無法使用cmd連接到無線網絡

我嘗試透過 FTP 將手機連接到 PC，並使用 cmd 透過 Windows 資源管理器開啟 FTP。

下面是程式碼：

@echo off 
echo Setup connection to ftp 192.168.43.1 
ipconfig | findstr /I "192.168.43.1"
:: Opens ipconfig and searches for string "192.168.43.1" in the output of ipconfig to check if 192.168.43.1 is connected 
if %errorlevel% == 0 ( 
echo Connection set
%windir%\explorer.exe ftp://192.168.43.1:8888/ 
) else ( 
echo Connection not set 
echo Setting up connection... 
netsh wlan connect name="sdc-yayjg"
:: "sdc-yayjg" is the host name of 192.168.43.1
timeout 3 > NUL 
echo Opening ftp 192.168.43.1
ipconfig | findstr /I "192.168.43.1" 
if %errorlevel% == 0 ( 
echo Connection set
%windir%\explorer.exe ftp://192.168.43.1:8888/ 
) else ( 
echo FAIL: Connection not set. 
echo Press any key to exit. 
pause > NUL

我將這些程式碼儲存在批次檔中，當我執行批次檔時，cmd 會開啟一毫秒左右，然後退出，我的意思是 cmd 視窗只會閃爍幾毫秒，然後什麼事也不會發生。沒有設定任何連接或任何連接。
這些代碼在沒有“findstr”命令的情況下也可以正常工作。我無法刪除該命令，因為它對於檢查網路狀態非常重要。

嘗試以下程式碼（經過編輯以提高未來用戶的模組化程度，並稍微改進程式碼以獲得更好的用戶體驗）：

@echo off
goto setup
:setup
title FTP Connection w/ network support 

SET "FTP=192.168.43.1"
:: Location of the FTP server

SET "FTPPORT=8888"
:: The FTP server's port

SET "WIRELESS=sdc-yayjg"
:: The network where the FTP server resides

SET "TRIES=0"
:: Please do not tamper with.

SET "MAXTRIES=3"
:: How many tries before failure

SET "TIMETOCONNECT=3"
:: How much time to give to connect to the network

echo Setting up connection to FTP %FTP%...
goto check1
:check1
if %TRIES% LSS %MAXTRIES% (
SET /A "TRIES=TRIES+1"
goto check2
) else (
goto Fail
)
:check2
echo Checking for FTP Server presence...
ipconfig | findstr /I "%FTP%"
:: Opens ipconfig and searches for %FTP%. (in this case it's "192.168.43.1") in the output of ipconfig to check if 192.168.43.1 is connected 
if %errorlevel% EQU 0 ( 
goto 0
) else ( 
echo Presence not found. Assuming connection not set...
goto 1
)
:1
echo Connection not set after %TRIES% times.
echo Setting up connection... 
netsh wlan connect name="%WIRELESS%"
:: This script assumes that WIRELESS (sdc-yayjg) houses the IP (192.168.43.1)
timeout %TIMETOCONNECT% > NUL 
goto check1
:Fail
echo FAIL: Connection not set after %MAXTRIES% tries. 
echo Press any key to exit. 
pause > NUL
exit
)
:0
echo Internet Connection set - Connecting to FTP via Windows Explorer...
%windir%\explorer.exe ftp://%FTP%:%FTPPORT%/ 
echo Connection Sucessful. Windows Explorer should now open...
echo Press any key to close this window.
pause > NUL
exit

如果上面的程式碼不起作用，則原始程式碼（根據 OP 進行一些修飾性變更）如下。

@echo off 
echo Setting up connection to FTP 192.168.43.1...
goto Check
:check
ipconfig | findstr /I "192.168.43.1"
:: Opens ipconfig and searches for 192.168.43.1 in the output of ipconfig to check if 192.168.43.1 is connected 
if %errorlevel% == 0 ( 
goto 0
) else ( 
goto 1

)
:: Close your if statements!
:1
echo Connection not set 
echo Setting up connection... 
netsh wlan connect name="sdc-yayjg"
:: "sdc-yayjg" is the host name of 192.168.43.1
timeout 3 > NUL 
echo Opening ftp 192.168.43.1
ipconfig | findstr /I "192.168.43.1" 
if %errorlevel% == 0 ( 
goto 0
) else ( 
echo FAIL: Connection not set after three tries. 
echo Press any key to exit. 
pause > NUL
:: Close your if statements!
exit
)
:0
echo Internet Connection set - Connecting to FTP via Windows Explorer...
%windir%\explorer.exe ftp://192.168.43.1:8888/ 
exit
