Checking For and Resolving Networking Issues on a Local Windows 11 PC

Networking issues can significantly impact your productivity and online experience. This comprehensive guide will help you diagnose and resolve networking problems on a Windows 11 PC, covering both IPv4 and IPv6. We will explore solutions using the GUI, Command Line, and PowerShell commands.

Networking issues can arise from various sources, such as incorrect configurations, outdated drivers, or hardware failures. By systematically diagnosing the problem, you can restore your network connectivity. This guide will cover methods to check and resolve issues for both IPv4 and IPv6 configurations.

Checking Network Connectivity

Using the GUI

  1. Open Network & Internet Settings:
  • Right-click the network icon in the system tray and select “Network & Internet settings.”
  • Alternatively, go to Settings > Network & Internet.
  1. Check Network Status:
  • In the “Status” section, you can see the current network connection status. If there are issues, it will indicate “No Internet access” or similar messages.
  1. View Network Properties:
  • Go to “Advanced network settings” and select “Network and Sharing Center.”
  • Click on your network connection to view details like IPv4 and IPv6 addresses, DNS servers, and more.

Using Command Line

  1. Open Command Prompt:
  • Press Win + X and select “Command Prompt (Admin)” or “Windows Terminal (Admin).”
  1. Check IP Configuration:
  • Run ipconfig to view the current IP configuration for all network adapters.
  • To see detailed information, use ipconfig /all.
  1. Ping to Check Connectivity:
  • Use ping <IP address> to test connectivity to a specific IP address.
  • Example: ping to check connectivity to Google’s DNS server.

Using PowerShell

  1. Open PowerShell:
  • Press Win + X and select “Windows PowerShell (Admin)” or “Windows Terminal (Admin).”
  1. Check IP Configuration:
  • Run Get-NetIPAddress to view IP address information for all network adapters.
  1. Test Network Connectivity:
  • Use Test-Connection <IP address> to test connectivity.
  • Example: Test-Connection

Diagnosing Common Network Issues

IP Configuration Issues

  1. Check for Correct IP Assignment:
  • Ensure your PC is receiving a proper IP address from the router.
  • Run ipconfig or Get-NetIPAddress to check the IP address, subnet mask, and default gateway.
  1. Renew IP Address:
  • In Command Prompt, run ipconfig /release followed by ipconfig /renew.
  1. Check for IP Conflicts:
  • Ensure no other device on the network has the same IP address.

DNS Issues

  1. Check DNS Server Configuration:
  • Use ipconfig /all to see DNS server addresses.
  • Ensure the DNS servers are correctly configured.
  1. Test DNS Resolution:
  • Run nslookup <domain> to test DNS resolution.
  • Example: nslookup

Network Adapter Issues

  1. Check Network Adapter Status:
  • Go to Device Manager (press Win + X and select “Device Manager”).
  • Expand “Network adapters” and ensure there are no warning signs.
  1. Reset Network Adapter:
  • Disable and re-enable the network adapter in Device Manager.

Resolving Network Issues

Resetting the Network

  1. Network Reset:
  • Go to Settings > Network & Internet > Advanced network settings.
  • Scroll down and select “Network reset.” This will reset all network adapters and restore network settings to default.

Flushing DNS Cache

  1. Flush DNS Cache:
  • Open Command Prompt as Admin.
  • Run ipconfig /flushdns.

Updating Network Drivers

  1. Update Network Drivers:
  • Go to Device Manager.
  • Right-click your network adapter and select “Update driver.”
  • Choose “Search automatically for updated driver software.”

Advanced Troubleshooting

Using Network Troubleshooter

  1. Network Troubleshooter:
  • Go to Settings > Network & Internet > Status.
  • Click on “Network troubleshooter” and follow the prompts to diagnose and fix network issues.

Analyzing Network Traffic

  1. Use Wireshark:
  • Download and install Wireshark.
  • Capture network traffic to analyze detailed packet-level information.

Helpful Tips

  • Keep Drivers Updated: Regularly update network drivers to ensure compatibility and performance.
  • Check Router and Modem: Sometimes the issue may lie with your router or modem. Restart them if needed.
  • Use Wired Connection: For troubleshooting, use a wired Ethernet connection to rule out Wi-Fi issues.
  • Disable Firewall Temporarily: Sometimes, firewalls can block network access. Temporarily disable it to check if it’s the cause.


By following the steps outlined in this guide, you can effectively diagnose and resolve network issues on your Windows 11 PC. Whether using the GUI, Command Line, or PowerShell, these methods cover a wide range of potential problems and solutions. Regular maintenance and updates can help prevent future networking issues and ensure a stable and fast internet connection.
