If your Windows 11 computer loses internet access every time it wakes up from sleep, you are probably dealing with a problem that affects the wireless adapter, its driver, or the way Windows restores the network connection.

You might notice that the Wi-Fi icon looks normal after opening your laptop, but websites refuse to load. Sometimes the computer disconnects from Wi-Fi completely. In other cases, it stays connected to the router but displays “No Internet.” Restarting the computer may temporarily fix the issue, only for it to return after the next sleep session.

This behavior can be frustrating, especially if you close your laptop frequently throughout the day. Fortunately, you can try several targeted fixes without reinstalling Windows.

This guide explains how to troubleshoot Wi-Fi that stops working after sleep on Windows 11, beginning with quick recovery steps and moving to adapter power settings, drivers, and network configuration.

Why Does Wi-Fi Stop Working After Sleep?

When Windows enters sleep mode, it reduces power consumption by placing hardware into a low-power state. When the computer wakes up, Windows must restore the wireless adapter, reconnect to the saved Wi-Fi network, and resume normal network communication.

Sometimes one part of that process fails.

Common reasons include:

  • The wireless adapter does not resume correctly from its low-power state.
  • The Wi-Fi driver has a compatibility problem.
  • Windows power-management settings interfere with the adapter.
  • The router takes too long to restore the connection.
  • The computer reconnects to Wi-Fi but fails to obtain a usable IP address.
  • The WLAN AutoConfig service is not operating correctly.
  • A recent Windows or driver update introduced a problem.

The most important clue is timing. If Wi-Fi works normally before sleep and consistently fails immediately after waking, investigate power management and the wireless driver before changing unrelated settings.

1. Turn Wi-Fi Off and On Again

Start with the quickest fix. Sometimes Windows wakes up successfully, but the wireless connection does not reconnect properly.

Turning Wi-Fi off and back on forces Windows to establish the wireless connection again.

Follow these steps

  1. Press Windows + A to open Quick Settings.
  2. Select Wi-Fi to turn it off.
  3. Wait approximately 10 seconds.
  4. Turn Wi-Fi back on.
  5. Reconnect to your saved network if necessary.
  6. Open a website to test internet access.

If the internet works again, you may be dealing with a temporary reconnection problem.

However, if this happens after every sleep session, continue to the next steps. Repeatedly toggling Wi-Fi is a workaround, not necessarily a permanent solution.

2. Restart the Wi-Fi Adapter

If turning Wi-Fi off and on does not help, restart the wireless adapter itself.

This can help when the adapter remains in an unresponsive state after the computer wakes up.

Use Windows Settings

  1. Open Settings with Windows + I.
  2. Select Network & internet.
  3. Click Advanced network settings.
  4. Locate your Wi-Fi adapter.
  5. Click Disable.
  6. Wait about 10 seconds.
  7. Click Enable.

Wait for the adapter to reconnect, then test the internet.

Use Device Manager if necessary

If the adapter does not respond through Settings:

  1. Right-click the Start button.
  2. Open Device Manager.
  3. Expand Network adapters.
  4. Find your wireless adapter.
  5. Right-click it and select Disable device.
  6. Wait several seconds.
  7. Right-click it again and select Enable device.

Do not disable unrelated network adapters, especially if you use a VPN or virtual networking software.

If this restores internet access but the issue returns after every sleep session, investigate power management next.

3. Disable Wi-Fi Adapter Power Saving

Windows may use power-management features to reduce energy consumption. Depending on the wireless adapter and driver, these settings can sometimes contribute to connection problems when the computer wakes up.

Changing the adapter’s power-management settings is one of the most relevant fixes to try when the problem occurs specifically after sleep.

Step 1: Open Device Manager

  1. Right-click Start.
  2. Select Device Manager.
  3. Expand Network adapters.
  4. Find your Wi-Fi adapter.
  5. Right-click it and select Properties.

Step 2: Check the Power Management tab

If the adapter has a Power Management tab:

  1. Open the tab.
  2. Look for the option Allow the computer to turn off this device to save power.
  3. If the option is selected, try clearing it.
  4. Click OK.

Restart the computer if needed, then test sleep and wake behavior again.

Important: Not every wireless adapter exposes this option. If you cannot find the Power Management tab, do not assume anything is wrong. Continue with the other solutions.

Disabling this setting may increase power consumption slightly, especially on a laptop. If it does not improve the problem, you can restore the original setting.

4. Check Windows Power Settings

Windows power modes can affect how your computer balances battery life and performance. On some devices, wireless connectivity problems may be influenced by the selected power mode or manufacturer-specific power-management software.

