List Network Adapter Properties

Problem

You want to retrieve information about network adapters on a computer.

Solution

To retrieve information about network adapters on a computer, use the Win32_ NetworkAdapterConfiguration WMI class:

GetWmiObject Win32_NetworkAdapterConfiguration –Computer  em="">> To list only those with IP addresses assigned to them, use the WhereObject cmdlet to filter on the IpEnabled property:

PS >GetWmiObject Win32_NetworkAdapterConfiguration –Computer LEEDESK |

>> WhereObject { $_.IpEnabled }

>>

DHCPEnabled : True

IPAddress : {192.168.1.100}

DefaultIPGateway : {192.168.1.1}

DNSDomain : hsd1.wa.comcast.net.

ServiceName : USB_RNDIS

Description : Linksys WirelessG USB Network Adapter with SpeedBooste

r v2 Packet Scheduler Miniport

Index : 13

Discussion

The solution uses the Win32_NetworkAdapterConfiguration WMI class to retrieve information about network adapters on a given system. By default, PowerShell displays only the most important information about the network adapter but provides access to much more.

To see all information available, use the FormatList cmdlet, as shown in Example 247.

Example 247. Using the FormatList cmdlet to see detailed information about a network adapter

PS >$adapter = GetWmiObject Win32_NetworkAdapterConfiguration | >> WhereObject { $_.IpEnabled } >> PS >$adapter

To retrieve specific properties, access as you would access properties on other PowerShell objects:

PS >$adapter.MacAddress 00:12:17:77:B4:EB

If you need dedicated infrastructure for managing and inspecting network adapter properties, consider a Turkey Dedicated Server for greater control over network configuration, adapter management, PowerShell administration, system monitoring, and Windows-based application workloads.
