How to Fix Wi-Fi Keeps Disconnecting on Windows 11

You are working, watching a video, or attending an online meeting when your Wi-Fi suddenly disconnects. A few seconds later, it reconnects, only to drop again. Sometimes the network disappears completely, and other times Windows stays connected but stops loading websites.

Repeated Wi-Fi disconnections can make even basic tasks frustrating. The problem becomes especially annoying when it happens several times a day or only after your laptop wakes from sleep.

The cause is not always your internet provider. Windows power settings, outdated network drivers, router interference, weak signal strength, and incorrect network configuration can all contribute to unstable Wi-Fi.

This guide explains how to fix Wi-Fi that keeps disconnecting on Windows 11. You will start with simple checks and move toward more advanced solutions, with clear instructions for identifying whether the problem is coming from your computer or your router.

1. Identify Why Wi-Fi Keeps Disconnecting

Before changing settings, pay attention to when the connection drops. The timing can provide useful clues about the underlying problem.

For example, if Wi-Fi disconnects whenever you move to another room, weak signal strength or interference may be responsible. If it happens immediately after your laptop wakes from sleep, power management or driver compatibility deserves attention.

Here are some common patterns:

These are clues, not definitive diagnoses. Work through the following methods in order and test your connection after each major change.

2. Check Whether Other Devices Have the Same Problem

This simple test can save you considerable time.

Connect your phone or another laptop to the same Wi-Fi network. Use the devices normally for a few minutes and see whether they disconnect too.

If multiple devices lose their connection at the same time, investigate the router, modem, wireless interference, or your internet provider.

If only your Windows laptop disconnects, focus on the laptop’s wireless adapter, drivers, power settings, and network configuration.

Also distinguish between two different problems:

• Wi-Fi disconnects: Windows loses its connection to the wireless network.
• Wi-Fi stays connected, but the internet stops working: The laptop may still communicate with the router while the router or internet service has a problem.

The second situation requires internet connectivity troubleshooting rather than focusing exclusively on the wireless adapter.

3. Restart Your Router and Computer

A router can develop temporary problems that affect wireless connections. Restarting it is a useful early step, particularly when several devices are affected.

Follow these steps:

1. Save any open work.
2. Turn off your router using its power switch or unplug its power cable.
3. If you have a separate modem or optical network terminal, follow your provider’s instructions for restarting it.
4. Wait about 30 seconds.
5. If the modem and router are separate, power on the modem or ONT first.
6. Wait for its connection indicators to stabilize.
7. Turn on the router and give it time to restart.
8. Restart your Windows computer.
9. Reconnect to Wi-Fi and observe whether the problem returns.

Do not press and hold the router’s factory reset button. A factory reset can erase saved network names, passwords, and other configuration settings.

If restarting the equipment solves the problem only temporarily, investigate router firmware, overheating, signal quality, and whether multiple devices experience the same disconnections.

4. Move Closer to the Router and Check Interference

Wireless signals weaken with distance and can be affected by walls, floors, furniture, and other sources of interference.

If your laptop disconnects mainly in a bedroom, upstairs room, or area far from the router, signal quality may be responsible.

Try this test:

1. Move your laptop into the same room as the router.
2. Connect to your usual Wi-Fi network.
3. Use the computer for several minutes.
4. Check whether the connection remains stable.
5. Return to your normal location and compare the results.

If Wi-Fi works reliably near the router but fails farther away, changing Windows drivers may not solve the underlying problem.

Consider relocating the router to a more central, open position. Avoid placing it inside a closed cabinet or directly behind large metal objects.

Other wireless devices and neighboring networks can also contribute to interference. If your router supports both 2.4 GHz and 5 GHz Wi-Fi, test both bands if available.

The 2.4 GHz band often reaches farther, while 5 GHz can provide better performance at shorter distances. Actual performance depends on the router, walls, interference, and the capabilities of your laptop.

5. Forget and Reconnect to Your Wi-Fi Network

Windows saves connection details for networks you have used before. If the saved configuration becomes problematic, forgetting the network and reconnecting can help.

Before proceeding, make sure you know the correct Wi-Fi password.

1. Open Settings.
2. Select Network & internet.
3. Choose Wi-Fi.
4. Open Manage known networks.
5. Find your Wi-Fi network.
6. Select Forget.
7. Return to the available Wi-Fi networks.
8. Select your network and enter the password.

After reconnecting, use the computer normally and check whether the connection remains stable.

This method is particularly useful if the router’s configuration or Wi-Fi password has changed.

It will not repair a defective wireless adapter or a router that repeatedly loses power, so continue troubleshooting if the problem returns.

6. Disable Wi-Fi Power-Saving Settings

Windows may manage your wireless adapter’s power consumption to improve battery life. Depending on the adapter and driver, power-management behavior can contribute to connectivity problems.

This is worth checking if Wi-Fi disconnects after your laptop wakes from sleep or when the computer is running on battery.

