使用批处理，如何确定您是否已连接到WiFi网络

Using Batch, how to determine whether or not you are connected to a WiFi network?

本文关键字：连接 WiFi 网络 是否 批处理 何确定      更新时间：2023-10-16

使用netsh wlan connect name="your network_name"您可以请求连接到WiFi网络，但不能确定您是否已连接。

那么，在批处理中，检查我是否已连接到WiFi网络是什么命令行？（WiFi网络可能会或可能无法访问网络。）[它也适用于移动点孔]

如果连接，则应显示YES，

如果未连接，则应显示NO，

因为我想根据得到的结果来运行一个循环。

有人可以编写良好的工作批处理程序！！和C （如果可能的话）

我尝试的是：

WMIC /node: ”PutYourPCNameHere” path WIN32_NetworkAdapter where (NetConnectionID="Wi-Fi") get NetConnectionStatus

，但是我们不能循环。所以我不知道如何继续！

和

@echo off
ECHO Checking connection, please wait...
PING -n 1 www.google.com|find "Reply from " >NUL
IF NOT ERRORLEVEL 1 goto :SUCCESS
IF     ERRORLEVEL 1 goto :TRYAGAIN
:TRYAGAIN
ECHO FAILURE!
ECHO Let me try a bit more, please wait...
@echo off
PING -n 3 www.google.com|find "Reply from " >NUL

IF     ERRORLEVEL 1 goto :TRYIP
:TRYIP

@echo off

:TRYROUTER

ECHO Lets try pinging the router....
ping -n 2 192.168.1.1|find "Reply from " >NUL
IF NOT ERRORLEVEL 1 goto :ROUTERSUCCESS
IF     ERRORLEVEL 1 goto :NETDOWN
:ROUTERSUCCESS
ECHO It appears that you can reach the router, but internet is unreachable.
goto :FAILURE
:NETDOWN
ECHO FAILURE!
ECHO It appears that you having network issues, the router cannot be reached.
goto :FAILURE
:SUCCESSDNS
ECHO It appears that you are having DNS issues.
goto :FAILURE
:SUCCESS
ECHO You have an active Internet connection
pause
goto END
:SUCCESS2
ECHO You have an active internet connection but some packet loss was detected.
pause
goto :END
:FAILURE
ECHO You do not have an active Internet connection
pause
goto :END
:END

但这无法在移动热点（没有互联网）

上工作
C:Windowssystem32>netsh wlan show interfaces
There is 1 interface on the system:

是两个状态的输出，连接而未连接。

因此，测试Signal是否出现在输出中，表示是否连接。

C:Windowssystem32>netsh wlan show interfaces | Findstr /c:"Signal" && Echo Online || Echo Offline
Offline
C:Windowssystem32>netsh wlan show interfaces | Findstr /c:"Signal" && Echo Online || Echo Offline
    Signal                 : 93%
Online

&&和 ||是速记if命令

请参阅我的CMD备忘单。在此处命令运行.bat文件
