When your internet suddenly stops working or becomes extremely slow on your Windows PC, it doesn’t always mean your router or ISP is the problem.

In many cases, the issue comes from corrupted network settings inside Windows itself.

Before calling support or restarting your router 10 times, try this simple fix: a full Windows network reset using 7 Windows Commands.

These commands reset your network stack at the software level and solve the most common connection issues.

How to Open the Command Terminal

First, you need to open an administrator terminal:

• Right-click the Windows Start button
• Click Terminal (Admin)

This opens PowerShell or Command Prompt with full permissions.

Now run the commands one by one.

Command 1: Flush DNS Cache

ipconfig /flushdns

ipconfig /flushdns

This clears your DNS cache, a local memory of website addresses.

If it becomes outdated or corrupted, websites may stop loading even when your internet is working.

Command 2: Release Your IP Address

ipconfig /release

ipconfig /release

This disconnects your PC from the network at the IP level.

You will temporarily lose internet; this is normal.

Command 3: Renew Your IP Address

ipconfig /renew

ipconfig /renew

This requests a fresh IP address from your router.

It fixes issues like IP conflicts or broken DHCP assignments.

Command 4: Reset Winsock

netsh winsock reset

netsh winsock reset

This resets the Windows networking catalog used by all apps.

It is one of the most powerful fixes for cases where:

• Internet shows connected, but nothing loads
• Apps fail to connect
• Browsers stop working

Command 5: Reset TCP/IP Stack

netsh int ip reset

netsh int ip reset

This restores the core network settings of Windows to default.

It fixes issues caused by misconfigurations, VPNs, or third-party tools.

Command 6: Reset TCP Settings

netsh int tcp reset

netsh int tcp reset

This resets advanced TCP settings like connection handling and timeouts.

It helps fix unstable or inconsistent connections.

Command 7: Reset Windows Firewall

netsh advfirewall reset

netsh advfirewall reset

This restores Windows Firewall to default settings.

It removes any broken or overly strict rules that may block internet traffic.

Final Step: Restart Your PC

Once all commands are complete, restart your computer.

This step is very important because several of these changes only take full effect after a reboot.

After Restart

Test your internet connection:

• Open a browser
• Visit multiple websites
• Try apps that were not working

In most cases, your connection will be fully restored.

If the Problem Still Exists

If your internet still doesn’t work after this:

The issue is likely not Windows anymore.

Check:

• Ethernet cable
• Router ports
• Network driver updates
• Other devices on the same network

If all devices are affected, the issue is probably your router or ISP.

Final Thoughts

This 7-command sequence is one of the most effective Windows network resets you can do.

It takes less than 2 minutes, and it solves a large number of “connected but no internet” problems without technical tools.
