Disable network adapter power saving setting

1. Open the Device Manager by pressing the Windows key + X and selecting “Device Manager” from the context menu.
2. Expand the “Network adapters” category and locate your wireless network adapter.
3. Right-click on the adapter and select “Properties” from the context menu.
4. In the Properties window, go to the “Power Management” tab.
5. Uncheck the box that says “Allow the computer to turn off this device to save power.”
6. Click “OK” to save the changes.
7. Restart your laptop for the changes to take effect.

By disabling the power saving setting, you ensure that your network adapter stays active and connected to your Wi-Fi network. This can help prevent intermittent disconnections and improve overall stability.

Update network driver

1. Update your network driver: Sometimes, outdated network drivers can cause your laptop to keep disconnecting from Wi-Fi. To fix this issue, you can update your network driver to the latest version. Here’s how:

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 network adapter and select “Update driver.”
4. Choose the option to search automatically for updated driver software.
5. Follow the on-screen instructions to complete the driver update process.

Updating your network driver can help resolve compatibility issues and improve the stability of your Wi-Fi connection. If the issue persists, you can also try uninstalling the network driver and then reinstalling it.

python
import subprocess

def check_internet_connection():
try:
# Ping a reliable website to check if internet is accessible
subprocess.check_output(["ping", "-c", "1", "www.google.com"])
return True
except subprocess.CalledProcessError:
return False

if __name__ == "__main__":
if check_internet_connection():
print("Your laptop is connected to the internet.")
else:
print("Your laptop is not connected to the internet.")

This sample code attempts to determine if your laptop is connected to the internet by pinging a reliable website (in this case, www.google.com). If the ping is successful, it returns True; otherwise, it returns False.

Change Scan Valid Interval

If your laptop keeps disconnecting from Wi-Fi, you may need to adjust the scan valid interval. This setting determines how often your laptop scans for available wireless networks. Here’s how to change it:

1. Open the Start menu and type “Device Manager” in the search bar. Open the Device Manager app.
2. Expand the “Network adapters” section and find your wireless network adapter.
3. Right-click on the adapter and select “Properties.”
4. In the Properties window, go to the “Advanced” tab.
5. Look for a setting called “Scan Valid Interval” or something similar. This setting may vary depending on your adapter.
6. Double-click on the setting to edit it.
7. Change the value to a higher number, such as 120 or 180. This will increase the interval between scans.
8. Click “OK” to save the changes.
9. Restart your laptop to apply the new setting.

By adjusting the scan valid interval, you can improve the stability of your Wi-Fi connection and prevent frequent disconnections. Keep in mind that changing this setting may slightly increase the time it takes for your laptop to connect to a new network.

If you continue to experience Wi-Fi issues, consider updating your device drivers, checking for any software conflicts, or contacting your internet service provider for further assistance.

Repair corrupted system files

If you’re experiencing frequent disconnections from your Wi-Fi network on your laptop, it could be due to corrupted system files. Corrupted files can cause various issues with your computer’s performance, including network connectivity problems.

To repair corrupted system files, follow these steps:

1. Open the Command Prompt as an administrator. You can do this by pressing the Windows key, typing “cmd,” right-clicking on Command Prompt, and selecting “Run as administrator.”

2. In the Command Prompt window, type the following command and press Enter: sfc /scannow. This command will scan your system for corrupted files and attempt to repair them.

3. Wait for the scan to complete. It may take some time, so be patient.

4. If the scan finds any corrupted files, it will attempt to repair them automatically. If it’s unable to repair them, you may need to perform additional troubleshooting steps or consult a professional.

5. Once the scan is complete, restart your computer and check if the Wi-Fi disconnection issue persists.

Repairing corrupted system files can often resolve network connectivity issues on your laptop. If you’re still experiencing problems, it may be worth checking other potential causes, such as your internet service provider, router settings, or device drivers.

Remember to keep your system up to date with the latest patches and updates from Microsoft, as these can also help prevent network connectivity problems.

Check for old router or outdated software

One common reason why your laptop keeps disconnecting from WiFi is due to an old router or outdated software. To fix this issue, follow these steps:

1. Check if your router is outdated. If you’ve had your router for a long time, it may not be compatible with newer devices or have the latest security features. Consider upgrading to a newer model.

2. Update your router’s firmware. Manufacturers often release firmware updates to fix bugs and improve performance. Visit the manufacturer’s website and download the latest firmware for your router model. Follow the instructions provided to update the firmware.

3. Check for software updates on your laptop. Outdated network drivers can cause connectivity issues. Go to the manufacturer’s website or use the device manager on your laptop to check for updates. Install any available updates for your network adapter.

4. Restart your router and laptop. Sometimes, a simple restart can resolve connectivity issues. Turn off your router, wait for a few seconds, and then turn it back on. Also, restart your laptop to refresh network settings.

5. Reset your router to factory settings. If all else fails, you can try resetting your router to its default settings. Keep in mind that this will erase all custom settings, so make sure to note them down before proceeding. Consult your router’s manual or manufacturer’s website for instructions on how to perform a factory reset.

By checking for an old router or outdated software and following these steps, you can resolve the issue of your laptop constantly disconnecting from WiFi.
