Troubleshooting Guide: Resolving Ethernet Connectivity Issues on Your PC

Introduction

A stable internet connection is vital for productivity, entertainment, and communication. However, many users encounter frustrating scenarios where their PC is connected to Ethernet or Wi-Fi networks yet cannot access the internet. If you find yourself in such a situation, this comprehensive guide will help you diagnose and resolve the issue efficiently.

Understanding the Problem

Common symptoms include:

• The network icon indicates a connection to Ethernet or Wi-Fi.
• Internet access is unavailable despite the connection status.
• Local network access (e.g., shared files) may still work, but web browsing fails.
• The problem persists across multiple networks or only affects a specific network.

Initial Steps to Diagnose the Issue

1. Verify Physical Connections

2. Ensure Ethernet cable is securely plugged into your PC and router.

3. Check for visible damage to the cable; replace if necessary.

4. If using Wi-Fi, confirm your device is connected to the correct network.

5. Confirm Network Status

6. On Windows, navigate to Settings > Network & Internet > Status.

7. Check if it reports connected to the network and “Internet access” is confirmed.

8. On Linux or Mac, use system network tools to verify connection status.

9. Test Other Devices

10. Since your other devices (like your laptop) access the internet without issues, this points toward an issue localized to your PC.
