获取网络适配器连接状态的powershell命令

Question

我正在试图找到一个Powershell命令，它将为所有网络适配器提供连接状态，对于连接等于“无网络访问”的适配器，禁用并重新启用适配器。

首先，我需要获得正确的状态，我尝试了以下命令，但它只显示物理连接。请注意，即使连接状态显示“无网络访问”，它们的状态也处于上升状态。

Get-NetAdapter -physical

但是，我试图针对的是连接性状态，如网络部分所示

在@postanote应答上扩展，调用Get-NetConnectionProfile一次并存储结果更有效。我还使用了-eq而不是-match来确保可预测的结果。此外，如果它超过1比1的关系，结果可能是不可预测的。他的回答在windows 10上行不通。

#get profiles and adapters
$Profiles = Get-NetConnectionProfile
$Adapters = Get-NetAdapter -Physical

#loop on adapters
$Results = $Adapters | ForEach-Object {
    #get the current adapter
    $Adapter = $PSItem
    #find the associated profiles
    $AdapterProfiles = $Profiles | where {$Adapter.ifIndex -eq $_.InterfaceIndex}

    #output the merged results by looping on the profiles
    $AdapterProfiles | 
         Select-Object @{n='Name';e={$Adapter.Name}},
                       @{n='DeviceName';e={$Adapter.DeviceName}},
                       @{n='InterfaceDescription';e={$Adapter.InterfaceDescription}},
                       @{n='Status';e={$adapter.Status}},
                       IPv4Connectivity,
                       NetworkCategory
}

#view the output in a nice interactive table
$results | Out-GridView

替代产出表：

$results | Format-Table

产出：

Name  DeviceName                                     InterfaceDescription                Status IPv4Connectivity NetworkCategory
----  ----------                                     --------------------                ------ ---------------- ---------------

Answer 2

使用WMI来完成这个任务。

get-wmiobject win32_networkadapter | select netconnectionid, name, InterfaceIndex, netconnectionstatus

查看网络连接状态。你会在那里找到一个价值。这就是连接状态。

断开连接

1

连接中

2

已连接

3.

断开

4.

硬件不存在

5

硬件禁用

6

硬件故障

7

媒体断开

8

鉴证

9

认证成功

10
