstall option, do not try to force-remove system components using unfamiliar commands.

After the restart, test Wi-Fi.

If uninstalling the update resolves the problem, check for a corrected update or a compatible driver before leaving the system in that state permanently.

9. Reset Your Network Configuration

If the adapter is detected and the driver appears healthy, incorrect Windows networking settings may be contributing to the problem.

A network reset can remove and reinstall network adapters and restore several network settings to their defaults.

Perform a network reset

1. Open Settings.
2. Select Network & internet.
3. Click Advanced network settings.
4. Select Network reset.
5. Click Reset now.
6. Confirm the action.
7. Restart the computer if prompted.
8. Reconnect to Wi-Fi.

Make sure you know your Wi-Fi password before starting.

A network reset can affect VPN software, virtual adapters, manually assigned IP addresses, and other custom network configurations. You may need to set these up again.

If you use a work-managed computer, consult your IT administrator before performing this step.

A network reset is most useful when Windows detects the adapter but the network configuration remains broken. It cannot fix a physical wireless adapter failure or an internet outage.

10. Renew Your IP Address and Clear DNS

If Wi-Fi connects but Windows reports no internet access, check whether the computer has received a usable IP configuration.

Renew the IP address

Open Command Prompt as administrator and run:

ipconfig /release

Then run:

ipconfig /renew

Windows will attempt to obtain fresh network settings.

If the renewal fails with a DHCP-related error, investigate the router, the adapter connection, or the DHCP configuration.

Clear the DNS cache

Next, run:

ipconfig /flushdns

This clears cached DNS records.

DNS flushing is useful when cached name-resolution information is causing problems, but it will not repair a missing Wi-Fi adapter or a driver that fails to load.

To inspect your connection, run:

ipconfig

Look for the Wi-Fi adapter’s IPv4 Address and Default Gateway.

If the address starts with 169.254, Windows may have assigned itself an automatic private IPv4 address because it did not receive a usable address from DHCP.

These details can help you determine whether the problem is related to IP configuration rather than the Wi-Fi driver itself.

11. Check WLAN AutoConfig

The WLAN AutoConfig service manages wireless network connections in Windows. If it is stopped or not functioning correctly, Windows may have trouble finding networks or connecting to a saved network.

Check the service status

1. Press Windows + R.
2. Type services.msc.
3. Press Enter.
4. Find WLAN AutoConfig.
5. Double-click the service.
6. Check its status and startup type.

On a typical Windows 11 computer, the service should be configured to start automatically.

If it is stopped, select Start if available. If it is already running, you can try Restart.

Close the Services window, open Quick Settings, and check whether Wi-Fi is available.

If the service fails repeatedly or produces an error, investigate the wireless driver and Windows system logs rather than repeatedly restarting the service.

12. Install Available Fixes From Windows Update

If Wi-Fi remains broken, check whether Microsoft has released a fix or a compatible driver update.

Check for updates

1. Open Settings.
2. Select Windows Update.
3. Click Check for updates.
4. Install relevant available updates.
5. Restart the computer if required.

You can also review Advanced options → Optional updates for available driver updates.

Read the descriptions before installing optional drivers. If you have already identified a problematic driver, the manufacturer’s recommended version may be a better choice.

If Windows Update itself is unavailable because your computer has no internet, use another device to check the manufacturer’s support page or obtain the required driver.

Avoid installing unofficial patches that claim to repair Windows networking automatically.

What If the Wi-Fi Option Has Disappeared?

If Windows 11 no longer shows a Wi-Fi option, use a slightly different troubleshooting approach.

Check Device Manager

Open Device Manager and expand Network adapters.

If your wireless adapter appears, check whether it is disabled or has a warning icon.

If it is disabled, enable it. If it has a warning, open Properties and review the Device status message.

Show hidden devices

In Device Manager, select View → Show hidden devices.

If the adapter appears faded, Windows may have previously detected it but is not currently detecting it normally.

Check the manufacturer’s driver

Install a compatible wireless driver from the official support website for your computer.

If the adapter is still missing, check whether your laptop has a hardware wireless switch, a function-key combination, or a manufacturer-specific wireless control.

If the adapter does not appear even after driver troubleshooting, the problem may involve hardware detection or the wireless device itself.

For a USB Wi-Fi adapter, try a different USB port and check whether the device is recognized on another computer.

Frequently Asked Questions

Why did Windows 11 stop connecting to Wi-Fi after an update?

A driver change, compatibility issue, disabled adapter, or altered network configuration may be responsible. The update may be related, but timing alone does not prove causation. Check the adapter and update history before removing updates.

Should I uninstall the latest Windows update?

Only if the issue is strongly linked to a specific update and more targeted fixes have failed. Uninstalling updates can remove security improvements and may not solve a driver or router problem.

Why has my Wi-Fi option disappeared after updating Windows 11?

Windows may not be detecting the wireless adapter correctly, or the driver may be unavailable or incompatible. Check Device Manager, enable the adapter if necessary, and install a compatible driver from the manufacturer’s official website.

Can a Windows update damage my Wi-Fi adapter?

A software update can cause driver compatibility or configuration problems, but that does not mean the physical adapter has been damaged. Check driver status and test appropriate software fixes before concluding that the hardware has failed.

Will network reset fix Wi-Fi after an update?

It may help if the update coincided with a network configuration problem. It will not necessarily fix an incompatible driver, missing hardware, or a router outage. Because a reset changes network settings, use it after simpler troubleshooting.

How can I get a Wi-Fi driver without internet access?

Use another device to visit your computer manufacturer’s official support website. Download the correct wireless driver for your model and Windows version, transfer it using a USB drive, and install it on the affected computer.

Conclusion

If Wi-Fi stops working after a Windows 11 update, start by checking whether the wireless adapter is enabled and whether other devices can connect to the same network.

If the adapter is detected but the connection is broken, try rolling back the driver, installing a compatible version, and checking Windows networking settings. If the Wi-Fi option has disappeared, focus on adapter detection and driver installation first.

Uninstalling a Windows update should be a later option, not the first response. Before doing so, review the update history and try less disruptive solutions.

By identifying whether the issue involves the driver, adapter, IP configuration, or router, you can restore Wi-Fi without unnecessarily resetting or reinstalling Windows.
