blocks|key|826398|text|您可以在PowerShell中使用WMI来完成此任务。假设有一个设备名称中包含Wireless的网络适配器，则这一系列命令可能如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|826399|$adaptor+=+Get-WmiObject+-Class+Win32_NetworkAdapter+%7C+Where-Object+{$_.Name+-like+"*Wireless*"}

You can use WMI from within PowerShell to accomplish this. Assuming there is a network adapter who's device name has Wireless in it, the series of commands might look something like the following:

<pre><code>$adaptor = Get-WmiObject -Class Win32_NetworkAdapter | Where-Object {$_.Name -like "*Wireless*"}
$adaptor.Disable()
$adaptor.Enable()
</code></pre>

Remember, if you're running this with Window's Vista, you may need to run the PowerShell as Administrator.

blocks|key|3983894|text|Zitrax的答案是：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3983895|netsh+interface+set+interface+"InterfaceName"+DISABLED
netsh+interface+set+interface+"InterfaceName"+ENABLED|code-block|syntax|javascript|3983896|是我想要的99%25。但是，他/她遗漏的一条信息是，这些命令必须以管理员身份运行。或者以管理员身份运行cmd.exe并键入它们，或者将它们存储在批处理文件中，然后以管理员身份运行该文件，方法是右键单击该文件并从上下文菜单中选择“以管理员身份运行”。|3983897|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Zitrax's answer:

<pre><code>netsh interface set interface "InterfaceName" DISABLED
netsh interface set interface "InterfaceName" ENABLED
</code></pre>

was 99% of what I was looking for. The one piece of information that s/he left out, though, was that these commands have to be run as an administrator. Either run cmd.exe as an admin and type them in, or store them in a batch file, and then run that file as admin by right clicking on it and choosing "Run as Administrator" from the context menu.

The post of Scott inspired me to write a very small C# / .Net console application, that uses System.Management. You can name the adapter, that you want to restart, as a command line parameter. The code shows some basics about handling devices, that could be useful for others too.

<pre><code>using System;
using System.Management;

namespace ResetNetworkAdapter
{
 class Program
 {
 static void Main(string[] args)
 {
 if (args.Length != 1)
 {
 Console.WriteLine("ResetNetworkAdapter [adapter name]");
 Console.WriteLine("disables and re-enables (restarts) network adapters containing [adapter name] in their name");
 return;
 }

 // commandline parameter is a string to be contained in the searched network adapter name
 string AdapterNameLike = args[0];

 // get network adapter node 
 SelectQuery query = new SelectQuery("Win32_NetworkAdapter");
 ManagementObjectSearcher searcher = new ManagementObjectSearcher(query);
 ManagementObjectCollection adapters = searcher.Get();

 // enumerate all network adapters
 foreach (ManagementObject adapter in adapters)
 {
 // find the matching adapter
 string Name = (string)adapter.Properties["Name"].Value;
 if (Name.ToLower().Contains(AdapterNameLike.ToLower()))
 {
 // disable and re-enable the adapter
 adapter.InvokeMethod("Disable", null);
 adapter.InvokeMethod("Enable", null);
 }
 }
 }
 }
}
</code></pre>

I wrote a simple "Repair.bat" script:

<pre><code>@echo off

Just call it with the name of the NIC, renamed as i.e. "WLAN" so I does not have spaces, type "Repair WLAN" into cmd does the trick.
I'll place it into system32 and make a task of it or see how to integrate it into the network context menu...

OS: Vista enterprise

When i switch between my home and office network, i always face issues with getting connected to the network. Almost always I have to use the diagnostic service in 'Network and sharing center' and the problem gets solved when i use the reset network adapter option.

This takes a lot of time (3-4 min) and so i was trying to find either a command or a powershell script/cmdlet which i can use directly to reset the network adapter and save myself these 5 mins every time i have to switch between the networks. Any pointers?

Command/Powershell script to reset a network adapter

操作系统: Vista企业版当我在家庭和办公室网络之间切换时，我总是面临连接到网络的问题。我几乎总是要使用“网络和共享中心”中的诊断服务，当我使用重置网络适配器选项时，这个问题就解决了。这需要很多时间(3-4分钟)，所以我试图找到一个命令或powershell脚本/cmdlet，我可以直接使用它们来重置网络适配器，并在每次必须在网络之间切换时节省这5分钟。有什么建议吗？
