To reset the TCP/IP stack in Windows 11, use the Netsh command in Command Prompt (Admin) by running "netsh int ip reset" and optionally "netsh winsock reset", then restart your computer; alternatively, use the GUI method via Settings > Network & internet > Advanced network settings > Network reset > Reset now, which removes and reinstalls network adapters; this process reinstalls the TCP/IP protocol, restores default IP settings, and clears corrupted configurations, helping resolve internet connectivity issues, DNS problems, or connection drops, and is safe with no impact on hardware, though Wi-Fi passwords are lost in the GUI method.
Resetting the TCP/IP stack in Windows 11 can help resolve various network connectivity issues, such as inability to access the internet, intermittent connection drops, or DNS-related problems. The TCP/IP stack is responsible for managing network communications, and resetting it restores the network protocols to their default state.

Here’s how to reset the TCP/IP stack in Windows 11:
1. Use the Netsh Command in Command Prompt (Admin)
This is the most common and effective method.

-
Open Command Prompt as Administrator
- Press
Win S
, type cmd. - Right-click on Command Prompt and select Run as administrator.
- Click Yes if prompted by User Account Control (UAC).
- Press
-
Run the Reset Command
Type the following command and press Enter:netsh int ip reset
- This command resets the IPv4 and IPv6 TCP/IP stack to default settings.
Optional: Reset Winsock as well
If you're still having issues, also reset Winsock:netsh winsock reset
Restart Your Computer
After running the commands, restart your PC for the changes to take effect.
? Tip: You can combine both resets in one go:
netsh int ip reset && netsh winsock reset
2. Use Network Reset (GUI Method)
If you prefer using the graphical interface, Windows 11 offers a built-in network reset option that includes resetting the TCP/IP stack.
- Go to Settings (
Win I
)- Navigate to Network & internet > Advanced network settings
- Scroll down and click Network reset
- Click Reset now, then confirm
?? Note: This will remove and reinstall all network adapters and reset networking components (including Wi-Fi passwords), so you’ll need to reconnect to networks afterward.

- Restores default IP addressing settings
- Clears custom or corrupted configurations
- Does not affect your Wi-Fi or Ethernet hardware, but may temporarily disconnect you
It’s safe to run and often fixes issues caused by misconfigurations, malware, or failed updates.
When Should You Reset TCP/IP?

- You can’t connect to the internet despite being connected to Wi-Fi or Ethernet
- Websites won’t load, but other devices on the same network work fine
- You’re getting errors like “No internet, secured” on Wi-Fi
