clear TCP/IP Gateway using WMI

solution 1:

To clear the gateway, set your gateway to the same IP you use on EnableStatic.

solution 2:

First we use WMI to grab the NIC by name ($NicName):

$Adapter = Get-WmiObject -Class Win32_NetworkAdapter-Filter "NetConnectionID='$NicName'"




Then we get the configuration for the NIC by calling it using the index number of the NIC we got from above:

$Nic = Get-WmiObject -ClassWin32_NetworkAdapterConfiguration -Filter"Index=$($Adapter.Index)"




Next, we need to grab the NIC’s IP and subnet mask so we can assign them again later:

$NicIP =$Nic.IpAddress[0]

$NicMask = $Nic.IpSubnet[0]




The, we set the NIC to DHCP,

$Nic.EnableDhcp() |Out-Null




And then back to static, using the IP and mask we retrieved from above:

$Nic.EnableStatic($NicIp,$NicMask) | Out-Null
