When a Windows 11 laptop or desktop suddenly loses WiFi, the problem can feel urgent, especially when work, streaming, updates, or online meetings depend on a stable connection. In many cases, the cause is not a broken router or a damaged computer; it is usually a setting, driver issue, network conflict, power-saving feature, or temporary Windows glitch. A careful step-by-step approach helps identify the cause quickly and avoids unnecessary resets or hardware replacements.
TLDR: If Windows 11 WiFi is not working, the fastest fixes usually include restarting the PC and router, checking Airplane mode, reconnecting to the network, and running the Windows network troubleshooter. If that does not help, the user should update or reinstall the WiFi driver, reset network settings, and check whether power-saving options are disabling the wireless adapter. Hardware issues are less common, but they should be considered if the WiFi adapter disappears completely or no networks are detected.

Common Signs of Windows 11 WiFi Problems
WiFi issues in Windows 11 can appear in several ways. A user may see the WiFi icon missing from the taskbar, a connected network with “No Internet”, slow or unstable browsing, repeated disconnections, or no available networks at all. Sometimes the computer connects to WiFi but specific apps cannot access the internet. In other cases, the WiFi adapter may not appear in Device Manager, which points to a driver, hardware, or BIOS-level problem.
Before changing advanced settings, it is useful to identify the exact symptom. If other devices, such as phones or tablets, also cannot connect, the router or internet service may be the source. If only the Windows 11 device is affected, the issue is more likely related to Windows settings, drivers, or the wireless adapter.
1. Restart the Computer and Router
The simplest fix is often the most effective. Restarting the Windows 11 computer clears temporary system glitches, refreshes network services, and reloads the wireless adapter. Restarting the router also helps because routers can become overloaded, especially after long periods of uptime.
The recommended process is simple:
- Shut down or restart the Windows 11 computer.
- Unplug the router and modem from power.
- Wait at least 30 to 60 seconds.
- Plug the modem and router back in.
- Wait until all connection lights stabilize.
- Turn the computer back on and reconnect to WiFi.
If the network returns after this process, the issue was likely temporary. If the problem comes back frequently, the router firmware, WiFi driver, or adapter power settings may need attention.
2. Check Airplane Mode and WiFi Settings
Windows 11 includes quick controls that can easily disable wireless connections by accident. A user should open the Quick Settings panel by selecting the network, sound, or battery area on the taskbar. From there, it is important to confirm that Airplane mode is turned off and WiFi is turned on.
Some laptops also include a physical wireless switch or keyboard shortcut, usually involving the Fn key and a function key with a wireless symbol. If this key combination disables the adapter, Windows may show no available WiFi networks even though the router is working normally.
If WiFi is missing from Quick Settings completely, the wireless adapter may be disabled, its driver may have failed, or Windows may not be detecting the device correctly.
3. Forget and Reconnect to the WiFi Network
Saved network profiles can become outdated after router changes, password updates, security setting changes, or Windows updates. Forgetting the network forces Windows 11 to create a fresh connection profile.
To forget a WiFi network, the user can follow this path:
- Open Settings.
- Go to Network & internet.
- Select WiFi.
- Choose Manage known networks.
- Select the affected network and click Forget.
- Reconnect by choosing the network again and entering the password.
This method is especially useful when Windows shows “Can’t connect to this network” or repeatedly asks for a password even when the password is correct.
4. Run the Windows 11 Network Troubleshooter
Windows 11 includes built-in troubleshooters that can automatically detect and repair common network problems. While the troubleshooter does not fix every issue, it can restart services, reset adapter settings, and identify configuration problems.
To run it, the user should open Settings, go to System, select Troubleshoot, then choose Other troubleshooters. From there, the Network and Internet troubleshooter can be launched.
If Windows reports that the default gateway is unavailable, DNS is not responding, or the adapter has an invalid IP configuration, the problem may involve router communication or local TCP/IP settings. The next steps can help repair those deeper network issues.
5. Disable and Re enable the WiFi Adapter
Disabling and re enabling the WiFi adapter resets the adapter without requiring a full system reboot. This can fix temporary driver locks, failed background services, or adapter communication errors.
The process is as follows:
- Open Settings.
- Select Network & internet.
- Choose Advanced network settings.
- Find the WiFi adapter under Network adapters.
- Select Disable, wait a few seconds, then select Enable.
After the adapter is enabled again, the user should check whether available networks appear and whether the computer can reconnect successfully.
6. Update the WiFi Driver
A faulty, outdated, or incompatible wireless driver is one of the most common reasons for WiFi failure in Windows 11. This is especially true after a major Windows update or when using older laptops upgraded from Windows 10.
To update the driver, the user can right-click the Start button and open Device Manager. Under Network adapters, the wireless adapter should be listed, often with names such as Intel, Realtek, Qualcomm, Broadcom, or MediaTek. The user can right-click the adapter, choose Update driver, then select Search automatically for drivers.
However, Windows does not always find the newest driver. For best results, the user should also check the computer manufacturer’s official support page. Laptop brands often provide customized WiFi drivers designed for the exact model. Installing the manufacturer’s driver can solve problems that the generic Windows driver cannot.
7. Reinstall the Wireless Adapter Driver
If updating the driver does not work, reinstalling it may help. This removes the current driver configuration and forces Windows to rebuild it.
In Device Manager, the user should right-click the wireless adapter and select Uninstall device. If an option appears to delete the driver software, it should only be selected if a replacement driver is already available from the manufacturer. After uninstalling, the computer should be restarted. Windows will usually reinstall the adapter automatically.
If the WiFi adapter does not return after restarting, the user may need to install the driver manually using another internet connection, such as Ethernet, USB tethering from a phone, or a driver downloaded on another device.
