Netadapter交换机PowerShell脚本

当我运行这个脚本时，即使

$ethernet

的值不是

$null

，脚本仍然会返回下面的值，因此它会在不应该返回的时候转到else块

Function AdapterSwitcher {

While ($true) {

$Ethernet = Get-NetAdapter | where-object {$_.Status -contains "Up"} | Where-Object {$_.PhysicalMediaType -eq "802.3" -and {$_.Name -notlike "PANGP" }}
 if ($Ethernet -eq $null)
        {
        Write-Host "Ethernet Not Detected, Enabling WiFi"
            #When the value is null this means that there is no wired connection and the wireless must be enabled
            $WiFiNetadapter = get-netadapter | where-object {$_.Status -contains "Up"} | Where-Object {$_.PhysicalMediaType -eq "Native 802.11"} 
            $WiFiNetadapter | Enable-NetAdapter -Confirm:$false -Verbose


        }
        else
        {
        Write-Host "Disabling WiFi Network Adapter"
            #When the value is not null, the value consists of the object information about the Local Area Network Connection and
            #that the wireless connection needs to be disabled. 
            $WiFiNetadapter = get-netadapter | where-object {$_.Status -contains "Up"} | Where-Object {$_.PhysicalMediaType -eq "Native 802.11"} 
            $WiFiNetadapter | Disable-NetAdapter -Confirm:$false -Verbose }
            Start-Sleep -s 2
    }
        Start-Sleep -s 3
        }

            #Remove-Variable -Name WIRED -Force

有人能告诉我为什么吗？这没有逻辑意义

我不确定While循环在做什么，但是操作符都关闭了。看看这里的区别

write-host "Disabling Network Adapter"

您似乎还试图启用已处于“启动”状态的Wifi适配器。如果它的状态为“启动”…它已启用。试试这个

    $Ethernet = Get-NetAdapter | Where-Object {($_.Status -eq "Up") -and ($_.PhysicalMediaType -eq "802.3") -and ($_.Name -ne "PANGP" )}

    if (!($Ethernet)) {

        #...do something

    }

这项工作：

function AdapterSwitcher {

        $Ethernet = Get-NetAdapter | Where-Object {($_.Status -eq "Up") -and ($_.PhysicalMediaType -eq "802.3") -and ($_.Name -ne "PANGP" )}

            if (!($Ethernet)) {

                $wifi = Get-NetAdapter | Where-Object {$_.PhysicalMediaType -like '*802.11*'}

                Enable-NetAdapter -Name $wifi.Name -Confirm:$false

            else {Disable-NetAdapter -Name $wifi.Name -Confirm:$false

    }

}

如果情况需要更改，则您的

。如果（$null-eq$Ethernet）

，则应为

。如果
$Ethernet
始终具有数据，则
else{}
条件将始终为真。问题是您希望对每个网络适配器执行条件求值吗？您的代码只检查了一次
$Ethernet
集合。请参阅的可能重复：恐怕您错了，我没有启用启动的Wifi适配器-PhysicalMedia类型是802.3，即Ethernet，此脚本强制计算机在停靠或取消停靠时进行切换，以便您不能同时打开以太网和Wifi。请看这一行…$WiFiNetadapter=get netadapter |其中对象{$\状态-包含“Up”}其中对象{$\物理媒体类型-eq“Native 802.11”}$WiFiNetadapter |启用NetAdapter-确认：$false-详细。。。。您肯定会得到一个已经启动的网络适配器，然后启用它。你在下面发布的有效函数从分配$WiFiNetadapter中删除了该条件。啊，是的，抱歉-检查了我发布的修订工作版本-修复了该问题@罗伊斯顿是的，我看见你修好了。我也没有错，我鼓励大家也看看我们运营商在获得$Ethernet方面的差异。Thanks@Royston嘿，小家伙，在我解决你的问题的时候，在你编辑的帖子之前，帮我找到答案，这没什么害处。不管怎样，很高兴它起作用了！
