Whether you're using Wi-Fi or a wired network, network adapter issues can lead to no internet access. This article provides several methods to fix the problem and restore your connection quickly.

1. Check Physical Connections

Ensure the Ethernet cable is securely connected to both the computer's Ethernet port and the router's LAN port.

Unplug the router and modem, wait 30 seconds, and then plug them back in to resolve temporary network connection issues.

If you suspect a faulty cable, try using a different Ethernet cable.

If you're using Wi-Fi, check if the Wi-Fi switch is on and confirm you're connected to the correct network.

2. Update Network Adapter Drivers

Outdated or faulty network adapter drivers can cause connectivity issues. Regularly updating your drivers can improve network stability and performance. It's recommended to use Driver Sentry to automatically detect and update drivers, saving time and reducing the risk of downloading or installing incorrect drivers.

Download

Click the download button to get the latest version of Driver Sentry. After installation, open the software and click "Scan".
