Checking Network Adapter Speed

by Feb 4, 2013

Sometimes, just one line of PowerShell code gets you all the information you may have needed. There is a .NET type called NetworkInterface, for example, that lists all of your network adapters, their speed and status:

PS> [System.Net.NetworkInformation.NetworkInterface]::GetAllNetworkInterfaces() | Select-Object -Property Description, Speed, OperationalStatus 

Description                                Speed OperationalStatus
-----------                                ----- -----------------
Broadcom 802.11n Network Adapter        52000000                Up
VirtualBox Host-Only Ethernet Adapter  100000000                Up
