Troubleshooting Internet Connectivity Issues on a Newly Built PC: Connectivity Loss After Shutdown

Building a new PC is an exciting milestone, but it can sometimes come with unexpected challenges. One common issue newcomers encounter is losing internet connectivity after shutting down and restarting their system, despite appearing connected to Wi-Fi. If you’re experiencing a situation where all applications indicate an active internet connection, yet websites fail to load, this guide will help you diagnose and resolve the problem effectively.

Understanding the Scenario

Let’s consider a typical case: After assembling a new PC, the user notices that although Wi-Fi shows as connected, web browsers and other applications cannot reach the internet. The connection appears stable, but network activity is non-functional. Restarting the computer temporarily restores browser functionality, but the issue reoccurs shortly thereafter.

Potential Causes

Several factors can cause such issues, especially in newly built systems. Common culprits include:

• Network Adapter Driver Issues
• Software Conflicts (e.g., VPNs or third-party security software)
• Network Settings Misconfiguration
• Firewall or Antivirus Interference
• Hardware Problems with the Network Interface Card (NIC) or Wi-Fi Adapter

Step-by-Step Troubleshooting Guide

1. Verify Physical and Hardware Connections
2. Ensure your Wi-Fi adapter is properly installed and seated.

3. If using a USB Wi-Fi dongle, try reconnecting or testing on another port.

4. Check Network Status and IP Configuration

5. Open Command Prompt and run:

bash
ipconfig /all

• Confirm that your network adapter has a valid IP address and DNS servers assigned.

• Reset Network Settings

• In Windows 11, navigate to Settings > Network & Internet > Advanced network settings > Network reset.

• Click ‘Reset now’ and restart your PC.

• Update or Reinstall Network Drivers

• Visit the motherboard manufacturer’s website (in this case, ASUS Prime B760M-A WiFi) and download the latest network drivers.

• Alternatively, in Device Manager:

  • Locate your Network Adapter
  • Right-click and select ‘Update driver’
  • Choose ‘Search automatically for drivers’ or manually install the latest drivers.

• Disable VPNs and Security Software Temporarily

• VPNs can sometimes interfere with local network configurations.
• Disable any VPNs and test connectivity.

• Also, temporarily disable antivirus and firewall to see if they are blocking network access.

• Check Firewall
