A. Preparation Before Execution
Make sure you keep:
- Password WiFi/VPN
- Static IP configuration (if applicable)
- List of dedicated proxies used
- Close all apps that use the connection (Zoom, online games, etc)
B. Steps to Reset TCP/IP via Command Prompt (Admin)
1. Open Command Prompt Elevated
- Press Windows + X → Select Terminal (Admin)
- Or type cmd in the Start Menu → Right-click → Run as administrator
2. Execute Sequential Reset Commands
Run the following commands one at a time by pressing Enter after each:
netsh int ip reset C:\resetlog.txt
netsh winsock reset
ipconfig /flushdnsTechnical Explanation of Each Command:
| Command | Function | Impact |
| netsh int ip reset | Resets the entire TCP/IP stack to the default | – Delete custom IP – Restore default DHCP |
| netsh winsock reset | Fix the catalog socket API | – Fixed an application failure to connect error |
| ipconfig /flushdns | Clearing the local DNS cache | – Resolve the “DNS_PROBE_FINISHED_BAD_CONFIG” error |
3. Verify and Restart
- Check the log file in C:\resetlog.txt to see the changes
- A restart is mandatory for the change to take effect permanently
If the “Access Denied” error appears:
– Make sure the CMD is run as an admin
– Temporarily disable antivirus/firewall
2. Reset TCP/IP via Windows Settings (GUI)
For those of you who don’t feel comfortable using Command Prompt or typing manual commands, Windows 11 provides an easier way through the graphical interface (GUI). This feature is called Network Reset, which will automatically reset all network configurations, including TCP/IP, Winsock, and network adapters.
This method is perfect for general users who want a more intuitive process without the need to understand the technical command line.
A. Step by Step Reset TCP/IP via Windows Settings (GUI)
1. Open Network Reset Utility
- Windows + I → Network & Internet → Advanced network settings
- Scroll down → Click Network reset
2. Confirm the Reset
- Click Reset now → Yes on the confirmation pop-up
- The system will be automated:
- Uninstall and reinstall network adapters
- Restore all network components to the default
3. Process Completion
- The PC will automatically restart in 5 minutes
- After the reboot:
- Reconnect to WiFi (enter password again)
- Reconfigure VPN if used
B. Fundamental Differences with the CMD Method
| Aspects | CMD Method | GUI Method |
| Level Reset | TCP/IP stack only | All network components |
| Restart Needs | Manual | Automatic |
| Impact | At least | More extensive (including drivers) |
| For Cases | Specific TCP/IP errors | Complex network problems |
The GUI Method will remove all:
– Network profiles (WiFi, Ethernet)
– VPN configurations
– Adapter-specific settings
– Backup first if there are special settings!
