Need Help with Getting IP and Adaptor Name (NetConnectionID) using WMI

PowerShell Help
1

I am trying to create a html report using Creating HTML Reports in PowerShell by Don Jones. What am trying to get to is I would like to get the IP address from Win32_NetworkAdapterConfiguration and NetConnectionID from Win32_NetworkAdapter

Below is the function I am using but the problem is when I output the psobject, NetConnectionID are listed together and not against the IPaddress.

For example

This is how I get

Adaptor Name IP Address Default IPGateway IPSubnet

Local Area Connection Local Area Connection 2 192.168.100.10 192.168.100.1 255.255.255.0

                                                                                        192.168.101.10        192.168.101.1                  255.255.255.0

This is how I want

Adaptor Name IP Address Default IPGateway IPSubnet

Local Area Connection 192.168.100.10 192.168.100.1 255.255.255.0

Local Area Connection 2 192.168.101.10 192.168.101.1 255.255.255.0

Could you let me know what am doing wrong here and please help

You need to match the adapter to the configuration which you can do by filtering in the configurations index which matches the adapters deviced id

function Get-InfoNIC {
    [CmdletBinding()]
    param(
        [Parameter(Mandatory=$True)][string]$ComputerName
    )
    $nics = Get-WmiObject -class Win32_NetworkAdapterConfiguration -ComputerName $ComputerName -Filter "IPEnabled=True"
    foreach ($nic in $nics) {
        
        $index = $nic.Index
        
        $props = @{'IP Address'=$nic.IPAddress[0];
                   'Default IPGateway'=$nic.DefaultIPGateway[0];
                   'IPSubnet'=$nic.IPSubnet[0];
                   'Adaptor Name'=(Get-WmiObject -class Win32_NetworkAdapter -ComputerName $ComputerName -Filter "DeviceId = $index" | 
                                   select -ExpandProperty NetConnectionID)}
        New-Object -TypeName PSObject -Property $props
    }
}

If you don’t have a default gateway set your function throws an error and you don’t get anything for that adapter. This is one way to get round that issue:

function Get-InfoNIC {
    [CmdletBinding()]
    param(
        [Parameter(Mandatory=$True)][string]$ComputerName
    )
    $nics = Get-WmiObject -class Win32_NetworkAdapterConfiguration -ComputerName $ComputerName -Filter "IPEnabled=True"
    foreach ($nic in $nics) {
        
        $index = $nic.Index

        if ($nic.DefaultIPGateway) {
          $gateway = $nic.DefaultIPGateway[0]
        }
        else {
          $gateway = "Not Set"
        }
        
        $props = @{'IP Address'=$nic.IPAddress[0]
                   'Default IPGateway'= $gateway
                   'IPSubnet'=$nic.IPSubnet[0]
                   'Adaptor Name'=(Get-WmiObject -class Win32_NetworkAdapter -ComputerName $ComputerName -Filter "DeviceId = $index" | 
                                   select -ExpandProperty NetConnectionID)}
        New-Object -TypeName PSObject -Property $props
    }
}

I’ve also tidied up the properties hash table by removing the semi colons - you don’t need them when putting key-value pairs on separate lines