Change the adapter’s power-management setting

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 Properties.
6. Open the Power Management tab, if available.
7. Look for Allow the computer to turn off this device to save power.
8. If the option is present, try clearing the checkbox.
9. Select OK and test Wi-Fi again.

Not every network adapter exposes this setting. If the tab is missing, do not worry; continue to the next method.

Check your Windows power mode

You can also open Settings > System > Power & battery and review the available power-mode options.

Temporarily testing a less restrictive power mode may help determine whether power management is contributing to the problem.

The available settings depend on your laptop and Windows version. Restore your preferred power settings if changing them makes no difference.

7. Update the Wi-Fi Driver

The wireless driver allows Windows to communicate with your laptop’s Wi-Fi hardware. An outdated, corrupted, or incompatible driver can cause repeated disconnections.

Updating it is especially worth trying if the problem began after a Windows update or driver change.

Update through Device Manager

1. Right-click Start.
2. Select Device Manager.
3. Expand Network adapters.
4. Right-click your Wi-Fi adapter.
5. Select Update driver.
6. Choose Search automatically for drivers.
7. Follow any instructions shown on the screen.

Windows may report that the best driver is already installed even when the manufacturer’s website has a newer version.

Download the driver from the manufacturer

Visit your laptop manufacturer’s official support website and search for your exact model.

Download the Wi-Fi driver that matches your hardware and Windows version. If the laptop uses an Intel, Realtek, Qualcomm, or other wireless adapter, ensure the driver is intended for that specific device.

If Wi-Fi is unreliable, download the driver using another device and transfer it through a USB drive.

Avoid downloading drivers from unknown websites or installing several different driver packages in an attempt to find one that works.

Restart your computer if required, reconnect to Wi-Fi, and check whether the connection remains stable.

8. Roll Back a Problematic Driver

Sometimes the latest driver is not the best option for a particular laptop. A new driver can introduce a compatibility problem, especially if the disconnections started immediately after an update.

If Device Manager offers a rollback option, you can consider returning to the previous driver.

1. Open Device Manager.
2. Expand Network adapters.
3. Right-click your wireless adapter.
4. Select Properties.
5. Open the Driver tab.
6. Select Roll Back Driver, if the option is available.
7. Follow the instructions and restart your computer if needed.

The rollback option may be unavailable if Windows has no previous driver package stored.

Do not roll back a driver simply because it is old. Use this method when there is a reasonable connection between a recent driver change and the onset of the problem.

If the previous driver restores stability, check the manufacturer’s support information before installing another update.

9. Reset Your IP Address and Network Configuration

Repeated disconnections can sometimes be accompanied by IP configuration problems. Windows provides several commands that may help reset networking components.

Use these steps only after checking your router, signal, and wireless driver.

Open Command Prompt as administrator

1. Open Start.
2. Search for Command Prompt.
3. Select Run as administrator.
4. Approve the permission prompt.

Run the following commands separately:

ipconfig /release

This releases the current IPv4 address for the relevant adapters and may temporarily interrupt connectivity.

ipconfig /renew

This asks the network’s DHCP server, usually the router, to assign an IP configuration again.

ipconfig /flushdns

This clears the Windows DNS resolver cache.

If the problem persists, you can also reset the Winsock catalog:

netsh winsock reset

And reset TCP/IP configuration:

netsh int ip reset

Restart your computer after running the reset commands.

These commands will not fix weak Wi-Fi signals or a failing router. They are intended for networking configuration problems.

If you use manually configured IP addresses, enterprise networking software, or a work VPN, check with your administrator before resetting components.

10. Change Wi-Fi Band Settings

Many modern routers support more than one wireless band. Your laptop may connect through 2.4 GHz or 5 GHz, depending on the adapter, router configuration, and network name.

The two bands behave differently.

If your laptop disconnects in certain locations, testing another band can help.

If your router provides separate Wi-Fi names for each band, connect to the alternative network and observe whether stability improves.

Some routers combine the bands under a single network name and automatically steer devices between them. In that case, check your router’s documentation before changing its configuration.

You can also inspect the wireless adapter’s advanced settings in Device Manager.

1. Open Device Manager.
2. Expand Network adapters.
3. Right-click your wireless adapter.
4. Select Properties.
5. Open the Advanced tab, if available.
6. Review the available band or roaming options.

The options and names vary by adapter. Avoid changing several advanced settings at once, and record the original values so you can restore them.

11. Check VPN and Security Software

VPN applications and certain security tools can affect network connectivity, although they are not the most common explanation for every Wi-Fi disconnection.

If the problem started after installing a VPN, firewall, or network-filtering application, investigate that software.

First, disconnect the VPN temporarily and test your connection.

If Wi-Fi remains connected but websites stop loading only while the VPN is active, the VPN connection or its network configuration may be involved.

Also review any recent changes to security software. Avoid disabling antivirus protection or your firewall permanently.

