Network adapters

Richard Siddaway Richard Siddaway Profile: Richard Siddaway

The WMI classes Win32_NetworkAdapter and Win32_NetworkAdapterConfiguration have seen a lot of use over the years. They can be a bit fiddly to use which is why the NetAdapter module in Windows 8/2012 is a so welcome.

Lets start by looking at basic information gathering

PS> Get-NetAdapter | ft -a

Name     InterfaceDescription                        ifIndex Status MacAddress        LinkSpeed
—-     ——————–                        ——- —— ———-        ———
Ethernet NVIDIA nForce 10/100/1000 Mbps Ethernet          13 Up     00-1F-16-63-F5-DF  100 Mbps
WiFi     Qualcomm Atheros AR5007 802.11b/g WiFi Adapter   12 Up     00-24-2B-2F-9C-A5   54 Mbps

We get the Name & description, status, MAC address and link speed as the default display. Contrast with Win32_NetworkAdapter for the same two interfaces

ServiceName      : athr
MACAddress       : 00:24:2B:2F:9C:A5
AdapterType      : Ethernet 802.3
DeviceID         : 10
Name             : Qualcomm Atheros AR5007 802.11b/g WiFi Adapter
NetworkAddresses :
Speed            : 54000000

ServiceName      : NVNET
MACAddress       : 00:1F:16:63:F5:DF
AdapterType      : Ethernet 802.3
DeviceID         : 11
Name             : NVIDIA nForce 10/100/1000 Mbps Ethernet
NetworkAddresses :
Speed            : 100000000

Notice the ifIndex from Get-NetAdapter & DeviceId from Win32_NetworkAdapter.  Two different numbers to identify the device.

What else can Get-NetAdapter tell us:

Notice the CimClass property ROOT/StandardCimv2:MSFT_NetAdapter   – this is one of the new WMI classes introduced in Windows 8.  Does this class have any methods?

These will be investigated in other posts – maybe we get cmdlets to work with these as well
