With PowerShell 3.0 it’s straightforward to enable a NIC (Network Interface Card), just use a built-in CIM cmdlet called Enable-NetAdapter.

Many scenarios for controlling a network adapter focus on Wi-Fi. However, there maybe other situations where a computers has multiple NICs and you want to choose which one is active.
When grappling with NIC settings, Windows PowerShell v 3.0 offers an easier alternativeto ‘Netsh’ commands such as:
Netsh interface set interface <NIC Name> Enabled
The only problem with PowerShell’s Enable-NetAdapter is that you need to know the Name of your NIC. This is where the cmdlet Get-NetAdapter is a useful precursor.
Research the Names of Your NICs
# PowerShell script to list your network cards.
Get-NetAdapter | FT Name, InterfaceDescription -Auto
Note 1: You can find more properties by appending | Get-Member.
Preliminary step: before you launch PowerShell, right-click and ‘Run as Administrator’.
# PowerShell script to enable one of your NICs.
Enable-NetAdapter -Name ‘Wi-Fi’
Note 2: You may need to change the name ‘Wi-Fi’ for the name of your network card, as revealed by research with Get-NetAdapter.
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.
For testing purposes you may wish to ‘Disable’ the network card, and thus reverse the effect of Enable-NetAdapter.
# PowerShell script to disable your network card.
$YourNic = ‘Wi-Fi’
Disable-NetAdapter -Name $YourNic
Note 3: Remember this: before you launch PowerShell 3.0 ISE, right-click and Run as Administrator.
