Resetting network settings in Windows is usually the last resort worth trying to resolve complex problems with accessing a local network or the Internet. This resets the network adapter settings on the computer, the TCP / IP stack settings to the standard settings in clean Windows, removes and reinstalls all network adapters on the computer. In this article, we will look at the features of resetting network settings in Windows from the graphical interface and using the command line.
Before resorting to resetting network settings, make sure that you have tried all the standard network diagnostic tools: checked the IP settings, the operation of the router / router / provider, updated network adapter drivers, restarted the computer, used the built-in Windows Network Troubleshooter (command msdt.exe /id NetworkDiagnosticsNetworkAdapter ), etc. .d. If none of the tools helped to fix the network problem, you can try resetting the network settings.
Save your current Windows network settings.
When resetting the network in Windows, all the settings that you set manually will be lost: IP addresses, DNS servers, static routes, network driver settings, saved Wi-Fi networks, etc. will be cleared. Therefore, it is important to save the current settings before resetting.
List network adapters:
Get-NetAdapter|select name,InterfaceIndex,InterfaceDescription,InterfaceOperationalStatus,MediaConnectionState,DriverInformation|ft
For all connected network adapters, check if they receive settings automatically (via DHCP) or manually:
Get-NetIPInterface -InterfaceIndex 7
If the value for the interface is Dhcp=Disabled , then the IP settings for the adapter are set manually and you need to save the current settings to a file:
Get-NetIPConfiguration -InterfaceIndex 7 >>c:\network_settings.txt
Multiple IPs (aliases) can be assigned to one interface in Windows.
Display and record all static routes in the routing table (from the Persistent Routes section):
Route print
Use PowerShell to list VPN connections, write down their settings:
Get-VpnConnection
In my case, the settings for saved VPN connections were not reset. Also, the OpenVPN Wintun virtual adapter (adapter for connecting to an OpenVPN server) was not removed.Output WLAN profiles and save wireless network settings to a file:
netsh wlan show profileSave your Winsock settings:
netsh wlan export profile name="Xiaomi_20F5" key=clear folder=c:\ps
netsh winsock show catalog > c:\winsock-backup.txt
After resetting the network, the saved information will help you restore all manually configured network settings.
Reset network settings from the Windows Control Panel.
On Windows 10 (1607+), Windows 11 and Windows Server 2019/2022, you can reset network settings from the Settings panel. Go to Settings -> Network (or run the ms-settings shortcut: ms-settings:network). Click the Network reset -> Reset now button.
Confirm network settings reset. Windows will clear all network settings and remove network cards (network adapters will not show up in the Control Panel). The network settings will be reset to factory defaults. Windows will automatically restart after 5 minutes.
After booting, Windows will detect all connected network adapters and install the drivers. It remains to configure the network connection settings and check if the problem is fixed.
Reset network settings from the Windows command line.
All the same actions that the network reset procedure performed from the Settings panel can be performed from the command line.
ipconfig /flushdnsReset your WinSock settings:
netsh winsock reset
Successfully reset the Winsock Catalog. You must restart the computer in order to complete the reset.
The command resets the settings in the registry branch HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WinSock2\Parameters . At the same time, the old settings are saved to the Protocol_Catalog_Before_Reset branch.

Reset all Windows Defender Firewall rules:
netsh advfirewall reset
PowerShell also has a separate command to reset advanced settings for a specific network adapter. First you can get the current adapter settings:
Get-NetAdapterAdvancedProperty -Name Ethernet0|ft -AutoSize

Here you can display Jumbo Packet settings, VLAN settings, buffer settings, etc.
To reset these settings, run:
Reset-NetAdapterAdvancedProperty -Name Ethernet0
Restart your computer and set all network settings again. If the computer is configured to automatically obtain an IP address and network settings from a DHCP server, nothing else needs to be configured.
