PowerShell Get-NetAdapter

List Your Network Adapters with PowerShell 3.0Get-NetAdapter

PowerShell 3.0 introduces a new family of NetAdapter of cmdlets.  Get-NetAdapter is the default, and its job is to enumerate your computer's network cards (NICs).

The Magic of PowerShell's NetAdapter

To appreciate the elegance of Get-NetAdapter, you have to experienced the uglyness of enumerating network cards using NetSh or VBScript; even with PowerShell 2.0's Get-WmiObject Win32_NetworkAdapterConfiguration it wasn't easy to list NICs.

One aspect of elegance that I admire, especially in scripting, is simplicity.  Therefore to get started all you need is the command: Get-NetAdapter.

Simple Example of Get-NetAdapter

# PowerShell 3.0 lists all your computer's network cards.
Get-NetAdapter

Note 1:  You can find more properties by piping the output into | Get-Member.

Research NetAdapter Properties

Important: Adjust the value of my $Nic variable depending on the results of the simple: Get-NetAdapter command.

Clear-Host
$Nic = "Wi-Fi"
Get-NetAdapter -name $Nic | Format-List Name,`
InterfaceDescription, DeviceName, DeviceWakeupEnable,`
LinkSpeed, NetworkAddress, PromiscuousMode, Status

Note 2:  Take care with the ` backtick; in particular avoid spaces after this command that tells PowerShell to word-wrap to the next line.

Note 3:  Here is an even better plan, research your own properties with:
Get-NetAdapter | Get-Member

Guy Recommends:  A Free Trial of the Network Performance Monitor (NPM)Review of Orion NPM v11

SolarWinds' Network Performance Monitor will help you discover what's happening on your network.  This utility will also guide you through troubleshooting; the dashboard will indicate whether the root cause is a broken link, faulty equipment or resource overload.

What I like best is the way NPM suggests solutions to network problems.  Its also has the ability to monitor the health of individual VMware virtual machines.  If you are interested in troubleshooting, and creating network maps, then I recommend that you try NPM now.

Understanding Get-NetAdapter's Parameters

Employing the -name parameter is a precise method for specifying the network card, and it saves me having to use Powershell's Where-Object statement to filter the network cards.

Let us call for Get-Help and see which other parameters are available for the Get-NetAdapter cmdlet.

#PowerShell NetAdapter parameter research
Clear-Host
Get-Help Get-NetAdapter

Results: I found two interesting parameters -IncludeHidden and -physical.

Research Microsoft's NetAdapter Cmdlet Family

Once you have discovered a useful PowerShell cmdlet such as Get-NetAdapter it's worth investigating alternative verbs; this is how I discovered Enable, Disable and Restart-NetAdapter.

Get-Command -Noun netadapter

CommandType  Name            ModuleName
-----------         ------            ------------
Function Disable-NetAdapter  NetAdapter
Function Enable-NetAdapter   NetAdapter
Function Get-NetAdapter        NetAdapter
Function Rename-NetAdapter NetAdapter
Function Restart-NetAdapter   NetAdapter
Function Set-NetAdapter        NetAdapter

How to Enable or Disabled Your NIC

Here is an example to disable the Wi-Fi's network adapter.

# PowerShell script to disable your network card.
$Nic = 'Wi-Fi'
Disable-NetAdapter -Name $Nic

Note 4:  To reverse the action substitute Enable-NetAdapter for Disable-Network adapter.

Note 5:  See more on PowerShell's Disable-NetAdapter.

NetAdapter Challenge

PowerShell's default verb is 'Get'.  Thus, my challenge is to substitute plain NetAdapter for Get-NetAdapter in the above examples.  Actually, I regard this shortcut as sloppy scripting, but it does explain why other PowerShell commands work the way they do, for example:
Help Disable-NetAdapter
... is really 'Get-Help' Disable-NetAdapter, but as 'Get' is the default verb, the shorter form works.

Guy Recommends: WMI Monitor for PowershellSolarwinds WMI Monitor

Windows Management Instrumentation (WMI) is most useful for PowerShell scripting.

SolarWinds have produced this Free WMI Monitor to take the guess work out of which WMI counters to use for applications like Microsoft Active Directory, SQL or Exchange Server.