Change the power mode

  1. Open Settings.
  2. Select System.
  3. Click Power & battery.
  4. Find Power mode.
  5. Temporarily select a performance-oriented option available on your device.
  6. Put the computer to sleep and wake it again to test the connection.

The available choices vary by device and configuration.

If the issue disappears in a performance-oriented mode, power management may be contributing to the problem. You can then investigate your manufacturer’s power utility and wireless driver settings.

Do not change every power setting at once. Testing one adjustment at a time makes it easier to determine which change actually helps.

5. Update the Wireless Driver

A wireless driver allows Windows to communicate with the Wi-Fi hardware. If the driver does not handle sleep and wake transitions correctly, the adapter may fail to reconnect even though the rest of the computer resumes normally.

Updating the driver can resolve compatibility problems, particularly if the issue started after a Windows update.

Update through Device Manager

  1. Right-click Start.
  2. Open Device Manager.
  3. Expand Network adapters.
  4. Right-click your wireless adapter.
  5. Select Update driver.
  6. Choose Search automatically for drivers.

Windows will check for a suitable driver, but it may not find the newest version.

Download the manufacturer’s driver

If the problem persists, visit the official support website for your laptop or motherboard manufacturer.

Search using your exact model number and download the appropriate wireless driver for Windows 11.

Install it according to the manufacturer’s instructions, then restart your computer.

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

Avoid generic driver-download websites. A driver intended for a different wireless adapter can introduce additional problems.

6. Roll Back a Recent Driver Update

Sometimes the latest driver is not the best driver for a particular device. If Wi-Fi began failing after a driver update, returning to the previous version may be more effective than installing another update.

How to roll back the driver

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

The rollback option may be unavailable if Windows does not have a previous driver version stored.

After rolling back, test several sleep and wake cycles.

If the problem disappears, the previous driver may be more compatible with your hardware. You should still check the manufacturer’s support information for a stable, recommended driver version.

7. Restart the WLAN AutoConfig Service

Windows uses the WLAN AutoConfig service to manage wireless network connections, including connecting to saved Wi-Fi networks.

If the service is stopped or experiencing problems, the computer may struggle to reconnect after waking from sleep.

Check the service

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

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

If it is stopped, select Start if available. If it is already running, you can select Restart to test whether refreshing the service helps.

Avoid changing unrelated services.

After restarting WLAN AutoConfig, turn Wi-Fi off and on again if needed. Reconnect to your network and check whether the connection works after the next sleep session.

If the service repeatedly stops unexpectedly, investigate system errors and the wireless driver rather than relying on repeated manual restarts.

8. Renew Your IP Address

Sometimes the Wi-Fi adapter reconnects to the router after sleep, but Windows does not have a usable IP configuration.

Renewing the IP address asks the router’s DHCP service for fresh network settings.

Step 1: Open Command Prompt as administrator

  1. Search for Command Prompt in the Start menu.
  2. Select Run as administrator.

Step 2: Release the current IP address

Run:

ipconfig /release

The connection may temporarily disconnect.

Step 3: Request a new IP address

Run:

ipconfig /renew

Wait for the command to finish.

Step 4: Check the result

Run:

ipconfig

Find the Wi-Fi adapter and check its IPv4 Address and Default Gateway fields.

If Windows reports that it cannot contact a DHCP server, the issue may involve the router, adapter connection, or network configuration.

This fix is most useful when the computer reconnects to Wi-Fi but fails to communicate properly afterward. It will not repair a driver that cannot wake up or a router that has lost its internet connection.

9. Reset Winsock and TCP/IP

If the connection repeatedly fails after sleep and other methods have not worked, Windows networking components may need to be reset.

Open Command Prompt as administrator and run:

netsh winsock reset

Then run:

netsh int ip reset

Restart your computer after the commands complete.

Reconnect to Wi-Fi and test the connection before and after sleep.

These commands reset parts of the local Windows networking configuration. They are not a guaranteed fix for sleep-related problems, so use them after the more targeted adapter and driver checks.

If you use a work-managed computer, static IP settings, or specialized VPN software, confirm that resetting networking components will not interfere with your configuration.

10. Disable Fast Startup for Testing

Fast Startup is a Windows feature designed to make certain shutdowns and startups quicker. It uses a form of hibernation for part of the system session.

Fast Startup is not the same as sleep mode, so it is not the first setting to change when Wi-Fi fails specifically after waking from sleep. However, if you also experience problems after shutting down and powering the computer back on, testing Fast Startup may be useful.

