使用批处理，如何确定您是否连接到wifi网络？ [英] Using batch, how to determine whether or not you are connected to a wifi network?

问题描述

使用 netsh wlan connect name =your network_name您可以请求连接到WiFi网络，但无法确定您是否已连接。



那么，在Batch中，检查我是否连接到WiFi网络的命令行是什么？ （WiFi网络可能有也可能没有网络访问权限。）



如果已连接，则应显示YES，



如果没有连接，它应该显示NO，



因为我想根据我得到的结果运行一个循环。



所以有人可以编写好的工作批处理程序！或c ++（如果可能的话）



我尝试过：



WMIC / node：PutYourPCNameHere路径WIN32_NetworkAdapter其中（NetConnectionID =Wi-Fi）获取NetConnectionStatus



但我们不能放置if循环。所以我不知道怎么办!!



或

Using netsh wlan connect name="your network_name" you can request to connect to a WiFi network, but can't be sure whether or not you are connected.

So, in Batch, what would be a command line to check whether or not I am connected to a WiFi network? (The WiFi network may, or may not, have network access.)

If Connected, It should display YES,

If NOT Connected, It should display NO,

because I want to run a loop depending upon the results I get.

So can someone write good working batch program!! or c++(if possible too)

What I have tried:

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

but we cant put if loops. So I dont know How to proceed !!

or

@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 NOT ERRORLEVEL 1 goto :SUCCESS2
IF     ERRORLEVEL 1 goto :TRYIP

:TRYIP
ECHO FAILURE!
ECHO Checking DNS...
ECHO Lets try by IP address...
@echo off
ping -n 1 216.239.37.99|find "Reply from " >NUL
IF NOT ERRORLEVEL 1 goto :SUCCESSDNS
IF     ERRORLEVEL 1 goto :TRYROUTER

:TRYROUTER
ECHO FAILURE!
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

但这无法解决热点和其他无线网络但没有网络连接。

But this fail to work over hotspots and other wifi but no internet connections.
