If your Windows 11 computer keeps disconnecting from your Wi-Fi network, you may be dealing with bugs in the system causing connectivity-related issues. Alternatively, the problem may be caused due to outdated network drivers or incorrect power management settings. Depending on the cause, there are various solutions that you can try out to deal with the problem. Fortunately, these are quite easy and won't require much time, so you can get your internet connection stabilized in just a few minutes.

Try some basic fixes

Before you try out advanced solutions, you should try a few basic fixes if your Wi-Fi keeps getting disconnected on Windows 11. First, restart your router to get rid of any glitches that may be affecting it and causing problems. Doing so will make your PC reconnect to the network, which may help resolve any minor issues affecting the connection between your computer and the router.

If your router has a power button, press it to turn it off and wait for a few seconds before powering it on. On the other hand, if there is no power button, simply unplug the router and plug it back in after waiting for around ten seconds. You can also try turning on airplane mode for a few seconds before connecting to the internet. If possible, move closer to the router before trying out the fixes below.

Solution 1: Forget and reconnect to your network

If restarting your router does not work, remove the network from the list of saved networks in your computer and then reconnect to it.

  1. Open the Windows Settings app using the Win + I shortcut and then click on 'Network and Internet' on the left.
  1. On the Network and Internet page, click on 'Wi-Fi.
  1. Now click on the 'Manage known networks' option.
  1. Then click on the 'Forget' button next to your Wi-Fi network.
  1. Once your system forgets the network, click on the Wi-Fi icon in the taskbar and then reconnect to it by typing in your password. Hopefully, this should resolve all network-related issues.

Solution 2: Keep your network connection in private mode

When Windows 11 connects to a Wi-Fi network, it automatically selects 'Public' Mode, which prevents it from being discoverable on the network and ensures privacy. However, sometimes, it can lead to connectivity issues, which can be resolved by changing the connection to private mode.

When your PC connects in the private mode, it becomes discoverable on the network and the file and printer sharing options are also enabled. You can use this mode while on a trusted network, but when you connect to a public network, it is better to switch back to the public mode. To switch to the private mode,

  1. Open the Wi-Fi page from the Windows Settings app as in the previous fix.
  2. Click on your Wi-Fi network to select it from the list of available connections.
  1. In the 'Network profile type' section, select 'Private network'.

Solution 3: Update your network adapter drivers

If your network adapter has outdated or faulty drivers, your Wi-Fi connection may have problems. So, you may need to update the network drivers to fix the issue.

  1. Right-click on the Start button and click on 'Device Manager'.
  1. When the Device Manager opens, click on the 'Network adapters' section to expand it.
  1. When the list of drivers appears, right-click on your wireless adapter and then click on the 'Update driver' option.
  1. Next, click on 'Search automatically for drivers'.
  1. Windows will automatically search for drivers online, and if they are available, it will download and install them. You may need to restart your computer after the drivers are installed.

Solution 4: Reinstall network adapter drivers

You can also try removing and reinstalling your network adapter drivers, which can help resolve issues that are causing connectivity problems.

  1. Open the Device Manager, expand your network adapter, and right-click on it before clicking on 'Uninstall Device'.
  1. Then click on 'Attempt to remove the driver for this device' and then on the 'Uninstall' button.
  1. Once the driver is removed, reboot your PC and Windows will automatically download suitable drivers from the internet.
Note: You can also roll back your network drivers from here by clicking on the Properties option after right-clicking on the driver. Then go to the driver tab at the top and click on 'Roll back driver' to go back to the previous driver version if the newer one is causing problems.

Solution 5: Run the Network Adapter Troubleshooter

If you're running into network-related issues, you can try running the Network Adapter Troubleshooter to try and resolve them.

  1. Open the Settings app and type troubleshoot in the search box on the left.
  1. In the results that appear, click on 'Troubleshoot Other problems'.
  1. Now you will see a list of available troubleshooters. Click on the 'Run' button on the right of the 'Network and Internet' option.
  1. When the troubleshooter opens, follow the instructions on your screen to diagnose and fix any problems with your network.

Solution 6: Restart the WLAN AutoConfig Service

The WLAN AutoConfig Service in Windows is a background service that allows your computer to connect to a network. If the service stops working or is not running properly, your computer may keep disconnecting from your PC. In this case, you will have to restart the service.

  1. Open the 'Run' dialog box using the Win + R shortcut and type services.msc before pressing Enter.
  1. When the services utility opens, right-click on WLAN AutoConfig and then click on 'Restart'. Once the service restarts, you can try to reconnect to the network.

Solution 7: Change power management settings

Your power management settings may be set to turn off various devices to save power, including your network adapter. You can disable this setting and check whether that helps fix connectivity issues.

  1. Open the Device Manager and click on the Network Adapters section to expand it.
  2. Right-click your network adapter and click on 'Properties'.
  1. When the Properties dialog box opens, click on the Power Management tab and click on the 'Allow the Computer to Turn Off This Device to Save Power' option to disable it.
  1. Click on the 'OK' button and close the Device Manager.

Solution 8: Change network adapter power settings

Sometimes your computer's power plan may be responsible for connectivity problems and changing it might help get rid of them.

  1. Open the Start menu, type power, and click on 'Edit power plan'.
  1. In the power plan page that opens, click on 'Change advanced power settings'.
  1. When the 'Power Options' window appears, click on the 'Wireless Adapter Settings' to expand it.
  1. Next, click on 'Power Saving Mode' and you will see 'On battery' and 'Plugged in' options.
  1. Click on the dropdown menu next to the 'On battery' option and set it to 'Maximum Performance'. Then do the same for the 'Plugged in' option.
  1. Finally, click on the 'Apply' and then 'OK' buttons. Your computer's power plan should not cause any connectivity issues now.

Solution 9: Reset network settings

Resetting all your network settings to the defaults is another possible solution you can try to fix Windows disconnecting from the internet.

  1. Open the Network and Internet page in the Settings app on your PC.
  2. Click on 'Advanced Network Settings at the bottom'.
  1. Next, click on 'Network reset' and then on 'Reset now'.
  1. Once your network settings are reset, you will need to reconnect your computer to the network.

Solution 10: Reset the TCP/IP Stack

  1. Open the Start menu, type cmd and click on 'Run as administrator'.
  1. In the command prompt window, type ipconfig /flushdns and press Enter.
  1. After that, type netsh winsock reset catalog and netsh int ip reset one by one, pressing Enter after each command.
  2. Close the command prompt window and restart your PC.

Solution 11: Check the roaming aggressiveness level

The Roaming Aggressiveness feature lets your computer switch between different wireless networks depending on their strength. Make sure the aggressiveness is not set to 'high' as that will cause the network adapter to keep switching between different networks.

  1. Open the Run dialog box using the Win + R shortcut and type ncpa.cpl inside it before pressing Enter.
  1. Right-click on your connection and then click on 'Properties'.
  1. Then click on the 'Configure' button.
  1. In the Properties dialog box, click on the 'Advanced' tab at the top.
  1. In the Property section, click on 'Roaming Aggressiveness' and on the right side under the 'Value' section, select 'Medium'. Then click on the 'OK' button.
