How to Reset TCP/IP in Windows 11

This page is for the classic Windows 11 TCP/IP reset flow when a network adapter behaves strangely, addresses fail to renew, or normal reconnect steps do not help.

Start here

Start with the fastest command or direct open action

This block comes first on purpose. Copy one command, open PowerShell, Windows Terminal, Run, or Start search, paste the exact text, press Enter, then do the slower click-by-click checks underneath only if you still need them.

Reset the TCP/IP stack
Run this in: Command Prompt (Admin) or Windows Terminal Admin: Yes 
netsh int ip reset

What this command does

Resets core TCP/IP stack settings back toward the default Windows state.

What to do after running it

Wait for the command to finish completely, then restart or retest the same problem before making more changes.

Reset Winsock too
Run this in: Command Prompt (Admin) or Windows Terminal Admin: Yes 
netsh winsock reset

What this command does

Resets the Winsock catalog that Windows uses for socket and network communication.

What to do after running it

Wait for the command to finish completely, then restart or retest the same problem before making more changes.

Renew the IP address
Run this in: Command Prompt (Admin) or Windows Terminal Admin: Yes 
ipconfig /renew

Overview

What this guide helps you do

Resetting the TCP/IP stack can clear broken network settings layers that survive a normal disconnect or router reboot.

  • A restart matters after these commands.
  • This is stronger than simply disconnecting and reconnecting Wi‑Fi.
  • It is often paired with a DNS flush or adapter reset.

When to use this

When to use this guide

Useful when Windows 11 has odd local network behavior, limited connectivity, or adapter issues after updates, VPN software, or manual network changes.

Before you start

What to review first

This reset affects network stack settings. Save VPN details or unusual adapter settings first if you rely on them.

Do this exactly

Open the right Windows area first, then follow the changes one by one

  1. Press Start, type Terminal, right-click Windows Terminal, and choose Run as administrator so the network reset commands can write the changes they need.
  2. Type netsh int ip reset exactly and press Enter. Let the reset messages finish instead of closing the window early.
  3. Type netsh winsock reset and press Enter so Windows also rebuilds the Winsock catalog used by many network applications.
  4. Restart the PC. This is part of the repair flow, not an optional extra.
  5. After Windows comes back, reconnect to Wi‑Fi or Ethernet and test the same site, service, or adapter problem again before trying bigger network changes.

Exact click path

Tell the user exactly what to open and press

Do not change ten things at once. Open the exact Windows page first, make one clear change, then check whether it solved the problem before moving on.

Fast open: Press Start, type Terminal, right-click Windows Terminal, choose Run as administrator, then type the reset commands exactly as shown on this page. After both commands finish, restart Windows before you decide whether the network problem is fixed.

FAQ

Questions about How to Reset TCP/IP in Windows 11

Will this remove my Wi‑Fi password?

Usually no, but it can reset parts of the network stack and related settings. Save anything unusual first if you rely on custom network configuration.

Should I run both commands?

Yes, many Windows network repair flows use both the TCP/IP reset and Winsock reset together before the restart.
