PowerShell script to get network card speed of a Windows Computer
提问by Martin Hollingsworth
What is the PowerShell script to get the speed a specific Windows machine's network card is running at?
获得特定 Windows 机器网卡运行速度的 PowerShell 脚本是什么？
I know this can be done with a WMI query based statement and will post an answer once I work it out.
我知道这可以通过基于 WMI 查询的语句来完成，一旦我解决了，就会发布答案。

A basic command is
一个基本的命令是
Get-WmiObject -ComputerName 'servername' -Class Win32_NetworkAdapter | `
Where-Object { $_.Speed -ne $null -and $_.MACAddress -ne $null } | `
Format-Table -Property SystemName,Name,NetConnectionID,Speed
Note that the ComputerName parameter takes an array so you can run this against multiple computers provided you have rights. Replace the Format-Table property list with ***** to get a more comprehensive list of available properties. You might want to filter on these properties to get rid of entries you aren't interested in.
请注意，ComputerName 参数采用一个数组，因此您可以在拥有权限的情况下对多台计算机运行它。将 Format-Table 属性列表替换为 ***** 以获得更全面的可用属性列表。您可能希望过滤这些属性以去除您不感兴趣的条目。
Using the built in byte Multiplier suffixes (MB, GB etc) would also make the speed more readable depending on your needs. You could specify this as a HashTable entry on the Format-Table -Property array e.g.
根据您的需要，使用内置的字节乘数后缀（MB、GB 等）也会使速度更具可读性。您可以将其指定为 Format-Table -Property 数组上的 HashTable 条目，例如
Format-Table -Property NetConnectionID,@{Label='Speed(GB)'; Expression = {$_.Speed/1GB}}

Starting with Windows 8/Server 2012, you can try Get-NetAdapterand several more specialized commands like Get-NetAdapterAdvancedProperty:
从 Windows 8/Server 2012 开始，您可以尝试Get-NetAdapter一些更专业的命令，例如Get-NetAdapterAdvancedProperty：

You can also use the more comprehensive WMI class MSFT_NetAdapterto create customized output. MSFT_NetAdapteris described here:
您还可以使用更全面的 WMI 类MSFT_NetAdapter来创建自定义输出。MSFT_NetAdapter在这里描述：

Here's a command to list the speed and other properties of enabled (State 2), connected (OperationalStatusDownMediaDisconnected $false), 802.3 wired (NdisPhysicalMedium 14), non-virtual adapters on the local computer:
这是一个命令，用于列出本地计算机上已启用（状态 2）、已连接（OperationalStatusDownMediaDisconnected $false）、802.3 有线（NdisPhysicalMedium 14）、非虚拟适配器的速度和其他属性：
Get-WmiObject -Namespace Root\StandardCimv2 -Class MSFT_NetAdapter | `
Where-Object { $_.State -eq 2 -and $_.OperationalStatusDownMediaDisconnected -eq $false -and `
$_.NdisPhysicalMedium -eq 14 -and $_.Virtual -eq $false } | `
Format-Table Name,Virtual,State,NdisPhysicalMedium, `
@{Label='Connected'; Expression={-not $_.OperationalStatusDownMediaDisconnected}}, `
@{Label='Speed(MB)'; Expression = {$_.Speed/1000000}}, `

My current version, taking out bluetooth and wireless cards (run with powershell -file script.ps1):
我当前的版本，取出蓝牙和无线网卡（使用 powershell -file script.ps1 运行）：
# return network speed as exit code
$speed = Get-WmiObject -Class Win32_NetworkAdapter |
where { $_.speed -and $_.macaddress -and
$_.name -notmatch 'wireless|wi-fi|bluetooth|802\.11' } | select -expand speed
exit $speed/1000000
