2. Update drivers: Outdated or faulty device drivers can sometimes cause high CPU usage. Visit the manufacturer’s website or use Windows Update to ensure all drivers are up to date.

3. Disable unnecessary network adapters: If you have multiple network adapters installed, try disabling the ones you’re not using to see if it reduces the CPU usage.

4. Disable WLAN AutoConfig service: This service is responsible for managing wireless connections and can sometimes cause high CPU usage. To disable it, open the Services application by pressing Win+R, typing “services.msc,” and pressing Enter. Locate the WLAN AutoConfig service, right-click it, and select Properties. Change the Startup type to Disabled and click OK.

5. Apply latest Windows updates: Microsoft regularly releases updates that include bug fixes and performance improvements. Make sure your Windows 10 is up to date by going to Settings > Update & Security > Windows Update.

Updating Device Drivers to Fix Wlanext.exe High CPU Usage

Updating your device drivers can help resolve Wlanext.exe high CPU usage on Windows 10. Follow these steps to update your drivers:

1. Open the Device Manager by pressing the Windows key + X and selecting “Device Manager” from the menu.
2. In the Device Manager window, expand the “Network adapters” category.
3. Right-click on your wireless network adapter and select “Update driver.”
4. Choose the option to search automatically for updated driver software.
5. Windows will search for the latest drivers and install them if available.
6. Restart your computer to apply the changes.

If updating the drivers doesn’t resolve the issue, you can try reinstalling the drivers. Here’s how:

1. Open the Device Manager again.
2. Right-click on your wireless network adapter and select “Uninstall device.”
3. Confirm the uninstallation and then restart your computer.
4. After the restart, Windows will automatically reinstall the driver for your wireless network adapter.

If the problem persists, you may need to visit the manufacturer’s website and download the latest driver from there. Make sure to choose the driver that is compatible with your specific device model and Windows version.

Updating your device drivers can help ensure that your system is running smoothly and efficiently. It is a crucial step in troubleshooting various issues, including high CPU usage caused by Wlanext.exe.

python
import psutil

if high_cpu_processes:
print("Processes with high CPU usage:")
for process in high_cpu_processes:
print(f"PID: {process['pid']}, Name: {process['name']}, CPU Percent: {process['cpu_percent']}")
else:
print("No processes found with high CPU usage.")


This code utilizes the `psutil` library, which provides an interface to retrieve information about running processes on a system. The `get_high_cpu_processes` function takes a threshold value as input and returns a list of processes with CPU usage above that threshold. The sample code then demonstrates how to use this function to identify and display processes with high CPU usage.

Checking Antivirus Software for Wlanext.exe Issues

If you are experiencing high CPU usage due to the wlanext.exe process on your Windows 10 computer, one possible cause could be a conflict with your antivirus software. To check if this is the case and resolve the issue, follow these steps:

1. Open your antivirus software by clicking on its icon in the system tray or by searching for it in the Start menu.

2. Look for any settings or options related to real-time scanning or active protection. These settings are usually found in the antivirus software’s main dashboard or settings menu.

3. Disable the real-time scanning or active protection temporarily. This will prevent the antivirus software from constantly scanning and monitoring files in the background.

4. Once the real-time scanning or active protection is disabled, monitor your CPU usage using the Task Manager. Press Ctrl + Shift + Esc to open the Task Manager, then go to the “Processes” tab.

5. Look for the wlanext.exe process in the list of running processes. If the CPU usage drops significantly or returns to normal after disabling the real-time scanning, it is likely that the antivirus software was causing the issue.

6. To permanently resolve the issue, you may need to add an exception or exclude the wlanext.exe file from being scanned by your antivirus software. Consult your antivirus software’s documentation or support resources for instructions on how to do this.

7. After adding the exception or excluding the wlanext.exe file, re-enable the real-time scanning or active protection in your antivirus software.

By checking your antivirus software for wlanext.exe issues and adjusting its settings accordingly, you can resolve high CPU usage problems on your Windows 10 computer and ensure smooth performance.

Troubleshooting Wlanext.exe High CPU Usage with Network Settings

To resolve this, you can try the following steps:

1. Restart your computer: Sometimes, a simple restart can resolve temporary issues with processes consuming high CPU usage.

2. Update your device drivers: Outdated or incompatible drivers can cause high CPU usage. Visit the manufacturer’s website for your network adapter and download the latest drivers.

3. Disable unnecessary network adapters: If you have multiple network adapters installed on your computer, disabling the ones you are not using can help reduce CPU usage.

4. Reset your network settings: Resetting your network settings can resolve any configuration issues that may be causing the high CPU usage. Open the Command Prompt as an administrator and run the following commands one by one:
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns
