Get Active Network Adapter

Recently I had the need to create a script to find out what was the active network adapter in our server, so after some ideas from the web, I came up with a one line PowerShell script that helped me achieve my goal.

Note: Get-NetAdapter is a PowerShell commandlet that’s present on Windows 8 and Windows Server 2012 R2. This command will not work on Windows 7.

Get-NetAdapter | Where-Object {($_.LinkSpeed -eq “1 Gbps”) -and ($_.Status -eq ‘Up’)}

In this line, I’m basically getting the adapter with status ‘Up’ and with a linkspeed equals to ‘1 Gbps’. One can change LinkSpeed property to match your server’s network adapter speed(s).
