Resolving Unreliable Wi-Fi Connectivity on a Windows PC: A Comprehensive Troubleshooting Guide
Introduction
Experiencing inconsistent Wi-Fi connections can be frustrating, especially when your other devices connect seamlessly. If you’re facing issues such as intermittent connectivity, “Can’t reach DNS server” errors, or “No internet, secured” messages on your Windows PC, you’re not alone. This article provides a professional, step-by-step approach to diagnosing and resolving these common connectivity problems, ensuring a more stable and reliable internet experience.
Understanding the Issue
Many users report that their PC exhibits inconsistent Wi-Fi behavior—sometimes connecting flawlessly, other times failing to connect for hours. Notably, these issues often occur independently of the router or other devices, indicating that the problem lies within the PC’s network configuration or hardware.
Common Symptoms:
– Intermittent connectivity
– “Can’t reach DNS server” errors
– “No internet, secured” notifications
– Inability to connect after rebooting or start-up
Preliminary Troubleshooting
Before diving into complex solutions, consider these basic checks:
– Confirm that your Wi-Fi network is functioning correctly by testing other devices; if they connect without issues, the problem is likely confined to your PC.
– Restart your PC and router to reset network states.
– Ensure airplane mode is off and Wi-Fi is enabled on your PC.
– Verify that your Wi-Fi password is correct and that you are connecting to the right network.
Advanced Troubleshooting Steps
- Reset Network Stack and DNS Settings
Resetting the network stack can resolve configuration issues causing connectivity problems.
- Open Command Prompt as Administrator:
- Click Start, type “cmd,” right-click on “Command Prompt,” and select “Run as administrator.”

Restart your computer and check if the issue persists.