8. Check Power Management Settings
Windows 11 may turn off the wireless adapter to save power, especially on laptops. This can cause random disconnections, WiFi disappearing after sleep mode, or failure to reconnect after waking the device.
To check this setting, the user should open Device Manager, expand Network adapters, right-click the WiFi adapter, and select Properties. Under the Power Management tab, the option “Allow the computer to turn off this device to save power” should be unchecked if connection stability is a problem.
It may also help to adjust the power plan. Under Settings > System > Power & battery, choosing a balanced or best performance mode can reduce aggressive power saving that interferes with wireless networking.
9. Reset Network Settings
A network reset is a stronger fix that removes and reinstalls network adapters, clears saved configurations, and restores default networking components. It can solve stubborn problems caused by corrupted settings, VPN conflicts, old virtual adapters, or broken TCP/IP configurations.
The user can find this option under Settings > Network & internet > Advanced network settings > Network reset. After selecting Reset now, Windows will restart.
Important: This process removes saved WiFi profiles, so the network password will need to be entered again. VPN clients, virtual network adapters, or custom DNS settings may also need to be reconfigured afterward.
10. Use Command Prompt Network Repairs
For persistent connection issues, Windows networking commands can refresh IP settings, clear DNS history, and reset core network components. These commands should be run in Command Prompt as administrator.
ipconfig /releaseipconfig /renewipconfig /flushdnsnetsh winsock resetnetsh int ip reset
After running these commands, the computer should be restarted. These repairs are useful when websites fail to load, DNS errors appear, or the device connects to WiFi but cannot access the internet.
11. Check Router Compatibility and Security Settings
Sometimes the Windows 11 device is working correctly, but the router settings create compatibility problems. Older routers, unusual encryption settings, hidden SSIDs, MAC filtering, or crowded wireless channels can prevent a stable connection.
The router should ideally use WPA2 or WPA3 security. If the router uses outdated WEP security, Windows may refuse or struggle to connect. If the device has problems on a 5 GHz network, testing the 2.4 GHz band may help, since 2.4 GHz has better range. On the other hand, if the 2.4 GHz band is crowded, the 5 GHz band may provide a cleaner connection.
If many nearby networks are visible, changing the router’s WiFi channel can reduce interference. Firmware updates for the router can also improve compatibility with newer Windows 11 devices.
12. Look for Windows Updates
Windows updates can both cause and fix WiFi problems. If an update introduced a bug, Microsoft or the device manufacturer may release a later patch. The user should open Settings > Windows Update and install available updates, including optional driver updates if they relate to networking.
If WiFi stopped working immediately after a recent update, the user may review update history and consider uninstalling the latest quality update. This should be done carefully, as updates often include security fixes. If uninstalling an update restores WiFi, the user should monitor for a corrected update later.
13. Check for VPN, Firewall, or Security Software Conflicts
VPN clients, third-party firewalls, antivirus suites, and privacy tools can interfere with network connections. The computer may appear connected to WiFi but fail to load websites or apps. Temporarily disabling a VPN or security tool can help confirm whether it is causing the issue.
If disabling the software fixes the connection, the user should update that software, reset its network rules, or reinstall it. In some cases, removing old VPN adapters from Advanced network settings helps restore normal WiFi behavior.
14. Determine Whether the WiFi Adapter Has Failed
If no troubleshooting step works, the wireless adapter itself may be failing. Warning signs include the adapter disappearing from Device Manager, repeated hardware error codes, WiFi dropping even on multiple networks, or the computer never detecting available networks while other devices connect normally.
A simple test is to use a USB WiFi adapter. If the USB adapter connects successfully, the built-in wireless card may be damaged or poorly connected. On some laptops, the internal WiFi card can be replaced, while on others, professional service may be required.
Best Troubleshooting Order
For the fastest results, the user should follow a logical order rather than changing settings randomly:
- Restart the computer and router.
- Check WiFi, Airplane mode, and keyboard wireless controls.
- Forget and reconnect to the network.
- Run the Windows network troubleshooter.
- Disable and re enable the WiFi adapter.
- Update or reinstall the WiFi driver.
- Check power management settings.
- Reset network settings.
- Review router, VPN, firewall, and update conflicts.
- Test for hardware failure if the issue continues.
Most Windows 11 WiFi problems are solved before the final steps. Driver updates, network resets, and router restarts are particularly effective. If the issue continues across multiple WiFi networks and after a clean driver installation, hardware testing becomes more important.
FAQ
Why is the WiFi option missing in Windows 11?
The WiFi option may be missing because the wireless adapter is disabled, the driver has failed, Airplane mode is active, or Windows is not detecting the adapter. Checking Device Manager is usually the best first step.
Why does Windows 11 say connected but no internet?
This usually means the computer is connected to the router but cannot reach the internet. Possible causes include router problems, DNS issues, invalid IP settings, VPN conflicts, or an outage from the internet provider.
Does resetting network settings delete anything important?
A network reset removes saved WiFi networks, adapter settings, VPN adapters, and custom network configurations. Personal files are not deleted, but WiFi passwords and special network settings may need to be entered again.
Should the WiFi driver be updated from Windows Update or the manufacturer?
Windows Update is convenient, but the manufacturer’s support page often provides the most compatible driver for a specific laptop or desktop model. If Windows Update does not fix the issue, the manufacturer’s driver should be tried.
When should a user suspect hardware failure?
Hardware failure becomes more likely when the WiFi adapter disappears from Device Manager, no networks are detected anywhere, driver reinstallations fail, or an external USB WiFi adapter works while the built-in adapter does not.