If you are using a work laptop, do not remove required security software or change managed VPN settings without permission.

12. Install Windows Updates

Windows updates may include improvements to wireless connectivity, compatibility fixes, and updated system components.

To check for updates:

1. Open Settings.
2. Select Windows Update.
3. Choose Check for updates.
4. Install applicable updates.
5. Restart your computer if prompted.
6. Test your Wi-Fi connection.

You can also review optional driver updates when available, but confirm that any driver matches your hardware.

If the problem began immediately after a Windows update, investigate whether a newer driver is available from the computer manufacturer.

Avoid uninstalling security updates at random. If you suspect a specific update caused the issue, check Microsoft’s documentation and use a targeted troubleshooting approach.

13. Reset Windows Network Settings

If all previous methods fail, Windows 11 offers a network reset option.

This removes and reinstalls network adapters and restores certain networking components to their default settings.

Before using it, understand that you may need to reconnect to Wi-Fi and reconfigure VPN clients, virtual network adapters, or custom IP settings.

To reset the network:

1. Open Settings.
2. Select Network & internet.
3. Open Advanced network settings.
4. Select Network reset.
5. Review the information provided.
6. Select Reset now if you want to proceed.
7. Restart the computer if prompted.
8. Reconnect to Wi-Fi and test the connection.

Network reset is not the same as resetting Windows to factory settings. It targets networking components rather than reinstalling the entire operating system.

Because it can affect other networking software, save your custom settings before proceeding.

14. When to Suspect a Hardware Problem

If Wi-Fi continues to disconnect after driver troubleshooting and network resets, the wireless adapter itself may be faulty.

Look for additional clues:

• The Wi-Fi adapter repeatedly disappears from Device Manager.
• Windows reports hardware errors.
• The laptop disconnects across several known-good networks.
• The problem persists with a suitable manufacturer driver.
• Other devices remain stable on the same networks.

These symptoms do not prove hardware failure, but they justify further investigation.

Check Device Manager for warning icons and error messages. If your laptop includes built-in hardware diagnostics, you can use the manufacturer’s official tools to test the wireless adapter.

A compatible external USB Wi-Fi adapter can also help determine whether the built-in adapter is responsible. If the external adapter works reliably under similar conditions, the internal adapter or its driver may need further attention.

Do not open a laptop or replace internal components unless you understand the procedure and any warranty implications. Contact the manufacturer or a qualified repair technician if necessary.

Frequently Asked Questions

Why does Wi-Fi keep disconnecting on Windows 11?

Common causes include weak signal strength, wireless interference, router problems, outdated drivers, and power-management settings. Test another device on the same network to determine whether the issue is limited to your computer.

How do I stop Wi-Fi from disconnecting after sleep mode?

Check the wireless adapter’s Power Management settings in Device Manager, if available. Updating the manufacturer’s Wi-Fi driver may also help. Test one change at a time so you can identify what resolves the problem.

Can an outdated Wi-Fi driver cause random disconnections?

Yes. A driver that is outdated, corrupted, or incompatible with your Windows version can cause connection instability. Install a compatible driver from your laptop or adapter manufacturer’s official support website.

Why does my laptop disconnect while my phone works normally?

If your phone remains connected to the same Wi-Fi network, investigate the laptop’s wireless driver, power settings, adapter, and saved network configuration. If multiple devices disconnect together, focus on the router and internet service instead.

Should I reset my router to fix Wi-Fi disconnections?

Start with a normal restart rather than a factory reset. A restart does not normally erase saved settings, while a factory reset can remove your network name, password, and custom configuration.

Is 2.4 GHz better than 5 GHz for a stable connection?

It depends on your environment. The 2.4 GHz band often provides better range, while 5 GHz can perform better at shorter distances. Walls, interference, router capabilities, and the laptop’s wireless adapter all affect the result.

Will network reset delete my files?

A Windows network reset is not designed to delete personal files. However, it can remove network configurations and affect VPN or virtual networking software. Back up important work and record custom settings before proceeding.

When should I replace my Wi-Fi adapter?

Consider replacement only after checking drivers, router behavior, signal quality, and Windows configuration. If the adapter repeatedly disappears or fails across different networks, a hardware problem becomes more plausible. Manufacturer diagnostics can help confirm the issue.

Conclusion

When Wi-Fi keeps disconnecting on Windows 11, the most effective fix depends on when the problem occurs and whether other devices experience it too.

Start by testing another device, restarting the router, and checking signal strength. If the problem is limited to your laptop, investigate power-management settings, update or roll back the wireless driver, and review the saved network configuration.

Advanced options such as resetting TCP/IP or performing a network reset can help with persistent software problems, but they should come after the simpler checks.

Avoid changing multiple settings simultaneously. Test the connection after each step and record any changes that improve or worsen stability.

This methodical approach makes it easier to identify the actual cause, avoid unnecessary repairs, and restore a reliable Wi-Fi connection.
