Some Windows 10 users may encounter network disconnection errors during use, which can prevent them from connecting to the internet or cause frequent drop-offs. This article will introduce several common and effective methods to help you quickly fix the issue and restore a stable network connection.

1. Update Network Adapter Drivers

Outdated or corrupted network drivers are often the root cause of network disconnection errors. To ensure that your network adapter functions properly, it is recommended to update drivers regularly. Driver Talent is a recommended tool to automatically detect and update drivers, saving time while avoiding the risk of downloading or installing incorrect drivers.

Download Driver Talent

Click the download button to get the latest version of Driver Talent, install the software, and open it. Click "Scan".
After scanning, the software will display which drivers are missing or need updating. Find the network adapter driver in the list and click the "Update" button.

After the update is complete, it is recommended to restart your computer to ensure the updated drivers take effect.

2. Check Network Hardware

Check the Router and Modem: Ensure that both your router and modem are powered on and that all indicator lights are functioning properly. If other devices can connect to the network, the issue is likely with the computer.
Restart the Router: Sometimes, routers may encounter issues due to extended uptime or network congestion. You can try unplugging the router's power cable, waiting for 1-2 minutes, and plugging it back in.

Right-click on the Start menu and select "Device Manager".

Expand "Network Adapters", find the network adapter you're using.

Right-click the adapter and select "Disable Device".
