How to fix common network problems after update on Windows 10

If a quality update breaks the network connection, you can follow some basic troubleshooting steps to resolve the problem quickly.

Reboot computer

Although it might be obvious, it's not for everyone. Typically, a simple reboot can fix most common problems, including problems connecting to the network and the internet.

To restart a device, use these steps:

1. Open Start.
2. Click the Power option.
3. Select the Restart option.

Once you complete the steps, open the web browser and confirm the internet is working, loading a website upon restart.

If the network icon in the notification area shows an active connection, but you cannot open a particular website, try to load a different site as the problem could be with the website. You can also try using a different browser to confirm the problem is not the application.

Confirm network settings

The next step involves using command lines to confirm the problem is not something happening between the device and the router.

To check if the Windows 10 network configuration is working, use these steps:

1. Open Start.
2. Search for Command Prompt and click the top result to open the console.
3. Type the following command to find out the IP address of the router and press Enter:ipconfig

6. Confirm successful replies without packet loss in the output.

After you complete the steps, if the "Packets" field returned with "4" successful replies, the router's connection is working, indicating that the problem could lie in the connection between the router and ISP. Or it could be the case that the ISP is currently experiencing issues.

If you can access the internet from your phone or another computer connected to the same network, then the problem could be the device in question.

Enable Wi-Fi interface

If there is no connection to the internet, the wireless interface may not be enabled.

To check and enable a Wi-Fi interface, use these steps:

1. Open Settings.
2. Click on Network & Internet.
3. Click on Wi-Fi.
4. Turn on the Wi-Fi toggle switch.
