This article will thoroughly analyze the common causes of network adapter disconnections and provide a detailed step-by-step guide to help you resolve the issue and restore a stable internet connection.
I. Common Causes of Frequent Network Adapter Disconnections
Outdated or corrupted network adapter drivers
Power management settings causing automatic shutdown
Weak or heavily interfered wireless signal
Router or network equipment failure
System updates or software conflicts
II. Detailed Troubleshooting Steps
1. Update the Network Adapter Driver
Outdated or damaged drivers are a major cause of persistent disconnection. Ensuring that your network adapter driver is up to date can effectively resolve this issue. To avoid installation errors, it is recommended to use Driver Talent X to scan and automatically update all drivers with one click, ensuring compatibility and up-to-date versions.
Click the button below to download the latest version of Driver Talent X, install and launch the software.
In the "Drivers" section, select "Scan" and click the "Scan" button. The software will automatically detect the status of all drivers on your computer.
Locate the network driver in the scan results and click the "Upgrade" button.
After the update is complete, restart your computer to ensure the driver takes effect.
2. Disable Power Management to Prevent Auto Shut-off

Right-click your network adapter device and select "Properties".
Switch to the "Power Management" tab.
Uncheck the option "Allow the computer to turn off this device to save power".

3. Optimize Wireless Network Environment
Place the router in an open area, avoiding obstructions from walls or metal objects.
Log in to the router's control panel (usually 192.168.1.1 or 192.168.0.1).
Go to the wireless settings and change the wireless channel to one with less interference (such as 1, 6, or 11).
Use your computer to check Wi-Fi signal strength and ensure it is stable.
4. Restart Network Devices
Power off the modem and router, then wait 1–2 minutes.
Turn on the modem first, wait for it to fully boot up, then power on the router.
