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 <ComputerName> 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:
