In Windows 10, slow internet speed is a common issue. This article provides a series of effective solutions to help you fix the problem and restore smooth network connectivity.
1. Check Hardware Connections
Ensure that the Ethernet cable is securely connected and that the router and modem are functioning properly.
Disconnect and reconnect the cable or wireless adapter to confirm there are no hardware issues.
Try plugging the cable into different ports on the router or computer, or test with a spare cable to check the connection quality.
2. Update Network Adapter Drivers

It is recommended to use Driver Sentry to automatically detect and update drivers, saving time and avoiding the risk of downloading or installing incorrect drivers.
Click the download button to get the latest version of Driver Sentry, install it, and then open the software.

After the scan, locate the network adapter driver in the results list and click "Upgrade".
After updating, restart your computer to ensure the updated drivers take effect.
