How to Reset the Entire Network Stack on Windows 11 in One Command

Quick fix: Open Settings → Network & internet → Advanced network settings → Network reset and click Reset now — one button reinstalls every network adapter, clears all saved Wi-Fi profiles, and resets the TCP/IP stack to defaults.

Wi-Fi is unreliable, Ethernet shows “identifying” forever, the VPN client says no internet adapter is present, DNS resolution returns the wrong sites — your network stack is in a tangled state from accumulated driver installs, VPN clients, security software, and ad-hoc fixes. Rather than diagnose each layer, you can reset the whole stack in one command and start with a clean configuration.

What causes this

The Windows network stack has six layers each with their own state: hardware (adapters), drivers (binaries and INF), the TCP/IP stack (Winsock, NetBT, DHCP), the network profiles (Public/Private/Domain for each SSID and Ethernet connection), the routing table, and DNS cache. Each layer can hold stale state. VPN clients (Cisco AnyConnect, OpenVPN, WireGuard) install virtual adapters that may stick around after uninstall. Security software hooks the Winsock layer with Layered Service Providers (LSPs) that survive the software’s removal.

Resetting all of this requires multiple commands or one consolidated Network Reset action.

Method 1: Use the Settings > Network Reset one-click

The cleanest path for Windows 11. Removes every network adapter (including virtual ones), clears all saved profiles, and reboots the PC.

1. Open Settings → Network & internet → Advanced network settings.
2. Scroll down and click Network reset.
3. Click Reset now → Yes.
4. Windows reinstalls all network adapters, clears every Wi-Fi password, removes VPN virtual adapters, and resets TCP/IP settings to defaults.
5. The PC reboots after 5 minutes. Save any open work before clicking Reset now.
6. After the reboot, reconnect to Wi-Fi (you’ll need to enter passwords again) and reconfigure any static IP or DNS settings that were custom.

Plan ahead: have your Wi-Fi password and any VPN credentials available before running this. Reinstall your VPN client after the reset to get its virtual adapter back.

Method 2: Command-line reset (more granular)

Use this if Settings is unavailable or you want to reset specific layers without nuking all profiles.

1. Open Terminal (Admin) from the Start right-click menu.
2. Reset each network layer in turn:

   # Reset Winsock (clears LSPs from removed security software)
   netsh winsock reset
   
   # Reset TCP/IP stack
   netsh int ip reset
   
   # Reset IPv6 settings
   netsh int ipv6 reset
   
   # Release current DHCP lease
   ipconfig /release
   
   # Renew DHCP lease
   ipconfig /renew
   
   # Flush DNS cache
   ipconfig /flushdns
   
   # Register DNS entries
   ipconfig /registerdns
   
   # Reset routing table
   route -f
   
   # Restart the network stack services
   net stop dhcp
   net stop dnscache
   net start dhcp
   net start dnscache

3. Reboot. The combination of winsock reset and int ip reset requires a reboot to complete.

This is the equivalent of Method 1 but preserves Wi-Fi profiles and the list of installed network adapters. Use this when the issue is at the TCP/IP / Winsock layer rather than at the adapter or profile layer.

Method 3: Manually rebuild network profiles

When the issue is specifically network profiles (Public/Private confusion, missing or stale SSIDs).

1. Open Terminal (Admin).
2. List saved Wi-Fi profiles:

   netsh wlan show profiles

3. Delete a specific profile by name:

   netsh wlan delete profile name="Old Office WiFi"

4. Delete all saved Wi-Fi profiles at once:

   netsh wlan delete profile name=* i=*

5. For network profile types (Public/Private), open Settings → Network & internet → Wi-Fi → (your network) → Network profile type and set correctly.
6. For Ethernet, use Set-NetConnectionProfile -InterfaceAlias "Ethernet" -NetworkCategory Private in PowerShell.

This is targeted and preserves the rest of the network stack — best for “one bad SSID” cases.

How to verify the fix worked

• Open Settings → Network & internet. Each adapter (Wi-Fi, Ethernet, Bluetooth) should show Connected with a green checkmark.
• Run Test-NetConnection -ComputerName 8.8.8.8 in PowerShell. PingSucceeded: True; NameResolutionSucceeded: True.
• Open a browser to a known site. Page loads at normal speed.

If none of these work

If network issues persist after a full Network Reset, the problem is likely driver-level or hardware-level. Reinstall the network adapter driver from the laptop or motherboard manufacturer’s support page (not Windows Update, which lags on Wi-Fi drivers). For desktops with a USB or PCIe Wi-Fi card, try a different USB port or a different PCIe slot. For Ethernet that’s slow to negotiate, test with a different cable — old Cat 5 cables fail at gigabit speeds on long runs. For chronic Wi-Fi disconnects after reset, the router’s 2.4 GHz radio may be conflicting with another nearby device — switch to 5 GHz exclusively or rename the SSID to add a separate 5 GHz-only network. Persistent failure after all of this points to either a defective network adapter or motherboard fault — verify by booting a Linux live USB and seeing if networking works there; if it does, the issue is Windows-side and warrants a clean install.

Bottom line: A single Settings > Network Reset clears every accumulated bit of network state and lets you start clean — use it as the first step when multiple network issues stack up.
