Wi-Fi Keeps Disconnecting After a Windows 11 Update? 8 Ways to Fix It (2026)

Did your Wi-Fi start disconnecting and reconnecting frequently after installing a Windows 11 update? While Windows updates are designed to improve security, stability, and performance, they can sometimes introduce unexpected networking problems. Many users report that their wireless connection becomes unstable immediately after installing a feature update, a cumulative update, or a new network driver.

In most cases, Wi-Fi disconnection issues after a Windows 11 update are caused by driver compatibility problems, modified network settings, power management changes, or bugs introduced during the update process. As a result, your laptop may randomly lose its connection, reconnect automatically, or fail to maintain a stable wireless connection even when the router and internet service are working normally. In this guide, we’ll explain why Wi-Fi keeps disconnecting after a Windows 11 update and walk you through 8 effective solutions to restore a stable wireless connection.

Why Does Wi-Fi Keep Disconnecting After a Windows 11 Update?

If your Wi-Fi connection started dropping only after installing a Windows 11 update, the update may have changed network settings, installed a different driver, or introduced a compatibility issue with your wireless adapter. While these problems are usually temporary, they can make the connection unstable until the underlying issue is corrected.

Common reasons why Wi-Fi keeps disconnecting after a Windows 11 update include:

• Network Driver Compatibility Issues: Windows Update may install a newer Wi-Fi driver that is incompatible with your wireless adapter or laptop model.
• Corrupted Network Settings: During the update process, network configurations can become corrupted, causing intermittent connectivity problems.
• Power Management Changes: Some updates may reset power-saving settings, allowing Windows to turn off the Wi-Fi adapter to conserve power.
• Third-Party Software Conflicts: VPN applications, security software, or network utilities may become incompatible after a Windows update.
• Update-Related Bugs: Occasionally, a Windows update may introduce temporary bugs that affect wireless networking on certain hardware configurations.
• Incorrect Driver Installation: Windows may replace a manufacturer-provided driver with a generic driver that does not work properly with your Wi-Fi adapter.

The good news is that most Wi-Fi issues related to updates can be resolved by adjusting adapter settings, reinstalling drivers, resetting network components, or removing a problematic update. Follow the solutions below until your wireless connection becomes stable again.

Fix 1: Restart Your PC and Router

Temporary glitches during or immediately after a Windows 11 update can affect wireless networking services. Restarting your PC reloads Windows network components, while restarting the router refreshes the connection and clears temporary communication issues.

Restart Your Windows 11 PC

1. Save any open work.
2. Click Start > Power > Restart.
3. Wait for Windows to fully restart.

Restart Your Router

1. Turn off your router and modem (if separate).
2. Unplug the power cables.
3. Wait for at least 30 seconds.
4. Plug the modem back in and allow it to fully start.
5. Turn on the router and wait for the indicator lights to stabilize.

Once both devices have restarted, reconnect to your Wi-Fi network and monitor the connection for a few minutes. If the Wi-Fi continues to disconnect after the update, proceed to the next solution.

Fix 2: Disable and Re-Enable the Wi-Fi Adapter

A Windows 11 update can sometimes leave the wireless adapter unstable, causing intermittent disconnections or preventing it from maintaining a reliable connection. Disabling and re-enabling the adapter forces Windows to reload the device without requiring a complete driver reinstall.

1. Press Windows + X and select Device Manager.
2. Expand Network adapters.
3. Right-click your Wi-Fi adapter and select Disable device.
4. Wait for about 10 seconds.

If the Wi-Fi connection becomes stable after re-enabling the adapter, the issue was likely caused by a temporary driver or device initialization problem introduced during the Windows update. If the problem continues, move on to the next fix.

Fix 3: Roll Back the Wi-Fi Driver

One of the most common causes of Wi-Fi disconnections after a Windows 11 update is a newly installed network driver. In some cases, Windows Update replaces a stable driver with a newer version that is incompatible with your wireless adapter. Rolling back the driver restores the previously working version.

1. Press Windows + X and select Device Manager.
2. Expand Network adapters.
3. Right-click your Wi-Fi adapter and select Properties.
4. Open the Driver tab.

7. Restart your computer after the rollback is complete.

After Windows restarts, reconnect to your Wi-Fi network and monitor the connection. If the disconnections started after a recent update, reverting to the previous driver version often resolves the problem.

Note: If the Roll Back Driver button is grayed out, Windows does not have a previous driver version available. In that case, continue to the next solution.

Fix 4: Update or Reinstall the Wi-Fi Driver

If rolling back the driver is not possible or does not resolve the issue, updating or reinstalling the Wi-Fi driver can help fix compatibility problems introduced by the Windows 11 update. Installing the latest driver from your laptop or adapter manufacturer often provides better stability than the version installed through Windows Update.

Update the Wi-Fi Driver

1. Press Windows + X and select Device Manager.
2. Expand Network adapters.
3. Right-click your Wi-Fi adapter and select Update driver.
4. Choose Search automatically for drivers.

Reinstall the Wi-Fi Driver

If updating does not help:

1. Right-click the Wi-Fi adapter and select Uninstall device.
2. Confirm the uninstall when prompted.
3. Restart your computer.
4. Windows will automatically reinstall the driver during startup.

For the best results, download the latest Wi-Fi driver directly from your laptop manufacturer’s support website and install it manually. Also, you can use a third-party driver update tool to automatically scan and install the latest driver on your device. Once installed, reconnect to your wireless network and check whether the connection remains stable.

Fix 5: Disable Power Saving for the Wi-Fi Adapter

Some Windows 11 updates may reset power management settings or change how the operating system handles wireless adapters. As a result, Windows may turn off the Wi-Fi adapter to save power, causing the connection to disconnect unexpectedly.

1. Press Windows + X and select Device Manager.
2. Expand Network adapters.
3. Right-click your Wi-Fi adapter and select Properties.
4. Open the Power Management tab.
5. Uncheck Allow the computer to turn off this device to save power.
6. Click OK to save the changes.

Once the reset is complete, monitor the connection to see whether the random disconnections have stopped. If the issue began immediately after a Windows update and still persists, the update itself may be responsible, which is covered in the next solution.

Fix 8: Uninstall the Recent Windows Update

If your Wi-Fi connection was stable before the update and the disconnections started immediately afterward, the update itself may be causing the problem. Removing the most recent Windows update can help determine whether a bug, compatibility issue, or driver change introduced by the update is responsible.

Note: Only uninstall a recent update if the Wi-Fi issue clearly started after installing it. Windows may reinstall the update later unless Microsoft releases a fix.

1. Press Windows + I to open Settings.
2. Go to Windows Update.
3. Click Update history.
4. Scroll down and select Uninstall updates.
5. Locate the most recently installed update.
6. Select the update and click Uninstall.
7. Follow the on-screen instructions to complete the removal.
8. Restart your computer.

After your PC restarts, reconnect to your Wi-Fi network and monitor the connection. If the disconnections stop after removing the update, the issue was likely caused by the update itself or changes it made to your network drivers or settings.

If none of the solutions above resolve the problem, test your device on a different Wi-Fi network or connect directly to the router using an Ethernet cable. This can help determine whether the issue is related to Windows 11, your wireless adapter, the router, or your internet service provider.
