You upgrade Windows 8 to the latest version of Windows 10. But Laptop cannot connect to the wireless network (WiFi). After fighting hard to install the latest driver files for network adapters, we can finally connect to the internet via WiFi. But the process of connecting laptop Wifi is continuously disconnected when using.

In this article we want to share all the things we tried to solve the WiFi connection problem.

No Internet connection - Network adapter problem

When you notice that your computer cannot connect wirelessly after upgrading Windows 10, the most likely reason is the network adapter. Follow the steps below to fix this problem:

  • Right-click the "Start" menu and select "Device Manager" or use the "Cortana" search box next to the "Start" menu and open "Device Manager".
  • Find the adapter used on your computer in the "Network adapters" section.

  • In our case it is "Intel (R) PRO / Wireless 3945ABG". Visit the provider page and download the latest driver file for Windows 10.
  • Uninstall old drivers and install newly downloaded drivers.
  • Click on "Scan for hardware changes" to re-enable the adapter with the newly installed driver.

This will solve the problem of connecting to a wireless network.

Turn off Airplane Mode

Windows 10 has an option to turn off wireless connectivity by using "Airplane Mode" quickly. Click on the tray WiFi icon and check your "Airplane Mode" is turned off.

Common Off WiFi connection

It took a few days to realize that the WiFi connection had dropped frequently due to a problem in the laptop. Since we use VPN, it is doubtful first and the router is second. When the same VPN and router completely work with the iPhone, we were forced to look at Windows laptops to look for clues. When looking at "Events Viewer", it confirms that the network has been permanently abandoned with a "WLAN AutoConfig service failed to connect to a wireless network" error message.

Disable Network Discovery

Open the "Network and Sharing Center" and click the wireless internet connection you are using.

Clicking the "Wireless Properties" button in the "General" section will take you to the properties of your wireless connection. Disable the "Look for other wireless networks while connecting to this network" option under the "Connection" tab.

Power Management installation

Open the "Network and Sharing Center" and click on your wireless connection name. This time click the "Properties" button in the "Activity" section.

You will be taken to the "Wi-Fi Properties" pop-up window and click the "Configure" button to connect your wireless router. The next pop-up window will display the network connection properties of your wireless router and disable the option "Allow the computer to turn off this device to save power" in the "Power Management" tab.

Option 3 - Disable IPv6

IPv6 address was introduced with IPv4 address exhaustion and now both IPv4 and IPv6 are used by most services. You can try it by turning off IPv6 connectivity under your "Power Management".

4 - Restart the computer browser service

Right click on the Windows task bar and click on the "Task Manager" option. By default, "Browser" services that will be in "Running" can be seen in the "Services" tab. Right-click on the "Browser" and "Restart" services.


Restart the computer browser service

Option 5 - Tun off Bluetooth Discovery Mode

If you have Bluetooth enabled on your laptop, navigate to Bluetooth settings and click "More Bluetooth options". Then disable the "Allow Bluetooth devices to find this PC" option in the "Discovery" section.

We have reviewed all of the popular Microsoft forums and other popular forums and it is clear that the wireless connection problem is something to do with Windows and not related to routers. Unfortunately, this issue is not resolved by any appropriate solution. Although option 2 worked for us, you may need to try different options for stable WiFi connection.
