How to disable TCP/IPv6 (IPv6) on Windows 11

IPv6 is the next-generation internet protocol, but not every network or device plays nice with it yet. If you’re having connectivity issues, or you just need to turn it off for troubleshooting, here’s how you can quickly disable IPv6 (TCP/IPv6) on your Windows 11 PC.

Method 1: Disable IPv6 via Network Adapter Settings

1. Open Settings
   Press Windows + I to open the Settings app.
2. Go to Network & Internet
   Select Network & Internet from the sidebar.
3. Open Advanced Network Settings
   Scroll down and click Advanced network settings.
4. Select Your Network Adapter
   Under “Related settings,” click More network adapter options. This opens the Control Panel window.
5. Open Adapter Properties
   Right-click your active network connection (Wi-Fi or Ethernet) and choose Properties.
6. Uncheck Internet Protocol Version 6 (TCP/IPv6)
   In the list, find Internet Protocol Version 6 (TCP/IPv6) and uncheck the box next to it.
7. Click OK
   Click OK to save your changes.
8. Restart Your Computer
   For best results, reboot your PC.

Method 2: Disable IPv6 Using PowerShell (Advanced)

If you prefer using commands, PowerShell makes it even faster:

1. Open PowerShell as Administrator
   Search for “PowerShell” in the Start menu, right-click it, and select Run as administrator.
2. Run This Command:
   Disable-NetAdapterBinding -Name "*" -ComponentID ms_tcpip6
   • This command disables IPv6 on all network adapters.
   • To disable IPv6 on a specific adapter, replace * with the adapter’s name.
3. Restart Your Computer
   Restart to apply the changes.

Quick Note

• Disabling IPv6 may be required for older software, VPNs, or some routers.
• Only disable IPv6 if you have a specific reason—most home users can leave it on.

That’s it. IPv6 will now be disabled on your Windows 11 PC. If you want to enable it again, just follow the same steps and re-check the IPv6 box, or run:

Enable-NetAdapterBinding -Name "*" -ComponentID ms_tcpip6