How to turn off Fast Startup

  1. Press Windows + R.
  2. Type control.
  3. Press Enter to open Control Panel.
  4. Select Hardware and Sound.
  5. Open Power Options.
  6. Click Choose what the power buttons do.
  7. Select Change settings that are currently unavailable, if shown.
  8. Clear Turn on fast startup (recommended), if the option is available.
  9. Save your changes.

Restart the computer and test a normal shutdown and startup.

If the option is unavailable or the problem occurs only after sleep, skip this step. Focus instead on the wireless adapter, driver, and power-management settings.

11. Install Available Windows Updates

Windows updates sometimes include fixes for networking, device compatibility, and power-management problems.

If your Wi-Fi issue began after an update, check whether Microsoft or your computer manufacturer has released a relevant fix.

Check for updates

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

You can also check Advanced options and Optional updates for compatible driver updates, but do not install every optional driver without considering its relevance.

If the problem began immediately after a particular update, review the update history and your device manufacturer’s support information. Installing more updates may help, but a recent update is not automatically the cause.

12. Reset Network Settings

If the wireless connection still fails after waking from sleep, a Windows network reset may help clear persistent configuration problems.

This is a more disruptive option than restarting the adapter, so try it after the previous solutions.

Perform a network reset

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

A network reset removes and reinstalls network adapters and restores several networking settings to their defaults.

You may need to reconnect to saved networks or reconfigure VPN clients, virtual adapters, static IP settings, and specialized networking software.

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

If the problem remains after the reset, avoid repeating it. Investigate the driver, device power management, and any recurring system errors instead.

How to Prevent the Problem From Returning

Once Wi-Fi works again, test the computer several times rather than assuming the issue is permanently resolved.

Use the following checklist:

  • Put the computer to sleep and wake it up several times.
  • Confirm that Wi-Fi reconnects without manual intervention.
  • Test a website after each wake-up.
  • Keep the wireless driver compatible with your Windows version.
  • Avoid installing drivers from unknown websites.
  • Record whether the problem began after a particular update.
  • If only one router causes the issue, investigate that router’s settings and firmware.

If your laptop has a manufacturer-provided power-management application, check whether it offers wireless or battery-saving options that affect the network adapter.

If Wi-Fi fails only after sleep while Ethernet continues working, that points toward the wireless adapter, its driver, or wireless reconnection rather than a complete loss of internet service.

If multiple devices lose internet access at the same time, investigate the router and internet provider instead.

Frequently Asked Questions

Why does Wi-Fi stop working when I wake up Windows 11?

The wireless adapter may fail to resume correctly, the driver may have a compatibility issue, or Windows may struggle to restore the connection. Adapter power management and driver updates are good places to start.

Why does restarting my laptop fix Wi-Fi temporarily?

Restarting can reinitialize the wireless adapter and networking components. If the problem returns after sleep, the underlying cause may still be present in the driver, power settings, or network configuration.

Should I disable power saving for my Wi-Fi adapter?

It is a reasonable troubleshooting test when the problem occurs after sleep. If changing the setting does not help, restore it to its previous state. Disabling power saving may increase battery consumption.

Does updating the Wi-Fi driver fix sleep problems?

It can, particularly when the existing driver is outdated or incompatible with Windows 11. If the issue started after an update, rolling back to a previously working driver may also help.

Why does Wi-Fi connect after sleep but websites still do not work?

Windows may have reconnected to the wireless router without obtaining a usable IP configuration, or DNS and other network components may not be working correctly. Renewing the IP address and testing DNS can help narrow down the cause.

Is network reset safe?

Network reset is a built-in Windows troubleshooting option, but it changes networking configuration. It may require you to reconnect to Wi-Fi or reconfigure VPNs, virtual adapters, and custom network settings. It is best used after simpler fixes fail.

Conclusion

When Wi-Fi stops working after sleep on Windows 11, concentrate on the steps that directly affect wireless reconnection.

Start by toggling Wi-Fi and restarting the adapter. Then check its power-management settings, update or roll back the driver, and inspect WLAN AutoConfig. If the adapter reconnects but internet access remains unavailable, renew the IP address and investigate the network configuration.

A network reset can be useful when other fixes fail, but it should not be the first response to a recurring sleep problem.

Test the connection after several sleep cycles. If the issue continues, note whether Wi-Fi disappears entirely, remains connected without internet, or affects other devices as well. Those details will help identify whether the problem lies with Windows, the wireless adapter, or the router.
