Powershell to Access Database, can't get IPaddress

I am making an inventory PS script with access and everything is going well until I get to the network portion of my code.  For some reason that I must be overlooking or just do not know I cant get the fields to populate in the database.  Some will like the network card and device_name. But fields like IPaddress, subnetmask, default gateway, etc... will not return any value, when I check the database its blank.  I am confused and need some direction, any help is appreciated!  Thank you!

Here is a snippet of my network function:

# ==============================================================================================
# Function Name 'Update-Network' - Gathers Network info using WMI
# ==============================================================================================
Function Update-Network {"Updating Network Info"
	foreach ($strComputer in $colComputers){
			$NetItems = gwmi Win32_NetworkAdapterConfiguration -Comp $StrComputer | `
			where{$_.IPEnabled -eq "True"}
		}
	foreach ($objItem in $NetItems){
			$RecordSet.AddNew()	
			$RecordSet.Fields.Item("Device_Name") = $StrComputer
			$RecordSet.Fields.Item("Network_Card") = $objItem.Caption+" (enabled)"
			$RecordSet.Fields.Item("DHCP_Enabled") = $objItem.DHCPEnabled
			$RecordSet.Fields.Item("IP_Address") = $objItem.IPAddress
			$RecordSet.Fields.Item("Subnet_Mask") = $objItem.IPSubnet
			$RecordSet.Fields.Item("Default_Gateway") = $objItem.DefaultIPGateway
			$RecordSet.Fields.Item("DNS_Servers") = $objItem.DNSServerSearchOrder
			$RecordSet.Fields.Item("DNS_Reg") = $objItem.FullDNSRegistrationEnabled
			$RecordSet.Fields.Item("Primary_WINS") = $objItem.WINSPrimaryServer
			$RecordSet.Fields.Item("Secondary_WINS") = $objItem.WINSSecondaryServer
			$RecordSet.Fields.Item("WINS_Lookup") = $objItem.WINSEnableLMHostsLookup
			$RecordSet.Update()
		}
} #End Update-Network
